Rainbow Six Siege
R6 siege pc box.jpg
Official Boxart
Release Date: December 1, 2015
Developer: Ubisoft
Publisher: Ubisoft
Series: Rainbow Six
Platforms: Xbox One
PlayStation 4
PC
Genre: First-Person Shooter


Tom Clancy's Rainbow Six Siege is a tactical first person shooter available on the PlayStation 4 and 5, Xbox One and Series S/X, and PC. Players assume the roles of counter-terrorism operators from around the world, and engage in PvP and PvE combat. In regular gameplay, players play as either Attackers or Defenders on maps designed with clearly defined indoor and outdoor regions. Attackers must enter the central structure of the map and complete objectives like defusing bombs, securing a point, or rescuing a hostage, while the Defenders must prevent the Attackers from achieving their objectives and run down the round timer to win. Eliminating the enemy team is also a victory condition. A PvE mode called Terrorist Hunt was available until it was removed in Year 8 Season 3 in 2023.

Players play as "Operators", a roster of characters divided between Attackers and Defenders, with each Operator coming from a counter-terrorist unit background. Each Operator carries a unique Operator gadget that defines their abilities and team role (no Operator may be selected twice by the same team, except in certain modes). In terms of weaponry, each Operator generally has two primary weapon options (three at most, occasionally one) and one or two secondary options. Generally speaking, Rifles and LMGs are used by Attackers, SMGs are used by Defenders, and Shotguns are mostly used by Defenders though sometimes shared with Attackers. Operators of a CTU generally share their sidearm options and their shotgun option. Each Operator also carries a piece of team-specific universal equipment alongside their unique gadget, choosing one from two options.

Also playable are Recruits, who are generic Operators with no special gadgets, instead taking a second piece of universal equipment in place of it. Originally able to use a wide variety of weapons, Recruits were reworked in June 2024's Operation New Blood, which saw the previously generic Recruits become fully-fledged Operators, known as Striker for Attackers and Sentry for Defenders. While originally any number of players could pick and play as Recruit in a match, Striker and Sentry are locked to one per team as with every other operator.

The game also features destructible environments for players to take advantage of, primarily blowing holes in walls for a new entry point to flank opponents, creating windows to defend an area without exposing the player's whole body, or shooting through thin walls to suppress enemies.

All primary and some secondary weapons in the game have "charm mounts" to which keychain-like charms can be attached, which by default appear as sling loops.

Notably, third person weapon animations are completely identical to their first person counterparts. Ejected fired rounds and dropped magazines are physical objects that bounce against surfaces, and can be seen in both first and third person.

As of Year 8 Season 1 Operation Commanding Force, the reloading mechanic is overhauled to be more immersive and "staged" to the likes of Ground Branch. Various actions while the weapon's magazine is out will retain the one bullet in the chamber (if available) and not the magazines that are removed during the animation. Reloading again inserts the magazine and - if the bullet in the chamber is fired - charge the weapon. Prior to this, weapons can reload cancel.

For ease of searching, all weapons on this page are primarily ordered by chronology of addition to the game, with the base game weapons near the top of each weapon category and DLC weapons further down.


The following weapons appear in the video game Rainbow Six Siege:


Pistols

FN Five-seveN

The FN Five-seveN Mark 2 is issued to the FBI SWAT faction, Jaeger Corps operator Nøkk added in Year 4 Season 2 Operation Phantom Sight, rouge Swedish neuroscientist Fenrir, and Attacker Recruit Striker. It appears as the "5.7 USG" (referencing the earlier USG variant). The Five-seveN has an appropriate 20+1 capacity, but its overall effectiveness is offset by low stopping power. A special version was added in Year 5 Season 3 Operation Shadow Legacy, available to operative Zero (as giving Sam Fisher anything other than a 5.7 would be heresy), with a permanent Osprey suppressor affixed to the weapon.

FN Five-seveN Mark 2 - 5.7×28mm FN. This variant is now the standard version of the FN Five-seveN offered by FNH. The Mk2 model has cocking serrations on the front of the slide as well as on the rear. This is a fixed-sight version.

FN FNP-9

The FN FNP-9 is a high capacity, 9x19mm handgun used by the GIGN Operators, the reworked Recruit defender and NIGHTHAVEN Attacker Ace. It is referred to as the "P9". Lion always carries one in a vest holster, in addition to his main sidearm (either another FNP-9 or a Model 586) in his leg holster; the extra pistol is not usable by the player.

GSh-18 Sport

The GSh-18 is a sidearm available to the all five operators (including Finka) originating from Spetsnaz CTU (the depicted CTU is more specifically Alpha Group of FSB, going under the more generic and well-known Spetsnaz name), as well as FBI asset Flores. As with the two pistols mentioned above, it is the Russians' high capacity, low damage 9x19mm caliber pistol. The particular model used in-game is a GSh-18 Sport, a civilian offering intended for competition shooting, evident by the front cocking serrations and lack of trigger safety.

Heckler & Koch USP Tactical

The "P12" is the German equipment designation for the Heckler & Koch USP Tactical, used by the German GSG-9 operatives, reworked Recruits, and NIGHTHAVEN operator Wamai. The loadout icon was originally the same as the FNP-9, but in Update 3.2 the USP was given a new proper icon.

M45/MEU(SOC)

The M45/MEU(SOC) is the other sidearm available to the FBI SWAT operatives with the exception of Castle, who had it swapped for an M870 MCS Masterkey in a later update. It appears as the "M45 MEUSOC" and feeds from standard seven-round magazines. Compared to their Five-seveN, the MEU(SOC) offers substantially higher stopping power at the expense of having close to only a third of the former's magazine capacity at only 7 rounds.

Makarov PM

Though referred to as the improved PMM, the in-game pistol is actually the older Makarov PM, and is issued to the Russian Spetsnaz and NIGHTHAVEN operator Osa. Likely to balance out its small magazine (with most of the game's pistols featuring double-stack magazines holding 15 rounds or more), the weapon is obscenely powerful - it's currently the most powerful sidearm in the game short of magnum handguns like the S&W 586 and the SEALs' Desert Eagle, and doing as much damage per shot as DMRs like the 7.62x51mm SR-25.

SIG-Sauer P226 MK 25

The SAS operators, NIGHTHAVEN operator Kali and DAE operator Tubarão use the SIG-Sauer P226 MK 25 as their default handgun of choice. The choice of this particular model for the SAS is odd, as the military of the UK uses regular P226/P226R pistols under the "L105A1/A2" designation. It also predates the inclusion of a proper US Navy SEAL faction, who, in true tacticool fashion, were given the Desert Eagle as their sidearm instead. Although it should be noted that in-universe, Rainbow is a multinational counter-terrorist group with no set loadouts for their operators, so they would be theoretically free to use whatever armaments they see fit.

SIG-Sauer P226 Navy, this is the version used by the Navy SEALs, easily identifiable by the white anchor on the slide - 9x19mm

Inglis Hi-Power

The Inglis Hi-Power, a Canadian-manufactured version of the Browning Hi-Power, is used by the Canadian JTF2 Operators Buck and Frost, REU operator Iana and 35th Commando Battalion Operator Ram. It appears under the strange name "MK1 9mm". The version used by Iana features custom grips.

Slide released; ready to go. Like the Makarov PM above, the Hi-Power has oddly thick slide serrations; unlike the Makarov, however, these are only on one side.

Desert Eagle Mark XIX

The classically absurd Desert Eagle Mark XIX is used by the Navy SEAL Operators added to the game with the Operation Dust Line expansion, and is also used by the Jaeger Corps operator Nøkk and literal ronin Azami. Contrary to popular belief, the Desert Eagle has been issued to military forces. The Polish GROM (which appears in the game) as well as the Portuguese Special Operations Group both use the Desert Eagle. It appears as the "D-50", similar to its name in other Ubisoft releases around the same time like Far Cry 3. Originally released with a chrome default finish, the Operation Velvet Shell update changed the default finish to black.

A special golden variant (as the "Extravagance" skin) is the sole weapon used in the Golden Gun arcade game mode, which was previously available in limited time events. Obviously inspired by the Goldeneye 007's Golden Gun, it only contains one shot that instantly kills enemies. It also uses an alternate reload animation.

Unlike the SEALs, Nøkk has a more subdued and simple pull-magazine-out-put-magazine-in empty reload animation, and finishes off the animation with a rack of the slide instead of using the slide release.

Beretta 92

The Beretta 92 is used by the BOPE Operators from the Operation Skull Rain expansion and Aruni from the Operation Neon Dawn expansion, labeled in-game as "PRB92." Presumably, these pistols were intended to be vintage Taurus PT92 handguns, but the rounded trigger guard and magazine release located on the butt of the grip are features of the first model Beretta 92. It also has the wider cocking serrations on the slide from the newer PT92 models.

On another note, the defender Caveira wields a unique "Luison" version that comes pre-equipped with a mineral-based suppressor and fires non-lethal, subsonic rounds. Due to balancing, Lusion used to be able to deal more damage than a .50 caliber handcannon at close range before being nerfed down, where it now only deals slightly more damage than the Spetsnaz' Makarov (which is still a compact handcannon that puts all other non-magnum sidearms to shame). The magazine size of the Luison is also nerfed compared to the standard PRB92, at 12 instead of 15 rounds.

Beretta 92, the first Beretta 92 Series model produced, noted by rounded trigger guard, butt located magazine release, and frame mounted safety (pre-decocking safety) - 9x19mm

Caveira wields her 92 one-handed while in "Silent-Step" mode. Note that the "custom suppressor" is just the same Osprey 9 as other pistols, wrapped in a mysterious shroud.
Capitão ejects a magazine, note the low button release. This leads to a rather flamboyant "holding the pistol as high as possible while dropping the mag" show of reloading.
Caveira racks the slide to chamber a round on her Luison. The alleged "non-lethal" rounds seem just as lethal as other pistols, though; its only difference is that it will only incapacitate targets (unless the victim is the last person alive on the enemy team) to allow Caveira a chance to interrogate them and expose the rest of the enemy's positions.
One of the Skull Rain loading screens shows the actual PT92, however, a current production PT92AF to be precise.

SIG-Sauer P229 Elite

The SIG-Sauer P229 Elite is used by the SAT Operators from the Operation Red Crow expansion, the FES operator Goyo from the Operation Ember Rise expansion and the NIGHTHAVEN Attacker Grim from the Operation Brutal Swarm expansion. It appears as simply the "P229". What appears to be a SIG-Sauer P229 is seen on the "Custom Game" icon.

SIG-Sauer P229 Elite - .40 S&W
P229 in the weapon inspection screen. Note the Elite beavertail frame with front strap checkering; sadly, "thick slide serration syndrome" has claimed another victim - though, like the Hi-Power that came before it, only one set (the rear set, in this case) have been altered.

Heckler & Koch USP Compact

The Heckler & Koch USP Compact is used by Spanish GEO Operators Jackal and Mira, GIGR guest Operator Oryx and COT Operator Brava. It appears as the "USP40".

Followed by a tug of the slide, similar to the full-size USP used by the GSG-9 operators.

QSZ-92

The 9x19mm variant of the QSZ-92 is used by the SDU Operators featured in the Operation Blood Orchid DLC and STAR-NET Aviation's Thunderbird from the Operation North Star expansion, but with a lowered capacity of 10 rounds instead of 15. It appears as the "Q-929".

QSZ-92 - 9x19mm

PR-15 Ragun

The Polish PR-15 Ragun was added to the game with the Operation Blood Orchid expansion. It is referred to as the "RG15", and is used by the GROM Defender Ela and GROM Attacker Zofia (who was released in Operation White Noise, the following season), and Inkaba Task Force (a fictional anti-poaching unit seemingly inspired by the real-world Black Mambas APU) Defender Melusi. It features a permanently-attached SIG ROMEO1 reflex sight which was originally exclusive to this pistol in-game before the inclusion of the Taurus 4510PLYFS with the Italian GIS faction. Interestingly, pre-release renders of Ela showed her instead holding a SIG-Sauer P228 with a red-dot sight.

PR-15 Ragun - 9x19mm

Meleeing with the PR-15; oddly, despite showing proper trigger discipline during reloads, Ela keeps her finger firmly wrapped around the trigger while pistol-whipping.

CZ 75 Automatic

The CZ 75 Automatic using 26 round magazines was added to the game with the Operation White Noise expansion. It is referred to as the "C75 Auto", and is used by the 707th Special Mission Battalion operators Dokkaebi and Vigil, NIGHTHAVEN attacking operator Kali, Defender Recruit Sentry, and Garda EDU defender Thorn. It is classified as a Machine Pistol in-game.

The weapon cannot accept any attachments beyond a suppressor, despite having a rail on top of the sights, although it technically does come in with a compensator and vertical grip in the form of the spare magazine mounted on the lower frame (which is not usable for quick reloads and its also empty).

Aiming down the sights; the pistol is held quite a bit closer than most other pistols, likely to reduce the field of view as a balancing measure. Despite the Picatinny rail that is part of the rear sight, it cannot accept other sight options, like the M9A1 in Call of Duty: Ghosts.

SIG-Sauer 1911 TACOPS

The SIG-Sauer 1911 TACOPS is the sidearm of Delta Force and GSUTR ("Grim Sky Urban Tactical Response Team", the CTU added in Year 3 Season 3, Operation Grim Sky) Attacker Operator Maverick and Garda ERU Defender Thorn. It is equipped with Hogue grip panels and a worn tan finish. Compared to the M45 MEUSOC, the 1911 TACOPS does slightly less damage than the M45, but has the benefit of having one more round due to its eight-round magazine (and a total of nine with one in the chamber).

CZ P-10 C

The CZ P-10 C is one of the sidearms available to the GSUTR and Metropolitan Police Service Defender Operator Clash added in Year 3 Season 3 Operation Grim Sky, as well as Secret Service operator Warden added in Year 4 Season 2 Operation Phantom Sight. It features a permanently-attached SIG ROMEO1 red dot sight like the PR-15 Ragun, and a blue flat-faced HB Industries aftermarket trigger.

AMC Auto Mag

The two Moroccan GIGR Operators added in Operation Wind Bastion (the Attacker Nomad and the Defender Kaid) both have access to an AMC Auto Mag as their sole sidearm option. It goes by the rather generic moniker ".44 Mag Semi-Auto" in-game, and is fitted with Duane Short wood grips and a permanently-affixed low-power pistol scope, the only sidearm in the game to have a sight that grants x2.5 magnification.

The Auto Mag is a rather bizarre choice; if the pistol's heavy weight, low magazine capacity, large size (especially with a scope mounted), and sharp recoil don't make it an impractical option for martial use (not unlike the Navy SEALs' equally ridiculous Desert Eagle Mark XIX), then its significant rarity (and correspondingly high price tag) and nigh-on unobtainable proprietary ammunition certainly do. That said, all these factors convinced Ubisoft that the gun is an unparalleled work of craftsmanship and turned it into a pocket DMR.

High-Standard-manufactured Auto Mag - .44 AMP
The Auto Mag in the inspection screen. Note that the barrel seems to be slightly longer than the one in the reference image (having 4 vents instead of 3), but is not as long as the real gun's alternate 10 inch barrel option, which also lacks the ribs. The barrel seems closer to that of the .22 LR Baby Auto Mag in some respects.
Nomad points her Auto Mag towards the heavens, giving a good look at its well-polished finish.

When you've only got seven rounds to a magazine, that extra one in the pipe can make all the difference. Especially when each one hits with the force of a small train.
Ditching an empty magazine (not a wise choice - if the gun itself is unobtainium, then extra mags are its rarest isotope, Un-562).

CZ P-09 in CAA Tactical RONI-G2

Mozzie, the Australian Defender added in the Operation Burnt Horizon expansion and Aruni, the Thai Defender added in the Operation Neon Dawn expansion, can wield the "P10 RONI" as a primary weapon option under the submachine gun category; despite having "P10" in the name, it is actually a CZ P-09, converted to full-auto and somehow mounted into a CAA Tactical RONI-G2 carbine conversion kit meant for Glock pistols. It lacks the spare magazine holder and the foregrip is absent by default, though the foregrip is reattached with the Angled Grip and Vertical Grip attachments. It is fitted with Magpul MBUS Gen 2 sights and can be equipped with Battlecomp 2.0 flash hider. Initially, it had a unique holographic sight modeled after the Vortex Razor UH-1, this sight has since been given to every operator.

Sphinx SDP Compact Duty

The pistol sidearm option for both Australian SASR operators added in the Operation Burnt Horizon expansion is the Sphinx SDP Compact Duty with a "Krypton" (OD green) frame, going by the name "SDP 9mm" in-game. The pistol was also later given to SFG operator Sens in Operation Vector Glare expansion.

Revolvers

Smith & Wesson Model 586

The base game's lone revolver, the Smith & Wesson Model 586 is available to the French GIGN. It appears as the "LFP586". This weapon is likely standing in for the Manurhin MR-73 revolver, which is used in real life by the French GIGN. Compared to their FNP-9, the Model 586 offers substantially greater stopping power per shot, but requires prime shot placement and well-timed reloads to offset its stout recoil and low capacity. The only accessory available to the 586 is a laser aiming module mounted onto the trigger guard.

Oddly, the revolver has different empty and non-empty reload animations; on a non-empty reload, the user will press the cylinder release with their right thumb and push the cylinder with their left hand from the right side, whereas on an empty reload, they will press the cylinder release with their left thumb.

Taurus 4510PLYFS

The Taurus 4510PLYFS is a sidearm option for Italian GIS Operators Maestro and Alibi GIGN operator Doc, Nighthaven operator Grim, GIGR guest operator Oryx and unaffiliated operator Fenrir. It is a .410 shotgun revolver that holds 5 rounds. In Siege, it is called the "Bailiff 410", a play on the real weapon's "Judge" moniker. It comes equipped with a fixed ROMEO1 reflex sight, just as some pistols do.

Rather weirdly, there are different animations for non-empty and empty reloads (despite there being no open/closed bolt tracking on this gun nor the need to chamber anything), with the non-empty reload animation ending with a very un-Tom Clancylike flick to shut the cylinder, and the empty reload ending with the operator pushing it shut and giving it a spin, Gordon Freeman-style.

The Chiappa Rhino 40DS, referred to in-game as the "KERATOS .357" ("keratos" being Greek for "horn"), was added in Operation Para Bellum, and can be used by GIS Operators Alibi and Maestro, and NIGHTHAVEN Operator Wamai. It is rather bizarrely depicted as being capable of using a suppressor; with the exception of the Nagant M1895, revolvers fitted with suppressors serve essentially no purpose, as the gases that escape through the gap between the cylinder and barrel would more or less completely negate any noise-reducing effects that the suppressor would otherwise have. This mistake is made even more bizarre by the fact that the game's three other revolvers are both correctly shown as being unable to use a suppressor.

The Rhino's hammer-shaped cocking lever incorrectly cycles when the gun is fired; the Rhino's actual hammer is internal.

Smith & Wesson Model 629 Stealth Hunter

The Smith & Wesson Model 629 Stealth Hunter was added to the game as the signature sidearm of mercenary Keres Legion leader and former Rainbow member Deimos, introduced in Operation Deadly Omen. Appearing as the ".44 Vendetta", it is the only sidearm usable by Deimos, comes with a permanently mounted short-range scope, and has only a single attachment option, a laser sight (which, like the 586, is mounted to the trigger guard despite the presence of a front rail section). The description states it is custom made by Deimos, and indeed has some differences from the real thing, such as barrel ribbing, a ported muzzle similar to that of the Smith & Wesson Model 500, and a flat, square cylinder release.

In game, it is portrayed with absurdly low recoil despite its stated .44 Magnum chambering, being more in line with .22 LR than anything. The revolver is depicted as single-action, with the draw animation having him pull back the hammer. However, the hammer is only cocked when the revolver is hip-fired and the weapon has a very high rate of fire, almost as fast as the player can press the fire button on their controller or mouse. The reload speed is also noticeably faster than the other revolvers in the game. It is also the only weapon Deimos can use when he activates his unique gadget, the DeathMARK Tracker.

Submachine Guns

This section primarily covers two in-game categories, Submachine Guns and Machine Pistols. As they're meant to fight in close quarters, SMGs are primarily used by the defenders, although a few are available to attackers. None are used by AI enemies in Terrorist Hunt.

FN P90 TR

The FN P90 TR is available to the GIGN Defenders and AFEAU Operator Solis. It can be equipped with an extended barrel that turns it into a fully-automatic PS90 carbine. Its one of the few SMGs capable of using an ACOG sight.

Heckler & Koch MP5 MLI

The Heckler & Koch MP5 MLI is also usable by the GIGN Operators Doc and Rook, and ITF Operator Melusi. It appears as the "MP5". Its one of the few SMGs capable of using an ACOG sight.

Trivia: GIGR guest operator Oryx could formerly use the MP5 MLI until Operation Neon Dawn had him swap the MP5 with Melusi's Jianshe.

The Heckler & Koch MP5K-PDW is available in the game. Its used by SAS Operator Mute, NIGHTHAVEN Operator Wamai, and the updated Defender Recruit. Unlike the MP5 MLI and MP5SD, it is not capable of using an ACOG sight.

Heckler & Koch MP7A1

The Heckler & Koch MP7A1 is issued to the GSG-9 Defender Bandit and unaffiliated Operator Fenrir. It has a 30-round magazine capacity despite being modeled with the 40-round magazine. At launch, the charging handle was for some reason modeled to be permanently in its pulled back position, even visible on HUD icons; this error was fixed in the Operation Black Ice update. In the Dust Line update, the carabiner clipped to the rear sling mount was removed in favor of a "charm" mount instead. A special version was added in Year 5 Season 3 Operation Shadow Legacy, available to Attacker Zero.

Heckler & Koch UMP45

The Heckler & Koch UMP45 is used by the FBI Defenders. The charging handle incorrectly locks back on its own when the magazine is emptied, similar to the MP5 in Far Cry 3 and Far Cry 4. It has a three-round burst mode; the real UMP45 only has a two-round burst mode.

PP-19-01 Vityaz

The PP-19-01 Vityaz appears as the "9×19VSN" and is available to Spetsnaz Defenders Tachanka and Kapkan, as well as unaffiliated Defender Azami. It is heavily customized with Zenitco furniture, including a B-13 optic mount that remains permanently on the weapon, optic on or off. VSN quite likely is an abbreviation of "PP-19-01 Vityaz-SN", which is a variant of the Vityaz with a railed dust cover and no side rail, but this very clearly has a smooth dust cover and a side rail with the B-13 optic mount on it, making it just an original PP-19-01 Vityaz.

MAC-10

A MAC-10 with the upper receiver of a MasterPiece Arms MPA10SST appears as the "SMG-11," as in Watch_Dogs. The shape of the ejection port denotes it as the .45 ACP version. It is one of the few secondary SMGs available, and is used by all SAS defenders, as well as Peruvian Operator Amaru and Colombian Operator Solis. The Recruit defender can also use the MAC-10.

The weapon uses a 30-round magazine, but for balancing reasons it only has half that at 16 rounds.

Infamously, the MAC-10 used to be able to use a magnified ACOG as an optic option, with the weapon often paired with Smoke on defense. The high damage of the MAC-10 along with its low recoil prior to a later SMG recoil rework resulted in the MAC-10 becoming frequently decried as overpowered and referred to as a "pocket sniper". In a controversial move, Ubisoft removed the ACOG from the MAC-10 in November 2016 during Operation Red Crow.

"SMG-12"

The "SMG-12" is a sidearm available to the Korean 707th SMB Operators and US Secret Service Operator Warden. It appears to be a further development of the SAS's "SMG-11". It appears to have the general receiver design of the MasterPiece Arms MPA935SST, the trigger guard of the MasterPiece Arms MPA930DMG, a wire stock, and a large KeyMod foreend with rail bits. It was initially integrally suppressed, although this feature was removed in the first Year 3 patch.

While weaker than the SMG-11 due to its smaller cartridge; it has the benefit of having a 32-round magazine and the ability to use an angled foregrip to increase ADS speed.

Magpul FMG-9

The Magpul FMG-9 is available in the game, and is used by SAS Operator Smoke and the SAS Defender Recruit. It has also been available to Jaeger Corps Operator Nøkk who is on the attacker's side, making it the second available primary SMG available to Attackers, after Jackal's UDP-9.

The weapon performs similarly to the MP5K, but with worse damage drop-off at range. A strange fact when you consider that the FMG-9 has a longer barrel than the MP5K.

C1 Submachine Gun

The C1 Submachine Gun, the Canadian variant of the Sterling Mk.4 Submachine Gun, has been available in the game since the Operation Black Ice expansion was released. It is referred to as the "9mm C1", and is exclusive to the JTF-2 Defender Frost. The in-game weapon seems to be modeled after the MGC replica for the C1, and includes its unique round front sight. In reality, the C1 is long out of service, a more appropriate choice would have been an MP5 or FN P90, but both are already in use by other operators in game and Siege wouldn't start recycling weapons until year 4.

The weapon can be equipped with a suppressor or extended barrel that turns it into a carbine. Additionally, its one of the few SMGs that can't use a vertical grip and can only use an angled foregrip (although due to its low recoil and slow firing rate; it still remains stable even at full auto).

Prior to the Skull Rain DLC, Frost used to wield her C1 SMG improperly by gripping the magazine, which is a great way to damage the magazine and the well. Note the rail mounted onto the weapon; this is a fictional version of the original NATO standard rail (that got replaced by the Picatinny rail) present on other guns in the game, such as the L85A2. The C1 does not use any sort of rail system on top of the receiver, and this fictionalised rail is thinner and flimsier-looking than the real thing.

SIG-Sauer MPX

The SIG-Sauer MPX is one of the weapons available to the Navy SEAL operator Valkyrie, Secret Service operator Warden and Portuguese DAE operator Tubarão, simply referred to in-game as the "MPX". It is a cross between the prototype version and the Gen 1 model, as it has the left-side receiver components of the former, but with the right-side receiver components and the 8" barrel. It is also fitted with an early version of the MPX Gen 1's collapsible stock.

She then turns the gun over to yank the charging handle.
With determination, Warden outdoes Valkyrie with his MPX manual-of-arms. Note how the safety and the upper part of the magwell are those of an MPX prototype, in contrast to the right side shown below.
Neither one of them has quite figured out how to use the bolt release paddle though. In Warden's unique reload animation, the charging handle is pulled back only about half the distance it would need to be in order to chamber a round in reality. As additional trivia, Warden has unique sprint animations for all of his weapons, different from the standard gun to the side sprint animation. For most weapons, including the MPX, he sprints with the gun in one hand, pointed upwards. For his other primary, the M590A1, he sprints with the gun sideways and tilted. Here we can see the ejection port, mag release and ambidextrous bolt catch of an MPX Gen 1.

Beretta PM12S

The Beretta M12, with the stock extended, is one of the weapons available to the BOPE Defender Caveira. As with other open bolt weapons in-game, it is incorrectly portrayed as having an additional round in the chamber.

The weapon can be equipped with a long carbine-length barrel.

Heckler & Koch MP5SD2

The Heckler & Koch MP5SD2 is one of the weapons available to the SAT Defender Echo, simply referred to in-game as the "MP5SD". The weapon performs similarly to the MP5 MLI, but is equipped with a built-in suppressor that does not reduce its damage.

Minebea M-9

The Minebea M-9 is one of the few secondary SMGs available and usable by Japanese SAT Operators Hibana and Echo, also later given to STAR-NET Aviation Operator Thunderbird and as part of balancing measures, later given to the Spetsnaz Operators Glaz and Tachanka. It is referred to as the "Bearing 9".

Angstadt Arms UDP-9

The Angstadt Arms UDP-9 was added to the game with the Operation Velvet Shell expansion. It is referred to as the "PDW9", and is used by the GEO operator Jackal and later NIGHTHAVEN Operator Osa, initially the only primary SMG available to the Attackers until the introduction of Nøkk who is armed with an FMG-9. It feeds from KCI 50-round 9mm Glock drum magazines (also known by other imported rebranded names such as SGM Tactical drum mags) and has a Rainier Arms ambidextrous charging handle. It formerly had an incorrect 3-round burst option; this was later removed.

KRISS Vector

A Gen I / Gen II hybrid KRISS Vector is available in the game with the Operation Velvet Shell expansion. It is referred to as the "Vector .45 ACP" (the same name it goes by in several other Ubisoft games since Far Cry 3), and is available to GEO operator Mira and Mexican Fuerzas Especiales operator Goyo. It holds 25 + 1 rounds, and has an additional 2-round burst firing mode like in reality.

"V308"

A fictional 7.62x51mm NATO version appears as the primary choice for GIGN CBRN specialist Lion, of the Operation Chimera expansion. It bears a strong resemblance to the sci-fi weapon design "HK G56" by concept artist AlexJJessup, and uses an X Products type drum magazine, similar to the X-91 already used by the G8A1 in-game, though this one is adapted for the fictional .308 Vector magwell and is more correctly proportioned. It is referred to as the "V308".

Jianshe CS/LS2

The Jianshe CS/LS2 is one of the weapons available to the SDU Defender Lesion and was later to given to (unofficial) GIGR guest operator Oryx. It is referred to as the "T-5 SMG", and like several other open bolt guns is depicted with an incorrect closed bolt operation in Siege.

Trivia: ITF Operator Melusi could formerly equip the Jianshe until Operation Neon Dawn swapped her Jianshe with Oryx's MP5 MLI.

CZ Scorpion Evo 3 S1 Carbine

The CZ Scorpion Evo 3 S1 Carbine, a civilian variant of the Scorpion Evo 3 A1, is one of the primary weapons available to the GROM Defender Ela. Unlike its real-world counterpart, (a civilian semi-auto carbine), it fires full-auto in-game like a standard Evo 3 A1; interestingly, it is modeled with the correct fire selector for such a weapon, rather than the 2-position safe-semi selector of the S1. It uses magazines fitted with CZ Custom magazine extensions; this initially gave them a correct (and, as many players complained, completely overpowered) capacity of 50 rounds, but this was later reduced to 40, for balance reasons. It also sports a HB Industries THETA trigger and charging handle in a bright green color, and the extended receiver features Picatinny rails on the M-LOK slots.

The Beretta Mx4 Storm is a submachine gun available exclusively to Italian GIS Defender Alibi, who was added during Operation Para Bellum.

Brügger & Thomet MP9-N

The Brügger & Thomet MP9-N is one of the sidearms available to SCO19 (and GSUTR) operator Clash (her primary weapon is the CCE Shield, meaning that she only has firearms as secondary options), added in Operation Grim Sky and NIGHTHAVEN operator Kali. It is referred to as the "SPSMG9", uses 20-round magazines, features a permanently attached red dot sight, and was initially locked in two-round burst fire mode.

A future update removed the two-round burst and allowed it to fire on full-auto, making it a true secondary machine pistol.

Steyr AUG A3 9mm XS

The Steyr AUG A3 9mm XS is one of the weapons available to the Moroccan GIGR Defender Kaid added in Operation Wind Bastion; it is referred to simply as the "AUG A3". While it is modeled with a 32-round magazine, it bizarrely has a capacity of 31+1 in-game.

Colt 9mm Submachine Gun (R0991)

The Colt 9mm Submachine Gun, specifically the R0991 model, is available as a primary option for the Australian Defender Mozzie added in Operation Burnt Horizon and later given to Defender Recruit Sentry as part of Operation New Blood. It is modeled with a fixed stock, similarly to the civilian R6430 model. It is referred to in-game as the "Commando 9", and holds 25+1 rounds despite being modeled with a 32-round magazine. Bizarrely, it is currently incorrectly classified as an assault rifle, like the HK416-C (and unlike the K1A), despite it being quite obviously a submachine gun both visually and performance-wise.

Render of the "Commando 9" from Mozzie Cosplay Guide. Note the rail-mounted carry handle, fixed stock, round handguard, and extra rail segments on the handguard. The stock, lower receiver, and pistol grip also feature a rather worn coat of camouflage paint; this appears to be at least partially inspired by the finish applied to wartime Owen Guns, fittingly enough.

During empty reloads, on the other hand, Mozzie twists the gun to the right as he dumps the old magazine; this gives a good view of the right side of the receiver, showing that, while it does correctly have an SMG-type brass deflector, it also bafflingly has a standard rifle-style brass deflector behind it, and a forward assist behind that, possibly suggesting that a standard 5.56mm AR variant was used as a reference/basis for the model. The open ejection port furthers this idea with its view of the rifle-type locking lugs visible in the back of the barrel extension (Colt's 9mm subguns are all straight blowback, and thus lack these); to top it all off, Mozzie's consistently nonexistent trigger discipline means that he's not even hitting the magazine release.

IMI Uzi

A stylized IMI Uzi was added in Y6S4 Operation High Calibre as the "UZK50GI" as the Irish Garda EDU Defender Thorn's signature primary weapon. It is rechambered in .50 GI, has a high-powered destruction profile, and holds 22 rounds, with an incorrect +1 chambering.

Rifles and Carbines

These weapons are mostly usable by Attackers in Multiplayer. This large category of weapons is also sub-divided into Assault Rifles and Marksman Rifles in-game, the latter of which all fire semi-auto only.

AK-12

The 2012 prototype variation of the AK-12 is issued to operators Fuze and Ace. The Spetsnaz Recruit had access to the AK-12 in older versions of the game.

Enfield L85A2

The Enfield L85A2 is available in the game, and issued to all SAS Attackers and the Recruit class. It is fitted with a long, quad-railed Daniel Defense handguard.

It was also, most bizarrely, the primary weapon of the "White Mask" terrorists in the Terrorist Hunt mode. Exactly why they chose to use a somewhat uncommon assault rifle, not exported in wide numbers, with near-unobtainable spare parts, and plagued with a variety of design issues even after its improvement as a service weapon, is as much as a mystery as the White Masks' relevance in Siege in general.

Note the rail underneath the carry handle; this is a fictional version of the original NATO standard rail (that got replaced by the Picatinny rail) present on other guns in the game, such as the C1 SMG. The SA80 does use this style of rail instead of the Picatinny rail, but it is thinner and flimsier-looking in-game.

FAMAS F1

The FAMAS F1 appears in the game as the "F2" and originally incorrectly held 30 rounds in 25-round magazines. The magazine capacity was changed to 25 during a mid-season balance patch in Y4S3, nerfing the gun while making its magazine capacity accurate to real life. It is only available to Operator Twitch, after the Recruit rework removed the faction-based Recruit system.

Heckler & Koch G36C

The Heckler & Koch G36C is available in the game, and used by FBI SWAT operator Ash and REU operator Iana.

The gun was frequently overlooked due to its complete inferiority to her other weapon, the R4-C, until a later patch made it that the G36C is the only gun in Ash's arsenal that can use an ACOG optic (which grants a very valuable x2.5 view magnification) before the R4-C received the ACOG once more in Operation Deadly Omen.

Heckler & Koch HK33A2

The Heckler & Koch HK33A2 appears as the "AR33", and is used by SAS Operator Thatcher and FBI asset Flores. It uses a 30-round magazine, though it only holds 25 rounds. It has a permanently attached optic rail, a rail on the bottom of the handguard, and a "charm mount" was on the left side of the stock, above the stock pins, but was updated to be on the rearward most claw on the optic mount. The rear sight is removed when using optics.

Heckler & Koch HK416C

The Heckler & Koch HK416C is appears as the "416-C Carbine". Prior to the "White Noise" update that added the Daewoo K1A for Vigil, it was the only assault rifle usable on the Defender's side; issued to Jäger and the original GSG-9 Recruits. Long considered one of the best weapons for Defenders, it was the target of multiple nerfs, including one that took its magazine capacity down from 30+1 to 25+1.

The weapon can be equipped with a 14.5 inch extended barrel.

Heckler & Koch HK417

The Heckler & Koch HK417 is available to Twitch, GIGN CBRN specialist Lion and SFG operator Sens. It is intended to be used as a DMR, as it is restricted to semi-auto only. It is also modeled with a 20-round magazine, which is rendered solid instead of transparent, but at release it had the in-game capacity of only 10 rounds; this was buffed and fixed to the correct 20 rounds in Operation Ember Rise.

Remington R4-C

A Remington R4-C appears simply as the "R4-C" and is available to FBI Operator Ash and South Korea's 35th Commando Battalion Operator Ram in the upcoming Operation Heavy Mettle expansion. It is modeled with a Magpul MOE pistol grip, CTR buttstock, and Remington RAHG modular forend with rail sections permanently installed. The weapon's charm mount is located in the middle of the receiver, close to the top rail.

SIG SG 552

The SIG SG 552 is appears as the "552 Commando". Like in previous games, it has a 30 round magazine capacity despite being modeled with the 20 round magazine. It was also seen in terrorist hands in the Terrorist Hunt mode. The SG 552 is used by GSG-9 Attacker IQ and NIGHTHAVEN Attacker Grim.

SIG-Sauer SIG556xi SWAT

The SIG-Sauer SIG556xi SWAT with a full-auto lower and a 16" barrel is available to FBI attacker Thermite and NIGHTHAVEN attacker Osa. When firing, and when the bolt locks back after the last shot, the bolt does not fully recoil backwards, and instead stops at the point where the ejection port/charging handle slot narrows; apparently the developers mistook the narrowed charging handle slot as a fixed part of the receiver.

Trivia: in the "Inside Rainbow" trailer series showcasing the CTUs, Glaz is seen using the weapon in the the SAS, FBI SWAT, and GIGN trailers. The model is slightly different, with more segments on the handguard and R4-C-styled diamond iron sights, and is also incredibly broken - it sounds like an OTs-03 when fired, and Glaz's hand isn't even on the trigger when firing. He got the proper SVU model by the release of the GSG-9 and the Spetsnaz trailers.

Steyr AUG A2

The Steyr AUG A2 appears under the name "Aug A2", the developers seemingly not realizing that AUG is an acronym and should be capitalized accordingly. It is available in the game to the GSG-9 operator IQ and NIGHTHAVEN operator Wamai and was occasionally seen in terrorist hands in the Terrorist Hunt mode.

Colt Model 933

A Colt Model 933 with the carrying handle removed, a KAC RIS handguard, Colt Canada-type M4 stock, and using Magpul PMAGs with Ranger plates has been available for JTF-2 operator Buck since the Operation Black Ice expansion was released. It is referred to incorrectly as the "C8 SFW", but is identifiable as a 933 by its 11.5" barrel. It also incorrectly has a cut in the barrel for an M203 grenade launcher.

It is equipped with a M26 Modular Accessory Shotgun System, which is actually Buck's special gadget, the "Skeleton Key". Details of it can be seen below. The Team Deathmatch and free-for-all Deathmatch game modes added much later removes the ability to use operator abilities, and rather than giving Buck an empty shotgun, it actually removes the M26 from the weapon entirely. The M26-less rifle can also be seen in the loadout menu, though exclusively in the overview section, as actually clicking on it to customize brings the M26 back.

C1A1

The C1A1, the Canadian variant of the L1A1 SLR, is Buck's second primary weapon choice from the Operation Black Ice expansion. It is referred to as the "CAMRS", and is fitted with an L1A1 SLR's synthetic stock and handguard. Like the "C8-SFW", Buck's special gadget the "Skeleton Key" (a M26 Modular Accessory Shotgun System) is attached to the weapon, details of which can be seen below. The C1A1 without the skeleton key is available to COT operator Brava from the Operation Commanding Force expansion.

It is only capable of semi-auto fire, accurate for a C1A1.

FN SCAR-H CQC

The FN SCAR-H CQC has been available in the game since the Operation Dust Line expansion was released, for Navy SEAL operator Blackbeard. It is referred to as the "Mk17 CQB".

The weapon is powerful, but is plagued by having the slowest ADS speed of any assault rifle in the game and extremely high recoil, leading to many in the community labeling it one of the worst primary weapons in the game.

Knight's Armament SR-25

The Knight's Armament SR-25 Enhanced Combat Carbine is the DMR option for Blackbeard and one of the two weapons included in his kit. It was later made available to FBI asset and questionable rogue Flores. The Crane stock has been replaced with a Magpul UBR stock and Blackbeard has custom clips mounted on the handguards of his SR25 to allow the attachment of his rifle shield.

It is a generally average but lackluster gun in comparison to others.

DSA SA58 OSW Carbine

A DSA SA58 OSW Carbine is the main battle rifle available to BOPE Operator Capitão and COT Operator Brava (who happens to be Capitão's cousin), under the name of "PARA-308". It has a worn tan finish and holds 30 rounds per magazine; the magazine depicted in-game is too short for that, but is also too long to be 20-rounder - 25 rounds would be a good guess.

Colt Canada C7

The Colt Canada C7 is used exclusively by GEO Operator Jackal who was added with the Operation Velvet Shell DLC. The weapon in-game is modeled after the C7NLD, an officially dubbed, custom variant of the C7 used by the Armed Forces of the Netherlands. Along with the Dutch handguard, it is fitted with a Magpul PRS, uses PMAGs with Ranger Plates, and has the same charging handle as the UDP-9. It is named the "C7E" in-game, and is incorrectly depicted as having both fully-automatic and burst-fire modes.

Daewoo K1A

A customized Daewoo K1A is available for 707th SMB Operator Vigil with the Operation White Noise expansion. It is referred to as the "K1A" and is classified as a submachine gun; while this isn't correct from a technical standpoint, it is at least correct in the sense that that's how the Korean military classifies it. The gameplay seems to go with the SMG route too, having a damage and recoil profile more similar to other SMGs than the assault rifles.

Beryl M762

A heavily customized Beryl M762 is the primary choice for GROM operator Zofia of the Operation White Noise expansion, named simply as "M762". It is fitted with the Midwest Industries Extended Handguard, a Hera Arms CQR stock, and a railed dust cover in lieu of its standard rail assembly. The assortment of customizations is primarily inspired by a photoshopped AK reported by The Firearms Blog, which is an AK-103-lookalike with the Midwest Industries Gen 1 SS-Extended Handguard with the Hera Arms CQR stock photoshopped in.

Saritch

A compact version of the Saritch design concept is the primary choice for Spetsnaz CBRN specialist Finka, of the Operation Chimera expansion and later STAR-NET Aviation Operator Thunderbird in the Operation North Star expansion. In-universe, the Saritch appears to be a prototype weapon. Where in reality, the design is one conceived military version of the Saritch proposed by its designer but never mocked up, with 30-round magazines, automatic fire and a compact barrel; the in-game model resembles the medium-length 622mm-barrel version shown in the weapon designer's concept arts. A right-facing ejection port has been added to the weapon, and the forearm is replaced with a set of underbarrel rails. It is referred to as the "Spear .308".

M4A1 Block II

Available for SFOD-D (and GSUTR) Operator Maverick of the Operation Grim Sky expansion and Attacker Recruit Striker as of Operation New Blood, a carbine indexed as the "M4" appears to be a customized M4A1 Block II. It features a Daniel Defense MK18 RIS II 9.5 inch railed handguard and a 12.5 inch barrel instead of the usual 14.5 inch barrel, along with a tan Command Arms UPG16 modular pistol grip (a copy of the Fab Defense/Mako AG-43), rail covers, and a standard 6-position M4 stock. The weapon is marked "M4A1 Carbine" on the left side of the mag-well where the usual roll marks would be. Equipping the "M4" with the Heavy Barrel attachment gives it a longer 16-inch aftermarket pencil barrel. Attaching this would technically make it a heavily modernized Colt Model 653 instead of a proper Block II.

It incorrectly features semi-auto, three-round burst, and fully automatic fire modes, even though it has an M4's Safe/Semi/Burst fire selector, while being marked as an M4A1. Additionally, the developers forgot to model a gas block onto the standard or extended barrel, so in reality Maverick's using a bolt-action M4 that's only capable of automatic fire through the power of video game magic.

It has a unique suppressor model, which is wrapped in lots of cloth like Caviera's Luison's suppressor, to help remove the mirage from when the can is hot and make it safer to re-tighten it. Equipping the compensator gives it a unique XM177-style moderator.

Alexander Arms .50 Beowulf

The Alexander Arms .50 Beowulf is available for the SFOD-D Attacker Maverick with the Operation Grim Sky expansion. It is referred to as the "AR-15.50", and is correctly semi-automatic. It is fitted with a Mako Group Recoil Reducing GL-Shock stock, a Mako Group MWG (mag well grip), and a Magpul BAD Lever (which is never used, Maverick instead pulling the charging handle on empty reloads).It was also later given to DAE operator Tubarão in the Operation Deep Freeze expansion.

The weapon used SureFire 60-round quad-stack magazines at release, but only holds 10 rounds in gameplay - not that this really matters, since the internal geometry of the SureFire magazine would render .50 Beowulf rounds unable to fit anyways. The Operation Burnt Horizon update apparently acknowledged this, replacing the magazine with a more sensible 30-rounder, fitted with a Magpul Ranger Plate; this also fixes the capacity issue, since 30-round STANAG magazines can fit only ten .50 Beowulf rounds.

"AK-74M"

The "AK-74M" is an assault rifle available for GIGR operator Nomad of the Operation Wind Bastion expansion and later for Deimos as his alternate primary. Instead of being an actual AK-74M, the in-game weapon the appears to be an AKM customized with Magpul MOE pistol grip, stock, hand guard, and a rail mount. Telltale signs of the in-game weapon model being based on an AKM is its ribbed dust cover, original slanted gas block, and its magazine being a waffle-pattern 7.62x39mm magazine (that holds 40 rounds) instead of 5.45x39mm that the AK-74M actually uses.

The right side of the in-game weapon features a white piece near the stock, which exists on the real AK-74M as a component of its side-folding stock. Despite this, the in-game weapon does not have a folding stock, and even lacks the corresponding button on the other side of the receiver for the AK-74M's folding stock.

More bizarrely, the lower receiver is marked "WASR-10 Cal. 5.45×39mm"; the WASR-10 is indeed an AK variant, but is 7.62x39mm like the AKM, and is also semi-automatic only while the in-game weapon is select-fire. The in-game receiver also most definitely isn't based on a WASR-10 since it has standard AK dimples which the WASR-10 lacks.

Just to confuse matters further, the Operation Burnt Horizon update replaced the 7.62x39mm magazine model with a 5.45x39mm one, appropriate for an actual AK-74M, but not for anything else that the gun is based on.

Beretta ARX-200

The Beretta ARX-200 is available for the GIGR attacker Nomad and REU operator Iana. In comparison to Nomad's frankensteined AKM, the ARX-200 does more damage, at the cost of having higher recoil and lower magazine size.

"SC3000K"

An FN F2000 Tactical with a slightly modified design and rechambered in .300 Blackout was added in the game in the Operation Shadow Legacy expansion as the "SC3000K". It is used by the Operator Zero, aka Sam Fisher from the Tom Clancy's Splinter Cell series. The weapon itself is a nod to the many F2000s (many times with fictional modifications) used by Sam Fisher throughout the Splinter Cell series, all of them having the fictional series name of "SC-number-K" (starting from the "SC-20K" in the original Splinter Cell).

Machine Guns

With exception to Tachanka's DP-28 and Maestro's CETME Ameli, Machine Guns are issued only to Attackers. As with some SMGs, most open bolt machine guns incorrectly track +1 in the chamber.

Degtyaryov DP-28

The Spetsnaz operator Tachanka's primary weapon is a DP-28, also known as the DP-27. At the release of the game, the DP was Tachanka's gadget, mounted onto tripod and able to be manned by anyone, even by enemies in unfortunate situations, and his primary weapons were the Vityaz and Saiga. In this tripod-mounted form it was called the "RP-46" in game, though this is the designation for the belt-fed, pistol-gripped version of the DP. Tachanka himself referred to it as the "DP-28." Its magazines hold an erroneous 70 rounds, and incorrectly do not rotate as the weapon fires. During its life as a mounted weapon, it incorrectly tracked the round in the chamber, but after being reworked into his primary weapon, it's correctly depicted as open-bolt, and the extra round was given to Tachanka's ammo reserve.

In its original form, the DP-28 was widely considered an extremely weak gadget, resulting in Tachanka being regarded as one of the weakest Operators in the game (conversely also earning him the ironic nickname and memetic badass status of "Lord Tachanka"). While dealing high damage, the mounted machine gun was extremely situational and required careful placement and quite a bit of luck in order to be used successfully. It was also (comparatively) very slow to both set up and take down. Furthermore, the machine gun could only turn a maximum of 60 degrees in either direction.

A patch released in December 2016 added a reinforced glass shield to the turret (modeled after this particular shield, and marked with the Russian word for "Lord" acknowledging the Lord Tachanka meme), making its usage somewhat more viable. In Operation Blood Orchid, it was changed so that Tachanka kept the magazine loaded in the weapon when moving it instead of unloading and loading it every time, making it faster to move around.

The 2020 October update made the DP-28 man-portable, as Tachanka's new primary weapon, as part of a rework to Tachanka's kit.

Heckler & Koch HK23/HK13 Hybrid

A hybrid of the 5.56mm belt-fed Heckler & Koch HK23 and the 5.56mm mag-fed Heckler & Koch HK13 appears in Rainbow Six Siege. The magazine well is a key feature of the HK13, but the receiver design, with its longer ejection port and a large, tubular brass deflector, is almost never found on the mag-fed HK machine guns, and instead comes from the belt-fed HK machine guns like the HK23. It has a G3 rear sight and added rails.

It appears under the name "G8A1", the German designation of the 7.62mm mag-fed Heckler & Koch HK11, even though its magazine well is rather clearly in 5.56mm, appearing more or less identical to the one on Thatcher's HK33. Despite the magazine well, the magazine used are 7.62mm X Products X-91 50-round drum magazines, apparently scaled down to fit into the 5.56mm magazine well.

The weapon is available in the game for IQ and Peruvian Operator Amaru introduced in Year 4 Season 3 Operation Ember Rise.

M249 SAW

The second option for BOPE attacker Capitão and Attacker Recruit Striker is the M249 SAW, appearing under its real name as simply "M249". It has a newer FN Minimi Mk 3 collapsible stock and sports a worn beige finish by default, similar to his SA58 OSW. Until Operation Blood Orchid, it incorrectly tracked a round in the chamber. The reworked Recruit also has access to the belt-fed SAW.

Australian attacker Gridlock added later in Operation Burnt Horizon has a near-identical M249 as a primary weapon option, albeit without the beige finish, which for some reason gets a new designation of "M249 SAW". Hers somewhat bafflingly uses a 60-round SureFire quad-stack magazine shoved into the emergency STANAG magazine well, rather than a belt; while this isn't strictly impossible, the M249's magwell is notoriously unreliable, and belts are preferred whenever possible. It previously had access to a unique 3x scope attachment, which works like the pistol scope on the Auto Mag Pistol, but this was removed in a September 2020 patch.

When reloading from empty, the charging handle on Gridlock's M249 incorrectly springs back forwards after she pulls it back, while Capitão's M249 is correctly animated with him pushing the handle back forwards manually.

QJB-95

The QJB-95 is available in the game with the Operation Blood Orchid expansion. It is indexed as the "T-95 LSW", and is usable by the SDU attacker Ying. The weapon's description states that it has been custom made to fire 5.56mm rounds, even though the weapon model is clearly based on the 5.8x42mm version. The QJB-95 is also modeled with several upgrades from civilian Type-97 rifles, such as the flat-top upper, enhanced trigger group, and lower handguard upgrades, reflecting its "custom" nature.

Krytac Trident LMG-E

The same airsoft gun based on the Ares Shrike from Ghost Recon: Wildlands appears in Siege under the designation of "LMG-E". The "LMG-E" is used by GROM operator Zofia and 35th Commando Battalion Operator Ram.

CETME Ameli

The CETME Ameli is added in Operation Para Bellum as the "ALDA 5.56". Being a primary option for Defense Operator Maestro, it was the only portable LMG available to Defenders, until Tachanka's rework made his DP-27 mobile.

Attaching a new 80 round belt box onto the gun. There are a few things unusual with this belt box: the CETME Ameli only has 100 or 200-round belt boxes in reality, and the in-game 80-round belt box has a similar shape to the 200-round one, but is much smaller and slimmer. 100-rounds would be a good guess. The in-game belt box also opens to the right rather than to the left like on the real belt boxes. Due to the right-sided belt box opening, Maestro uses an unorthodox process where he locks the first round in position (as pictured here) and then pulls the box out to attach it to the left side of the weapon, as opposed to the standard "attach the belt box first and then pull out the belt" procedure.

Shotguns

Shotguns are available to both sides in Multiplayer. Given the game's emphasis on micro-destruction, they make great assets in "redecorating" the interiors throughout the game's levels, except for the ones that fire slugs.

Benelli M4 Super 90

The Benelli M4 Super 90 is available in the game, and goes by its US Military designation of M1014. Although in-game, the M4 holds 7+1 rounds, it is modeled with a 4-round civilian magazine-tube. The Benelli M4 is usable by every FBI operator except Ash, and Norwegian Nighthaven operator Ace.

FABARM SDASS Compact

A FABARM SDASS Compact with the ghost ring sights of the "Tactical" model appears as the "SG-CQB". It can be used by every GIGN operator sans Montagne and NIGHTHAVEN attacker Grim. It is the only pump-action shotgun that can be fitted with a vertical foregrip, and weapon animations change correspondingly when the grip is used.

Saiga-12K

A heavily customized Saiga-12K, most closely resembling ones customized by the Hatcher Gun Company, appears as the "SASG-12" (which The Division followed suit with). It has a RIS foregrip with an aftermarket front sight and an AK-12 rear sight mounted on top, an aftermarket trigger-guard, Hogue pistol grip, and a CAA CBS AR-15 stock. It uses 8-round box magazines. The Saiga-12 is used by Spetsnaz defender Kapkan, CBRN Threat unit's Finka and certified mad scientist Fenrir.

The weapon is the most powerful semi-automatic shotgun available that uses buckshot, but is offset by having the highest recoil aswell.

Mossberg 590A1 Blackwater

The Mossberg 590A1 Blackwater is available in the game, issued to the SAS, Secret Service operator Warden, and Deimos. The M590A1 was also sometimes used by terrorists in the Terrorist Hunt mode, though they usually carried assault rifles. Although in-game, the M590A1 hold 7 rounds, it is modeled with a 9-round magazine-tube.

Remington 870 (G&P M870 RAS)

A short-barreled Remington 870 equipped with a Command Arms UPG16 modular pistol grip, 6-postion M4 stock, bolted-on extended top rail, and flip-up iron sights is available to the post-Operation New Blood reworked Defender Recruit Sentry, both the GSG-9 Defenders Jäger and Bandit, and the Irish Garda ERU Defender Thorn. It is closely modeled after the G&P M870 RAS, an airsoft Remington 870.

The weapon is the second most powerful shotgun in the game, although somewhat "balanced" by the fact that its efficiency diminishes greatly beyond point-blank range.

Benelli M3 Super 90 Shorty

The Benelli M3 Super 90 Shorty has been available in the game since the Operation Black Ice expansion was released, for JTF-2 defender Frost and later the fictional Inkaba Task Force's operator Melusi. It is referred to as the "Super 90," and operates exclusively in semi-automatic mode.

At release, the Super 90 infamously had extremely long effective range for a shotgun before receiving two nerfs to range and pellet spread, leading to the fan nickname of "Sniper 90".

M26 Modular Accessory Shotgun System

The JTF-2 operator Buck uses the M26 Modular Accessory Shotgun System as his gadget, equipped to whatever primary weapon (i.e. "C8-SFW" or "CAMRS") he is using. It is named the "Skeleton Key", an obvious allusion to the Knight's Armament Masterkey's name, and also a likely nod to how the fictional Skeleton Key can open any door, paired with the fact the M26 was designed to be a door-breaching (or wall-breaching as the design is applied in Siege) shotgun. It has a very large spread that limits its use in combat and at range, but is very destructive, able to create giant peek holes on walls with ease when combined with its spread. Like in previous games, the M26 in the game is semi-automatic, while the real one is a straight-pull bolt action.

Franchi SPAS-12

The Franchi SPAS-12 is used by Navy SEAL Operator Valkyrie and GIGR guest Operator Oryx. As with the Benelli M3, it operates only in semi-automatic mode. Despite being modeled with an 8-round magazine tube (holds 9 rounds in total), the SPAS only holds 7 (6+1) rounds in-game.

The last addition of the Operation Skull Rain update is the SPAS-12's successor, the Franchi SPAS-15, used exclusively by BOPE operator Caviera. It is depicted as semi-automatic only, and properly utilizes its bolt catch mechanism.

Benelli Supernova

The Benelli Supernova was added in the Operation Red Crow expansion, and is available to both SAT Operators, and the Peruvian Operator Amaru added in Y4S3. Its low damage and slow cycling speed takes a toll on its damage output, but offers excellent recoil control.

FABARM STF 12

Two variants of the FABARM STF 12 are introduced in Operation Velvet Shell, the Pistolgrip F.E. (without the muzzle brake) as the primary "ITA12L" and the Short Initial as the secondary "ITA12S". The ITA12S was the only secondary shotgun available in the game until the release of the "Super Shorty" in Operation Burnt Horizon of 2019. Both variants are available for both G.E.O. operators introduced in Operation Velvet Shell, while the secondary ITA12S is also available to Peruvian Operator Amaru introduced in Operation Ember Rise, post-Operation New Blood Attacker Recruit Sentry, JTF2 Operator Frost, and 35th Commando Battalion Operator Ram from the Operation Heavy Mettle expansion. The ITA12S is available to AFEAU operator Solis introduced in Operation Solar Raid as a primary option as well.

Crye Precision SIX12

The Crye Precision SIX12 is available for both SDU operators introduced in Operation Blood Orchid, and comes in two variants, the standard variant as "SIX12" for Attack operator Ying and the integrally suppressed as "SIX12 SD" for Defense operator Lesion. Danish Jaeger Corps Operator Nøkk, added in Y4S2, also uses the SIX12 SD.

Interestingly, the two variants are unique even beyond the suppressor, with the standard variant being based on a prototype model of the SIX12, and the SD being based on the production version. This can most easily be seen in the much thicker buttpad of the SD. Several other surface details also differentiate the two guns that could have, for all purposes, used the same model for everything rearward of the suppressor.

Fostech Origin-12

The Fostech Origin-12 is available in the game with the Operation Blood Orchid expansion. It is referred to as the "FO-12", and is used by the GROM defender Ela. The weapon currently has the highest RoF out of any semi-automatic shotgun in the game and can also be equipped with a long-barrel to increase its damage over distances.

"BOSG.12.2"

The "BOSG.12.2" (BOSG presumably standing for Break-Open Shotgun, compare with how "SASG" likely stands for Semi-Auto Shotgun) is a tactical over/under shotgun that is usable by the 707th SMB operators introduced in the Operation White Noise expansion. It shares many design elements with the Mossberg Maverick HS-12 and Stoeger Double Defense Over and Under shotguns. It fires slug shells, unlike the other shotguns in the game. These slugs are extremely powerful and accurate, even at longer ranges. Plus its ability to fire both barrels in quick succession allows it to devastate operators once hit. Although, as a trade-off, its 2-round capacity and long reload time heavily punishes missed shots, plus its ability to damage the environment is limited.

During public testing, the weapon was originally capable of penetrating the bulletproof windows of the executive jet in the "Presidential Plane" map, something only Glaz's SVU can do, but this ability was later removed in the official release.

AA-12

Added in Operation Para Bellum, the "ACS12" is a modified AA-12, and can be used by the two operators added in that expansion, Maestro and Alibi. It is also used by literal ronin Azami. Its standard iron sights are missing, the weapon instead being fitted with a G36C-like top rail system for mounting optics, a corresponding low-profile extended charging handle, and a handguard seemingly inspired by the Mk 14 Enhanced Battle Rifle's Kydex handguard, with rail segments on its sides and bottom. It uses 20 or 32-round drum magazines in-game, which incorrectly hold 30 rounds (plus an incorrect 1 in the chamber, Ubisoft either not realizing or caring that the AA-12 is open-bolt).

Of note is that the addition of the "ACS12" marks the appearance of Siege's first (and so far only) fully-automatic shotgun, which also made it the single most destructive weapon in terms of environmental destruction, able to eat through an entire wall in seconds. Balancing out its full-auto capability is its very big spread and the lowest damage of any shotgun in the game, but that's just another plus when you're busy bulldozing entire rooms because it allows more destruction per shot. During Operation Steel Wave however, the "ACS-12" was balanced to utilize slugs due to its low pick rate among the Italian operators, largely losing its destructive potential while making it more effective at longer ranges.

Incidentally, the name "ACS12" was first used for this weapon in a previous Ubisoft game, Splinter Cell: Blacklist. Presumably Ubisoft has its own dictionary for non-trademark-infringing weapon names for its allegedly interconnected video game universe spanning multiple franchises.

While the AA-12 is correctly animated as having a non-reciprocating bolt handle when firing, the empty reload animation incorrectly shows the bolt reciprocating forwards when the player character releases it after pulling it back.

Akdal Arms MKA 1919

A heavily customized Akdal Arms MKA 1919 semi-automatic shotgun is available with the Operation Wind Bastion Expansion. The customizations include the lower receiver being modified to fit a Bushmaster ACR stock and Magpul MOE pistol grip, a modified Chaos quad-rail hand guard, a shortened 13" barrel with appropriately modified gas-system, the front sight repinned to the barrel, an enlarged charging handle and bolt-release paddle, and custom 10-round magazines.

Simply dubbed "TCSG12" in-game (presumably standing for "Turkish Combat Shotgun"), the weapon is used by GIGR defender Kaid and Mexican FES defender Goyo. The shotgun only fires slugs, just like the "BOSG-12.2".

Remington 870 MCS

While referred to as a "Super Shorty", the secondary shotgun initially made available (a later update removed Mozzie's Super Shorty) to both Australian operators in Operation Burnt Horizon is actually a Remington 870 MCS, in the short-barreled "Masterkey" configuration, as evidenced by the MCS's distinctive forend (compared to the Super Shorty's folding foregrip).

An update made the 870 MCS Masterkey available as an alternate secondary in FBI operator Castle's loadout, and it is also an available secondary for the Defender Recruit Sentry, SDU Defender Lesion, MPS Defender Clash, and COT Attacker Brava.

Sniper Rifles

SVU Dragunov

The SVU Dragunov appears as the "OTs-03", and is used by the Spetsnaz operator Glaz. The weapon has the best surface-penetrating capabilities of any weapon, being capable of piercing a wide variety of surfaces with a minimal loss of damage, and, prior to Operation White Noise and its addition of the "BOSG. 12.2", being the only weapon capable of shooting through airplane windows (specifically the reinforced airplane windows on the map "Presidential Plane", which is also the only place where they appear); after the aforementioned weapon's mechanics were changed, it once again became the only weapon capable of such a feat.

Glaz's unique gadget is the magnifier on the rifle, which can be flipped into or out of the main sight plane; this does not actually require an optical sight to use, with the front iron sight serving as the reticule instead in the absence of other optics. The sight is originally a rather odd red-tinted (or completely clear, as shown in the Spetsnaz trailer) magnifier called the "HDS Flip Sight", which had no effect other than a bit of zoom. In the Velvet Shell Mid-Season Reinforcements, the magnifier lost its red tint and gained a thermal effect, highlighting enemies by their heat signature; this effect, strangely, only applies to a smaller central blue-tinted circle in the magnifier, rather than the entire thing.

A rather neat detail is that after the thermal sight update, the sight model had an extra clip-on thermal imager added to it.

"CSRX 300"

NIGHTHAVEN operator Kali uses a fictional custom-built rifle known as the "CSRX 300" as her sole primary weapon. The rifle appears to take design cues from the Blaser R93 and the Accuracy International Arctic Warfare series of rifles, with an underbarrel launcher resembling the FN EGLM. As the name implies, the rifle is chambered in .300 Winchester Magnum. The rifle has a custom scope that allows the player to switch between x4 and x12 zoom. In-game, players shot by the rifle are instantly downed, though the sniper rounds leave tell-tale vapor trails. The underbarrel launcher fires an explosive drilling device that can destroy barricades (including Castle's barricades) and floor hatches, and creates small holes in breachable walls. When penetrating walls, the explosive destroys any placed gadgets within the blast radius.

Launchers are almost always Operator gadgets. Other launchers of note include Capitão's crossbow, Hibana's X-KAIROS, Zofia's KS79 LIFELINE, Nomad's Airjab Launcher, Kali's LV Lance, Grim's Kawan launcher and the generic GONNE-6 "Hand Cannon" gadget (actually a single-shot rifle), not listed here for one reason or another.

Heckler & Koch M320

The Heckler & Koch M320, indexed as "M120 CREM," is used by the FBI SWAT operative "Ash". It appears stand-alone in the game with a longer barrel and an under-barrel rail with an attached vertical grip instead of the the built-in folding vertical grip. In-game it fires specialized (and, given the reload animation, seemingly caseless) breaching rounds that drill into destructible surfaces, then explode after a delay in order to ensure maximum penetration. The shell does not explode if it does not hit a breachable surface.

To the relief of some and the disappointment of others, the game's list of "breachable surfaces" does not include enemies, although getting directly struck with the shell deals a moderate amount of damage. While the breaching round itself also has a small blast radius and is not reliable against human targets, getting caught in the explosion of an armed round deals a large amount of damage.

Kulakov Revolver Grenade Launcher

The October 2020 Tachanka rework adds a Kulakov Revolver Grenade Launcher to his arsenal as his new gadget, known as the "Shumikha" in-universe. For whatever reason, the Shumikha fires incendiary grenades instead of high-explosives, and its operation is utterly bizarre: the Mosin's receiver is treated as semi-automatic and the bolt blows back like a gas-operated weapon, despite the real deal (still) being bolt-action, and the magazine of the launcher component itself is not animated, with Tachanka simply cramming in more grenades through the static loading gate when reloading the weapon without indexing the drum at all. The pistol grip is also absent; the stock also seems to be a non-standard partial C-grip style.

As an unintentional bit of irony, the in-game write-up claims that replacing Tachanka's machinegun stand with the Shumikha will lighten his gear load, while one of the main reasons leading up to the Kulakov being rejected in the first place was how heavy and unwieldy it is to use as a standard-issue weapon. To put it into perspective, an unloaded Kulakov weighs significantly more than a fully-loaded DP-28 (15kg vs. 11.5kg), and was designed to be fired with its bipod deployed.

Grenades & Explosives

Most equipment in this category are non-exclusive "generic" gadgets available to multiple Operators (alongside things like Barbed Wire and Deployable Shields), though they are still limited to one team.

C4

Bundles of C4 charges, somewhat strangely referred to as "Nitro Cells", are available for certain defenders. Unlike other explosives; the C4 sticks to surfaces and is manually detonated with a cellphone.

The weapon is currently the most powerful explosive available, capable of outright killing anyone caught in its 5m blast radius; however, as a heavy explosive, its throwing distance is considerably shorter than that of grenades. It also emits a faint beeping sound once deployed, which can potentially alert attackers to its presence. Much like a real C4, the charge will only explode if its triggered by the user. Attacking it will simply destroy it, and if the user dies before the charge is triggered, the C4 is essentially rendered inert.

M18 Smoke Grenade

The M18 smoke grenade is available to attacking operators.

M67 Hand Grenade

The M67 hand grenade is given to some attacking operators.

The weapon explodes after 4 seconds and deals high damage, although since the grenade is primarily focused on scattering shrapnel than an explosion, it does less environmental damage than the impact grenade. The grenade can be cooked to reduce the chances of an enemy escaping the blast once thrown; however, cooking it for longer than 4 seconds will cause it to detonate, killing the wielder and anyone else unlucky enough to be near them.

M84 Stun Grenade

The M84 stun grenade is another non-lethal grenade for attackers.

M18A1 Claymore Mine

The M18A1 Claymore was added in the September 13, 2016 patch 4.2 for attacking operators. The weapon is very powerful, capable of incapacitating or outright killing anything infront of it once it goes off.

Unlike traditional claymores, the mine is triggered with three laser beams arranged in a triangular pattern, that extend upto three meters each. If a defender touches any of the lasers: the mine will explode in a 180-degree radius, with a lethal range of upto 5 meters. Although as a balancing measure, both teams can see the claymore's lasers.

T13 Beano grenade

The Impact Grenade was added on September 13, 2016, in patch 4.2. It is a modernized depiction of the WWII-era T13 Beano impact grenade. It is exclusive to defenders and deals limited damage in a small radius of 2.5m (in fact you'd actually have to throw it directly at someone to get any kind of decent damage). However, its small explosion radius and damage means its relatively safe to throw around to create large openings in destructible surfaces for other operators to pass through, in comparison to other explosives.

A modified version of the T13 Beano was added as the "Impact EMP Grenade" secondary gadget.
