List of gun abbreviations
- 22H: .22 Hornet
A somewhat antiquated notation system for cartridges, commonly known as "blackpowder notation" due to its use with black powder cartridges; the first number represents the caliber (in inches), while the second is the standard powder loading (in grains). For example, the .45-70 Government cartridge propels a .45-inch bullet (.458-inch, to be exact) with 70 grains of black powder. Occasionally, there will be a third number after this denoting bullet weight in grains (e.g. .45-70-405), though this is less common, as different bullet weights are more a matter of the loading of the cartridge than the chambering of the firearm.
There are several exceptions to this system, such as:
- .56-56 Spencer, which denotes the diameter of the case at the base (just above the rim), and the diameter of the case at the mouth; later variations of the cartridge (.56-52, .56-50, .56-46, etc.) had tapered cases and smaller bullets, whereas the original .56-56 round was straight-walled.
- .577-450 Martini-Henry, which denotes the caliber of the parent case (the .577 Snider), and the diameter of the actual bullet (.450, or more precisely, .455).
- .30-30 Winchester, which is named for its caliber (.30 in, though more accurately .308) and a hypothetical black powder loading of 30 grains, despite the round never actually being commercially loaded with black powder.
- .30-06 Springfield, which denotes caliber (.30, though, again, more accurately .308) and year of adoption (1906); the earlier, 1903-issued version of the cartridge is likewise designated .30-03.
- .250-3000 Savage, denoting caliber (.25, or more precisely .257) and muzzle velocity (3,000 feet per second, at least when loaded with 87-grain bullets).
- .38-200, a British-issued loading of the .38 S&W round, which is named for its caliber (.38, though in practice closer to .361) and its bullet weight (200 grains).
- .22-250 Remington, named for its actual caliber (.22, or .224 if an extra significant figure is added) and the caliber of its parent case (the aforementioned .250-3000 Savage).
- .25-06 Remington, which denotes caliber (.25, or again, .257) and the date of adoption of the round upon which it was based (.30-06 Springfield).
- 7-08 Remington, which is named for its caliber in millimeters (7mm) and the last two digits of its parent case's diameter, in inches (.308 Winchester).
- .25-45 Sharps, a contemporary hunting round meant for AR-15-patterned rifles, named for its caliber (.25, though again, really more like .257) and its case length (45mm, because using one system of measure at a time is apparently not good enough).
- ACP: Automatic Colt Pistol
- AE: Action Express
- AMP: Auto Magnum Pistol

- BAT: Battalion, Anti-Tank
Name of a series of British 120mm recoilless rifles (L2 BAT, L4 MoBAT, L6 WOMBAT and L7 CONBAT). In ammunition terms, .50 BAT is the term applied to the 12.7x77mm spotting round used by the Remington M8C on the M40 Recoilless Rifle. It takes this unofficial name from the British version of the M8C, the L40A1 spotting rifle, which was first mounted on the WOMBAT.
- BGM: This is a US Army code for missiles rather than a direct acronym: it designates the missile as a multiple launch environment (B) ground-attack (G) guided missile (M). The B prefix indicates the missile can be used from a variety of launching platforms with little or no modification.
- BMG: Browning Machine Gun, refers to the .50 caliber cartridge designed for the Browning M2, also known as the 12.7x99mm NATO.
- Cal: Caliber
Depending on the type of weapon, this can either refer to the bore diameter of the barrel (usually when it is being expressed in inches), or to the ratio of the interior diameter of the barrel to its length on large guns. For an example of the latter, the "16 inch 50 cal" guns of an Iowa-Class battleship are 16 inch bore, with a barrel 50 bore diameters (800in or 66ft 8in) long.
- CheyTac: Cheyenne Tactical
- Chicom: Chinese Communist
Informally used to refer to weapons or ammunition manufactured in China after the establishment of the PRC in 1949.
- CL: Caseless
Round type where a hardened propellant block removes the need for a conventional case. Usually does not include rounds with combustible cases which are destroyed during firing. Russian "caseless" VOG and GRD grenades are a borderline example since the lower part of the projectile is a vented "case" which is fired along with it, they are functionally more similar to mortar rounds than true caseless ammunition.
- CS: Corson Stoughton.
Surnames of the two scientists who discovered the tear gas 2-chlorobenzalmalononitrile in 1928.
- CT: Cased Telescoped (also CTA: Cased Telescoped Ammunition)
Unorthodox cartridge type where the bullet is seated deep within the casing and partially or completely enveloped by the propellant, allowing a shorter overall cartridge length for the same size of bullet.
- EFP: Exposively Formed Penetrator
Most common in missile warheads, this is a special type of shaped charge warhead where the explosive force is used to form a solid dart aimed in a particular direction from a sheet of a suitable metal such as copper or tantalum.
- EXACTO: EXtreme ACcuracy Tasked Ordnance
DARPA's .50 caliber guided bullet program that began in 2008, and a backronym if ever there was one.
- FMJ: Full Metal Jacket
- Ga: Gauge. A shotgun's gauge is the number of spheres the diameter of the barrel which can be made from one pound of lead. For example, 12 balls can be made to the diameter of a 12-gauge shotgun's barrel, and 20 for a 20-gauge. This is why larger numbers equal smaller calibers. Non-numeric notation (B 1/2, A and AA) is used for some gauges less than 1.5, though these only apply to antique punt guns. The exceptions to this rule are .410 gauge, which is the actual barrel caliber in inches (more unambiguously called .410 bore), and the Russian 23mm caliber used by the KS-23.
- GAP: Glock Automatic Pistol
- Gr: Grain
Imperial measurement in the troy weight series, used to measure propellant and bullet weights. It is equivalent to 0.00228571 ounces or 64.79891 milligrams and exactly 1/5760 of the Troy Pound used to measure gold.
- HC: Hexachloroethane
A filler used in smoke grenades, usually as hexachloroethane-zinc.
- HE: High Explosive
- HEAA: High Explosive Anti-Armor
- HEAB: High Explosive Air Burst
- HEAP: High Explosive Anti-Personnel
- HEAT: High Explosive Anti-Tank
Used for hollow charge / shaped charge weapons. The term HEAT leads to a misconception that these weapons' primary damage mechanism is thermal: they are actually kinetic weapons, with the jet of metal which is formed behaving like a solid.
- HEDP: High Explosive Dual-Purpose
Fragmenting HE round with an added hollow charge to increase effectiveness against armor.
- HE-Frag: High Explosive-Fragmentation
- HE-I: High Explosive-Incendiary
- HEI-T: High Explosive-Incendiary, Tracer
- HEIT-SD: High Explosive-Incendiary Tracer, Self-Destruct
- HEP: High Explosive, Plastic (known in the UK as HESH: High Explosive Squash Head)
Ammunition type used in some recoilless rifles and tank and combat engineering vehicle guns, primarily used for demolitions. The projectile is formed from malleable explosives that flatten against the target before detonating, with the idea of anti-tank use being to induce spallation (breaking off of the interior of armor due to shockwaves, with the idea being that the armor fragments will damage internal systems and / or kill crewmen) rather than penetration. Modern composite tank armor is a poor conductor of shockwaves, hence its obsolescence in this role.
- IMI: Israel Military Industries
- JHP: Jacketed Hollow Point
- JSP: Jacketed Soft Point
- LC: Long Colt
- LR: Long Rifle
- L'Spur: Leuchtspur
Transl: Tracer (lit: "light trail")

- Mag: Magazine
- Mag or Mag.: Magnum
- mm: millimeter
- MOA: Minute Of Angle
Angular measurement referred to as a minute of arc by other fields, representing one sixtieth of a degree (ie, there are 21,600 MOA in a circle). It is used to describe accuracy of both ammunition and weapons in terms of grouping size when fired from a machine rest, and used to adjust scopes with knobs measured in MOA-fraction "clicks." 1 MOA roughly corresponds to a 1-inch spread (1.047 inch to be exact) per hundred yards of distance: so, for example, a 0.5 MOA weapon will shoot a 1.5 inch group at 300 yards.
- Mil / mrad - Milliradian / Milliradian
SI equivalent of the minute of angle: there are 2000π mils (~6,283.2) in a circle, and 1/10 mil is equivalent to 1cm at 100m: 1 mil is equivalent to 3.4377 MOA. Artillery sights and angular map measurements use different definitions to make for easier work without involving π: a NATO mil is 1/6400 of a circle (ie there are 17.7 recurring per degree), the Warsaw Pact used 1/6000 (16.6 recurring per degree), and Sweden and Finland used to use 1/6300 (called streck mils, exactly 17.5 per degree).
- MPTs: Malokaliberniy Pistoletnyy Tsentralnogo vosplameneniya
Transl.: Small caliber centerfire pistol cartridge
- NATO: North Atlantic Treaty Organization
Note: With regard to firearms, this is used in the context of NATO-standardised ammunition, such as 7.62x51mm.

- A, as in M16A4 or M4A1: Advancement or Alteration
Denotes a subvariant of a weapon which is not held to be a large enough change to warrant a new Model number being assigned. US Navy, Marine Corps and SOCOM equivalent is Mod.
- In German weapons (e.g. MP5A3), it instead stands for Ausführung (Version, in German: this is also the "Ausf." frequently seen in WW2 German tank names).
- AA: Anti Aircraft

- AMD-65: Automata Módosított Deszant - 1965
Transl.: Automatic Modified Landing Assault weapon - 1965
- AMT: Arcadia Machine and Tool
- AN: Army and Navy
Used in the format AN/M(number) generally to indicate weapons used by or on aircraft of both the Army Air Forces and United States Navy, including signalling devices which were also used by ground troops (eg the AN/M8 HC smoke grenade and AN/M14 incendiary grenade which could both be used as sea-markers, or the AN/M8 Pyrotechnic Pistol). Though it carried on being used for a while after the establishment of the US Air Force, it is no longer commonly used for weapons, having been replaced by the GAU- prefix for aircraft cannons.
AN's primary modern use is as part of the all-service Joint Electronics Type Designation System which was first adopted in 1943, originally just for airborne, radio and radar equipment. It is now used for all electronic equipment regardless of which service uses it: for example, the AN/APQ-164 is a phased array radar used only by the Air Force's B-1B Lancer. As a result, AN designations will turn up on devices like electronic weapon sights and laser modules.
- AN-94: Avtomat Nikonova - 94
Transl.: Automatic device of Nikonov - 1994
- API: Advanced Primer Ignition
Open-bolt blowback operating method used on most open-bolt submachine guns and pioneered on heavy weapons by the Becker machine gun. The round's primer is ignited during the forward stroke of the bolt before the round is fully chambered, forcing it to use part of the energy that would normally become recoil to arrest the forward motion of the bolt. This can be used to reduce the weight of the bolt group in order to make a lighter weapon with the same felt recoil, or simply to reduce felt recoil.
- APS: Avtomaticheskiy Pistolet Stetchkina
Transl.: Automatic Stechkin Pistol
- APS: Avtomat Podvodnyy Spetsialnyy
Transl.: Special Underwater Automatic Rifle
- AR: Assault Rifle
- AR: Automatic Rifle
- AR: ARmaLite

- BDA: Browning Double Action
- BDM: Browning Double Mode
- BDM: Bunker Defeat Munition
- BFA: Blank Firing Adaptor/Attachment

DA includes DAO (see below), but also includes designs which allow the hammer or striker to be cocked manually for a lighter trigger pull, and DA / SA designs which by default use the operation of the weapon to cock it and fire single-action, but can fire in double-action mode if the hammer is not cocked.
- DAK: Double Action Kellerman
- DAO: Double Action Only
The weapon's trigger performs the actions of cocking and releasing the hammer / striker. The weapon is only cocked during the action of operating the trigger.
- DEFA: Direction des Études et Fabrications d'Armement)
Transl.: Directorate of Armament Studies and Fabrications
- Demil: Demilitarize
Official term for a country-specific procedure that usually removes a firearm's legal status as a firearm by removing key parts, welding or plugging parts of the mechanism and cutting components such that it could not reasonably be used to fire live ammunition. Demilled firearms often have external signs of being deactivated such as diagonal marks where the receiver has been cut at an angle and then welded back together.
- DEWAT (variously capitalized): DEactivated WAr Trophy
DEWAT (not necessarily capitalized) refers to a specific class of deactivated NFA weapons, which are still regarded as firearms and must be registered despite being deactivated. Usually they have been deactivated to a lower standard than being demilled and so are sought after because they can often be rendered serviceable again by a sufficiently qualified gunsmith: because they are already registered as whatever they are, this only requires the payment of the NFA "manufacturing / making" fee and updating some paperwork. In spite of the past tense being "dewatted," it has nothing to do with electricity.
- DMR: Designated Marksman Rifle
- DMS: Dual Mount System
Tripod-mounted twin FIM-92 Stinger launcher with built-in radio and datalink.
- DShK: Degtyaryova-Shpagina Krupnokaliberny
- E: Experimental
When part of a weapon's name, E denotes a modification which is under testing or low-rate production, and hence does not yet rate a change to the A (alteration / advancement) number assigned to the weapon. For example, a weapon called M99A7E2 would be the second trial alteration of the A7 modification of the Model 99. This weapon, assuming it is a rifle, would be fully called "Rifle, Model 99, Alteration 7, Experimental 2." If accepted into production, it would become the M99A8.
- EAA: European American Armory
- EBR: Enhanced Battle Rifle
- ECOS-N: Enhanced Combat Optical Sight - Navy

- ELCAN: Ernst Leitz Canada
Former Canadian subsidiary of German camera company Ernst Leitz GmbH (now Leica Camera AG), sold to Hughes and now part of Raytheon. In firearms, refers to the Specter series of telescopic sights produced by this company, which includes the Canadian C79 optic and the US Army's M145 Machine Gun Optic.
- EMag: Export Magazine
- EMR: Enhanced Marksman Rifle
- ESR: Enhanced Sniper Rifle
- ETC: Electro-Thermal-Chemical, an experimental form of ignition system only likely to be encountered in science fiction smallarms, since all current experimental ETC guns are tank guns or artillery systems. The system uses an electrical charge to turn the primer into plasma, potentially allowing for highly controlled and complete combustion of the propellant and for more stable propellants to be used which would not work with conventional explosive primers.
- Effective Range: While not an abbreviation as such, this can be a source of confusion since it means different things for different weapons.
- Absolute maximum effective range is the range after which the round's energy drops to the point it could no longer be considered lethal. It is often used in press materials making slightly absurd range claims; for example, this is the "effective range" used in claims that the P90 is effective against unarmoured personnel at 400 metres. It should be noted that this range figure does not require that the shooter actually be able to hit their target reliably.
- Maximum effective range on a point target is typically used for smallarms, and is judged as the distance at which the weapon can hit a human torso-sized target 50% of the time when secured in a machine rest. It does not, however, require that the round retains lethal energy at that time, and if it does not then the absolute maximum effective range will be quoted instead.
- Maximum effective range on an area target is the distance at which the weapon lands 50% of shots inside an area of defined radius, and is typically used for machine guns, hence their enormous effective range figures even when compared to a rifle firing the same round. It does not, however, require that the round retains lethal energy at that time, and if it does not then the absolute maximum effective range will be quoted instead.
- Sniper rifle effective range is the distance at which an expert marksman can be expected to achieve a guaranteed strike on a human target.
These are differentiated from the weapon's Absolute maximum range, which is usually only quoted as the range for heavy artillery firing explosive rounds and is the maximum possible range the weapon can fire a round regardless of whether it can hit or destroy a target. As an example of the difference, the effective range of a Beretta M9 (versus a point target) is 50 metres, while the maximum range of a Beretta M9 (aiming it up in the air like a mortar) is 1,800 metres.

Sometimes rendered instead as Gun Aircraft Unit, but this is incorrect: it is the "/A" at the end of Air Force weapon designations that denotes an aircraft-mounted weapon. GAU is a two-part code, denoting an automatic gun (GA) which is a complete functional unit (U) rather than a parts kit. GAU with a /A was originally used to denote Air Force personal weapons as well (eg GAU-5/A) but this has been changed to referring to these weapons as "GUU" ("guns, miscellaneous personal equipment") with a /P ("personal") suffix.
- GIAT 30: Groupement des Industries de l'Armée de Terre 30 millimeter

A GPMG is a machine gun capable of being employed in both the light machine gun role (firing in short bursts, typically using a bipod) and medium machine gun role (firing for prolonged periods on a sustained fire mount such as a tripod). Modern GPMGs are effectively medium machine guns, almost always firing a full-sized rifle round, but are more portable and flexible than weapons classified specifically as medium.
- GSh-18: Gryazev Shipunov-18
Names of the designers.

Feature of some modern guided weapons, mostly anti-tank missiles. The weapon is launched "blind" and then acquires a lock-on after being fired, allowing for non-line-of-sight fire and use of third-party target designators.
- LOSBR: Line Of Sight Beam Riding
Laser or radar guidance system for missiles, usually SACLOS though ACLOS is possible with a radar beam. Unlike semi-active laser homing (SALH) or semi-active radar homing (SARH) where the missile seeks the reflected energy from a beam pointed at the target using a sensor in its nose, a LOSBR missile attempts to fly along the beam itself, detecting the beam using a sensor in its tail.

- LWRC: Land Warfare Resources Corporation
- M: Model
In US use, used to be followed by the year of adoption (eg Springfield M1903) but around WW2 it was decided that it should instead denote the weapon's position in a series, hence the large number of M1s that appeared at that time. Later it was discovered this was extremely confusing (imagine calling in support from "the M1s" during WW2) and so designations often skip numbers used by similar things, for example WW2 light tanks jumping from M3 to M5 to avoid confusion with the M4 Sherman.

Transl.: Light Machine gun, Degtyaryov's
- RoF: Rate of Fire. There are typically two "rate of fire" figures for a given weapon:
- Cyclic rate of fire is most commonly quoted, though is only normally used for fully automatic weapons. The figure is based on how quickly the weapon's action completes a single cycle of function. It is the absolute upper limit for how quickly the weapon can discharge ammunition, and does not include reloads, barrel changes, possibility of jams, etc. While a cyclic rate of fire could be calculated for any semi-automatic weapon (as the mechanism still cycles at a specific speed), it is seldom quoted as it is very rarely a limiting factor in the weapon's performance.
- Practical rate of fire is seldom quoted, as it involves operator experience and therefore will vary from person to person; if quoted, it is typically the minimum fire rate an operator is required to achieve in order to pass a military training standard for that weapon. As a result, there may be multiple practical rates for aimed fire at different ranges: for example, often-quoted practical RoF figures for aimed semi-automatic fire from an M16 are 45 rpm at 100 meters and 15 rpm at 300 meters. It includes reloading and barrel changes where applicable, but typically not including jams or malfunctions. Obviously, it is the only figure that can be quoted for manually-operated arms that do not have a cycle of function.

- RVG: Rail Vertical Grip
- RWS: Remote Weapon Station or Remote Weapon System
- S&W: Smith & Wesson
- SA80: Small Arms for the 1980s
- SA: Semi-Automatic
Semi-automatic weapons partially automate the process of operating the weapon using energy created by the round being fired; typically, in such a design it will be necessary to release the weapon's trigger to reset the sear and allow the weapon to fire again. Double-action revolvers are not semi-automatic weapons, since all the energy used to advance the cylinder comes from the user pulling the trigger; they are manually operated.
- SA: Single Action
Single action weapons only perform the single action of releasing the striker or hammer when the trigger is pulled; if the weapon is not cocked in some other fashion (the user racking the slide or manually cocking the hammer, or the slide in a semi-auto SA pistol reciprocating and pushing the hammer back) then pulling the trigger will do nothing at all. Sometimes written as SAO (Single Action Only), though this is a little redundant unless trying to avoid confusion when talking about a single-action semi-automatic.
- SA: Surface to Air
NATO prefix used for Soviet / Russian SAMs and MANPADS.
- SAA: Single Action Army
- SABR: Sniper Assaulter Battle Rifle (LWRC SRT variant)
- SABR: Selectable Assault Battle Rifle (Alternate name for the OICW)
- SACLOS: Semi Active Command Line Of Sight.
A method of guiding munitions where the user gives the projectile an aim point and the projectile's flight path is corrected to intersect with that point, usually through either the weapon's sight tracking a beacon on the projectile and transmitting instructions to it, or with the projectile containing a passive seeker system and guiding itself to a target indicated by an active designator. What unifies these is that one part of the system is a passive detector, which looks for an active signal created by the other: hence the system is semi active. This includes SALH (Semi Active Laser Homing) and SARH (Semi Active Radar Homing) where the designator is respectively a laser and an active radar reflected off the target.

Further note: STANAG 4179, the draft standard, was a suggestion in 1980 to standardize the M16 20- and 30-round magazines for all NATO rifles, but was never passed, largely because of French and German interest in proprietary magazines for the FAMAS and G11. In modern use "STANAG" is used to refer to magazines designed for the magazine well of the 5.56x45mm AR15 pattern lower.

This is for all Kalashnikov/similar guns related abbreviations. It should be noted that "avtomat" in Russian really only implies an automated machine of some kind; it is also a term applied to other devices such as slot machines. "AK" therefore in absolute terms means something along the lines of "Automatic device of Kalashnikov," but it is usually translated as "automatic gun" or "automatic rifle" due to context. It does not contain the Russian word for rifle, which is vintovka, or gun, which is ruzh'ya.
(This is much the same as the way "revolver" in English only means "thing that revolves" and is judged to refer to a gun with a revolving cylinder due to context.)

This section is for all Chinese 'Q' guns.
