Ghost in the Shell 2: Innocence
The following weapons were used in the anime film Ghost in the Shell 2: Innocence:
Futuristic IMI Jericho 941
Batou carries a futuristic IMI Jericho 941 derivative with a railed frame, a low-profile rear sight, and what seems to be a slightly longer squared-off slide, likely meant to be the "Jericho 942" from the first film.
Smith & Wesson 6906
Batou uses a Smith & Wesson 6906 equipped with a ring hammer as his backup gun in the convenience store shooting when he thinks he is under attack.
Batou takes a Stechkin APS fitted with a stock from Yakuza officer Wakabayashi after shooting down the two grenades he throws at him and Togusa.
Several Yakuza thugs uses Colt M1911s.
AMC Auto Mag
One of the first Yakuza members to draw their gun has a AMC Auto Mag.
A Yakuza thug draws a SIG-Sauer P228.
One Yakuza thug draws a very rare and obscure Manurhin MR-96 revolver. Interestingly it is depicted with a non-existent stainless steel finish when Manurhin MR-96s were only ever made with a deep blued finish.
Togusa continues to carry his Mateba M2007, a fictional version of the Mateba 2006M, from the previous Ghost in the Shell film.
Ruger Super Blackhawk
A Yakuza thug draws a custom-ported Ruger Super Blackhawk on Batou.
Two of the Yakuza thugs use Ingram MAC-10s during Batou's attack.
Anti-Firearms Squad officers are in possession of Steyr TMPs stocked in the opening.
FN P90/Izhmash PP-19 Hybrid
Assault Rifles & Carbines
Batou's Assault Rifle
During the film's finale, Batou uses a fictional assault rifle. This weapon is something of a conglomeration of various designs; The upper receiver, charging handle, and magazine are from the SIG SG 510-4. The lower receiver, folding stock, and receiver hinging system are from a FN FAL Paratrooper. While the barrel, flash hider, gas tube, and bipod draw from the Galil Sniper Rifle, the bipod is attached in front of the receiver like a Galatz rifle. The rifle also has an IMI Galil ARM handguard, a heat shield over the barrel, and the size of the magazines suggests that is is chambered for 7.62x51mm NATO (both the dialogue and the director's commentary describe it as being a ".30 cal."). The overall design also bears a resemblance to the Stoner 63 machine gun.
Bushmaster Arm Pistol
One of the Yakuza thugs is seen using a Bushmaster Arm Pistol.
One Yakuza fires at Batou with a FAMAS G2 using a 30-round STANAG magazine.
Steyr AUG A1
One Yakuza thug fires a Steyr AUG A1 with a birdcage flash hider.
Futuristic Norinco SAS-12
In the opening sequence of the film, Batou uses a short barreled semi-automatic shotgun with a pistol grip and heat shield to stop a homicidal and "suicidal" love doll. He also has the shotgun with him in the final scene. It seems to be solely based on the Norinco SAS-12 but with a more beefed up receiver, a left side charging handle, and both a paddle and AR-15 style magazine release.
Mossberg 590 Compact Cruiser
One of the Yakuza thugs uses a Mossberg 590 Compact Cruiser.
Batou, to the dismay of Togusa, uses a FN Minimi to mow down a group of Yakuza thugs. Also worth noting is that the weapon has an unusual blue muzzle flash, as do most other weapons in that scene.
Integral Cyborg ARMGUN
In the final fight with the dolls, Batou uses a double barrel gun hidden in his forearm.
A group of five Phalanx CIWS turrets can be seen firing at a mansion in Togusa's digital nightmare.
Yakuza Officer Wakabayashi throws two grenades that resemble M67 hand grenade's down a flight of stairs to Togusa and Batou.
