In December 2025, months after the end of the events of Sword Art Online (Season 1), and Kazuto Kirigaya (Username: Kirito) is living peacefully back in the real world. However, he is recruited by Seijirou Kikuoka of the Ministry of Internal Affairs' Virtual Division to investigate in a series of killings in the Virtual Reality MMORPG game Gun Gale Online. A player calling himself "Death Gun" is suspected of causing the deaths of two GGO players via shooting their avatars in the game, somehow coincidentally causing their real bodies to suffer an acute heart attack.
Gun Gale Online is a sci-fi, gun-based VRMMORPG set on a post-apocalyptic Earth, featuring both real firearms as well as sci-fi blaster-style weapons called optical guns which fire light-based ammo; the former are intended for Player vs. Player combat, while the latter are generally for hunting NPC monsters. The main even in the story is a PvP battle royale style tournament called the Bullet of Bullets.
Sword Art Online II has multiple story arcs and settings within the season, featuring the Phantom Bullet, Calibur, and Mother's Rosario story arcs, just as the first season featured the Aincrad and Fairy Dance story arcs, and Extra Edition bonus episode. As Phantom Bullet is the only arc to feature firearms, it's the only arc to be featured on this page. Also, as the story is set in a video game, all of the guns in the show appear in that context, with the exception two; one of those two is an airsoft replica.
Warning: Some descriptions and images are potential spoilers for the series, read at your own risk.
The following weapons were used in the anime series Sword Art Online II:
The player calling himself "Death Gun" uses a Norinco Type 54 "Black Star" to supposedly murder players in Gun Gale Online. In the real world, a Type 54 was also used by a bank robber who was disarmed and killed with his own gun by Shino Asada (Username: Sinon) five years before the main story.
FN Five-seveN
After purchasing his Kagemitsu G4 photon sword, Kirito acquires an FN Five-seveN as his sidearm, per Sinon's recommendation. Sinon's HUD symbol for her sidearm, which is a Glock 18C, is occasionally misrepresented as a Five-seveN.
Glock 18C
Sinon uses a Glock 18C fitted with a 33-round magazine as her secondary weapon; in the original novels it was instead a Heckler & Koch MP7. Despite being in Sinon's holster for most of the story, it's easily the least-used weapon belonging to a main character.
Colt M1911A1
A sign for the Untouchable! mini-game in Gun Gale Online has an M1911A1 on it. In the real world, Endou, a school bully, later tries to use an airsoft M1911A1 borrowed from her brother to extort money from Shino.
Beretta 92FS
A player is seen firing a Beretta 92FS at the weapon market's firing range.
Unknown Pistol
Ginrou is seen dual-wielding a pair of unknown pistols in the Gun Gale Online introductory sequence.
Revolvers
Colt Python
A Colt Python was the first weapon used by Sinon in GGO.
Smith & Wesson Model 3
The mascot for the Untouchable! mini-game wields a Smith & Wesson Model 3 Schofield as his weapon. The mini-game requires the player to run up a narrow passage dodging the mascot's fire and successfully reach him. As a side note, the mascot speaks very good English, mostly consisting of taunts.
Colt 1873
A player competing in the Bullet of Bullets preliminaries is seen with a pair of Colt 1873s, better known as the Single Action Army. Also, during Sinon's explanation of the BoB tournament, players are seen in a Western face-off drawing Single Action Armys.
Submachine Guns
IMI Uzi
Jin, a member of Dyne's squad, wields an Uzi as his main weapon.
Heckler & Koch MP5A2
A player participating in the Bullet of Bullets tournament is seen using a H&K MP5A2, while another in the BoB waiting room is seen with an MP5 as well.
Heckler & Koch MP5SD3
A number of players are seen with MP5SDs with collapsible stocks in the BoB waiting room.
Heckler & Koch MP5K
A player with a H&K MP5K can be seen the first moment Kirito enters Gun Gale Online.
Heckler & Koch UMP40
Ginrou, a member of Dyne's squad, uses a H&K UMP40 fitted with a foregrip as his main weapon, denoted by its straight magazine and 30-round capacity.
Heckler & Koch MP7A1
A player in a chatroom has an avatar with a H&K MP7A1 on it.
MAC M-10
A player in the BoB tournament is seen using a MAC M-10 as his main weapon. One of the players that attempts to ambush Yamikaze during Sinon's explanation of his skill level was armed with an M-10 with the stock removed.
CZ Vz. 61 Škorpion
A player is armed with a Vz. 61 Škorpion in the GGO introduction sequence, while BoB participant Keith uses one during the tournament.
Calico M900
A Calico M900 in the long barreled, semi automatic carbine configuration without the M951 style foregrip is wielded by Yamikaze, previously the second-highest rated, and now highest-rated player in the Japanese GGO server. Sinon refers the Calico as an "ultra-lightweight machinegun, the Calico M900A". Despite M900A not being an official designation, given that the gun is a full-auto conversion of the civilian M900 model, it's the most appropriate designation given the rest of the Calico family.
Unknown SMG
A player participating in the Bullet of Bullets preliminary matches is seen with an SMG of some sort slung over his shoulder, likely WWII-era or earlier.
Assault Rifles
FAMAS G2
Player Usujio Tarako used a FAMAS G2 as his main weapon.
AK-74
A number of players watching the BoB tournament are seen with AK-74s.
FN SCAR
A BoB player killed by "Death Gun" was using a SCAR rifle, caliber unknown due to the angle. These players were killed by "Death Gun"'s L115A3, not the Type 54 that supposedly murders people in the real world; they're simply "dead" in a traditional video game sense.
Howa Type 89
Although Kyouji Shinkawa is never actually seen with his own main weapon in the show itself, he is seen with a Howa Type 89 on the bluray box cover art. In the novels, Kirito describes him as carrying a "somewhat large machine gun" slung over his shoulder; given Kirito's (lack of) expertise with firearms, this is an appropriate description for a full-size assault rifle like the Type 89.
Steyr AUG A1
A player is seen firing a Steyr AUG A1 at the gun market's firing range. The AUG will appear again in Sword Art Online, once the inevitable Season 3 (or more likely Season 4) is animated.
Colt M4A1
An M4A1 is used by Arashi, a member of Dyne's squad, as his main weapon; in the novels he is referred to as "the one with the M4". Arashi's M4A1 is fitted with a number of aftermarket parts, including its stock, rail system, and gas block, along with a SureFire foregrip/light combo and a red dot scope. One of the players who attempts to ambush Yamikaze is armed with an M4A1 fitted with an EOTech holosight and foregrip.
Norinco Model 311
BoB participant Kakouton attacks Kirito and Sinon with a Norinco Model 311; he reloads it with a Beta-C drum magazine when it runs empty.
Mk. 18 Mod 0
A Mk. 18 Mod 0 with tan furniture is seen held by Usujio Tarako during GGO the introductory sequence.
Heckler & Koch G36
A H&K G36 with the built-in 3x scope carry handle is seen when Kirito first enters GGO. The specific variant is unknown as the front end isn't seen.
Bushmaster ACR
A player is seen wielding a Bushmaster ACR in the market's firing range.
SIG SG 550
Dyne wields a SIG SG 550 as his main weapon, said to be a rare and good weapon in GGO.
FN F2000
XeXeeD is seen with an FN F2000 paired with the GL-1 under barrel grenade launcher and standard optical sight, said to be a rare and very good weapon in GGO. Sinon mentions that Yamikaze may be a more skilled player than XeXeeD, but the latter's F2000 and rare armour gave him the edge needed to win the previous BoB.
Battle Rifles
M1A SOCOM 16
A M1A SOCOM 16 used by Miso as his main weapon, correctly depicted as semi-auto only.
Mk 14. Mod 0
Musketeer X, a BoB competitor, wields a scoped Mk 14. Mod 0 as her primary weapon. Kirito later picks it up and uses it to provide cover fire for a downed Sinon.
Heckler & Koch G3A3
Uemaru wields a H&K G3A3 as his main weapon in the BoB preliminaries.
Machine Guns
FN Minimi
An enemy squad that Dyne's squad engages has a player armed with a FN Minimi to defend against enemy players, as the rest of their squad is armed with optical guns for fighting monsters. Its firepower is a plot point and the gun is called by name frequently.
M60E4
A player is seen with a M60E4 in the Bullet of Bullets qualifier room.
BoB tournament competitor Shishigane appears to be wielding a Browning M1919. The novels state he uses only a Jatimatic SMG (to save weight for other equipment, such as armor), however this weapon is clearly not that.
Vickers Machine Gun
Lion King Richie takes up a defensive position on a mountain with a Vickers machine gun during the BoB tournament.
M134 Minigun
The hired bodyguard Behemoth wields a hand-held M134 Minigun to counter Dyne's PvP squad.
Shotguns
Remington Model 870
A player is seen racking a Remington Model 870 in the Bullet of Bullets qualifier room.
Armalite AR-17
The agility-focused Pale Rider uses an Armalite AR-17 as his only weapon in the BoB tournament.
Sinon uses a PGM Hécate II as her main weapon. Shino treats her Hécate as an extension of herself and calls it by name often; it is an inseparable part of her Sinon persona.
MAS FR F2
The MAS FR F2 makes its anime debut as Sinon's main sniper rifle before she acquired her Hécate II. She's seen using the FR F2 about three months before the main story to defeat a large boss monster all by herself after accidentally running into it. Luckily for her, she could sit out if its effective range and simply snipe it to death, netting her the Hécate II as a reward.
Accuracy International Arctic Warfare Magnum
"Death Gun"'s main weapon is a suppressed Accuracy International Arctic Warfare Magnum. According to Sinon, it's called the "Silent Assassin" in-game for its attached suppressor and very good performance. In the novels it's expressly and repeatedly referred to by its British military designation of L115A3.
Unknown Rifle
A modern scoped rifle is seen held by an entrant in the BoB tournament.
Kirito uses a M18 smoke grenade picked up from Musketeer X to cover his and Sinon's escape from "Death Gun".
Plasma Grenade
A futuristic high-explosive grenade is used by Sinon to end the BoB Tournament.
Weapon Market
The weapon shop in GGO shows only silhouettes and images of the weapons available for purchase, with a weapon materializing upon being purchased by a player. As such, there is a large quantity of firearms that only appear in image form, and these are grouped here for the sake of not flooding the rest of the page with duplicate images and single-image entries.
Weapons shown in the market are grouped by weapon type, with pistols, SMGs/PDWs, assault rifles, shotguns, sniper rifles, rocket launchers, and hand grenades being shown.

SMG/PDWs:H&K XM8 Compact Carbine, H&K MP5A3, H&K MP5N with tactical light forend and reflex sight, KRISS Vector.
