Not eligible as a main article since it's a mobile game, so I'll work on it here. Some screencaps shown here are low quality, and I'm working on replacing them.
The following weapons appear in the video game Call of Duty: Mobile:
The "Renetti", a modified Beretta M9A3 from Call of Duty: Modern Warfare, was added in 2021 as part of Season 3: Tokyo Escape. It is depicted as firing in 3-round bursts by default (whereas its MW counterpart requires an attachment for that).
Custom Springfield Armory M1911
The "Bear Trap" Epic blueprint from Modern Warfare (2019) was added to CoD Mobile under the same name. It consists of the frame of a Kimber Custom TLE/RL II combined with an STI-like slide.
Additionally, the STI Tactical-style design seen on other Modern Warfare blueprints (regarding both the frame and the slide) is featured on the "Ghosts MW11" and "Federation MW11" charms. The "Double Tap" calling card (a returning one from MW, where it is labeled "Glimmering") features the "Corax" blueprint which, in addition to the STI design, has a SIG-Sauer 1911 style skeletonized trigger.
Desert Eagle Mark XIX
The slightly altered Desert Eagle Mark XIX from Modern Warfare (2019) was added in Season 12, retaining the ".50 GS" moniker. It uses the design of "Monochromatic" blueprint from MW, noted by the ".50AE" markings at the front of the barrel (though the "AE" part has been removed after an update); the "rubberized grip tape" used on that blueprint is visually present as well. Despite this, the CoDM version has a separate rubberized grip tape attachment that can be equipped alongside it.
The "J358" is a revolver loosely based on the Smith & Wesson Model 327 Performance Center M&P R8. By default, it has wooden grips, and holds 6 rounds, but can be upgraded with an 8-round cylinder (which matches the capacity of the real S&W Model 327). Prior to Season 9, it used .45 caliber ammunition in Battle Royale mode, but now it uses the generic "light" ammo for handguns and SMGs.
The gun's frame reuses that of the ".44 Magnum" from Call of Duty Online (a modified Smith & Wesson Model 629 Stealth Hunter). In the "One Shot One Kill" game mode, killcams involving the revolver previously displayed the icon of said ".44 Magnum" instead of the "J358" (the weapon has been replaced by the Desert Eagle after an update). Interestingly, one one of the barrel attachments, the "J358 Long", consists of a heavy barrel similar to that of a 629 Stealth Hunter.
The AA-12 from Modern Warfare (2019) was added in 2022 as part of Season 2: Task Force 141.
Browning Citori 725
A sawed-off and visually altered Browning Citori 725 appears as the "Shorty", under the pistols class. It was added in 2021 as part of Season 5: In Deep Water, and uses the model of the "CQBoom" blueprint from Modern Warfare (2019).
The Fostech Origin-12 was added in Season 10 under the name "Echo". It uses the model of the "Bloodlines" blueprint from Modern Warfare (2019), which has cosmetically different parts, including the handguard, receiver cover, magwell and trigger guard.
Two blueprints, the "Demon Eyes" and the "Sleeping Dragon", return from Modern Warfare. These ones use the design of the base MW version, being closer in appearance to the real Origin-12.
The "KRM-262" pump-action shotgun from Black Ops III was added to the game. The first version featured was the "Lava" Epic variant in Season 3, with a lava-style color scheme, as well as a muzzle brake that was not present on the BO3 model. In Season 8, the "base" version of the gun was added (without a hyphen in its name); it initially lacked the aforementioned muzzle brake, but this has changed in a later update.
The Winchester 1200 mentioned below has an Epic blueprint called the "Red Action", which is visually inspired by the "KRM-262", and was available before the KRM-262's addition to the game.
Sentinel Arms Striker-12 / Armsel Protecta Hybrid
The Sentinel Arms Striker-12 / Armsel Protecta hybrid from Call of Duty Online returns as the "Striker". This time, the (incorrect) use of the Striker-12's aperture button is omitted, and thus the player character is shown loading shells without rotating the drum.
SRM Arms Model 1216
Initially, it reused the Black Ops II model, with the player character rotating the magazine after each burst. However, in Season 9, the weapon was replaced by an inaccurate rendition, with the detachable magazine replaced by an internal one (therefore eliminating the rotating process while retaining the 4-round burst mode), along with a stock shaped similarly to a UTAS UTS-15, and a shortened top rail. The reloading process is done partly off-screen, in one motion.
Standard Manufacturing DP-12
A heavily modified Standard Manufacturing DP-12 was added in 2021 as part of Season 8: 2nd Anniversary, as the "R9-0". It uses the design of some blueprints from Modern Warfare (2019), such as the "Gold Dredge", having a noticeably altered appearance compared to a normal DP-12, with some visual cues that are somewhat reminiscent of the Kel-Tec KSG.
Winchester Model 1887
A heavily modified sawed-off Winchester Model 1887 appears as the "HS0405". It is fitted with rails that are similar to the Call of Duty Online version.
FN P90 TR
A modified FN P90 TR was added in 2021 as part of Season 10: Shadows Return, under the name "CBR4". It uses the model of "The Neutralizer" blueprint from Modern Warfare (2019), which has a Magpul PDR-C-esque thumbhole grip and trigger guard.
A similarly modified P90 with an integrated reflex sight is seen in the Season 12 comic. It uses the design of the "Mowed Down" blueprint from Modern Warfare which, in addition to the PDR-C style parts, has a long barrel and a handguard based on the PS90 M-LOK handguards from Dan Haga Designs.
The FN P90-based "Cordite" from Call of Duty: Black Ops 4 was added in Season 6.
The "PDW-57", another P90-based SMG previously appearing in Black Ops II, is featured in the game.
The "GKS", a submachine gun seemingly inspired by the POF PSG and previously appearing in Black Ops 4, was added in Season 5.
Heckler & Koch MP5A3
The Heckler & Koch MP5A3 was added in Season 7 as the "QQ9". It uses the model of the "Strapped" blueprint from Modern Warfare (2019), albeit with the sling removed. That blueprint essentially consists of an MP5A3 fitted with a handguard which is a hybrid between HK Parts MP5, 94 & HK53 Key Mod Handguard and Midwest Industries MP5 M-LOK handguard, and a top rail which for some reason is fitted with a quick detach lever from EOTech holographic sights, implying that the top rail can be removed quickly, though how exactly this could work in reality remains unfathomable.
The "Flood" is a returning blueprint from Modern Warfare. It received various changes for CoD Mobile, such as the charging handle being relocated to the rear.
Heckler & Koch MP7A2
The visually altered Heckler & Koch MP7A2 from Modern Warfare (2019) was added in Season 13 as the "QXR".
The "Flanker" blueprint of the "QXR" consists of a machine pistol fitted into a carbine conversion kit that is based on the CAA Tactical RONI.
The "HG 40", a futuristic MP40 from Black Ops III, appears in the game with even more alterations to the model.
The KRISS Vector Gen I / Gen II hybrid from Modern Warfare (2019) was added in Season 11 as the "Fennec".
The "Midnight" and "Royal Coffer" Epic blueprints are fitted with custom stocks via M4 stock adaptors. The "Ascended" Mythic blueprint has a customization option that makes it resemble the civilian Vector CRB Enhanced, albeit with a shorter barrel shroud.
The MAC-10 was added in 2022 as part of Season 3: Radical Raid. It uses the Black Ops Cold War model, which has a custom side cocking charging handle..
The Modern Sub Machine Carbine appears, using the Black Ops III model.
IMI Mini Uzi
The "Pharo" from Black Ops III, a Ruger MP9-based submachine gun firing in 4-round bursts, was added in Season 2.
Additionally, the "Scrap Metal" blueprint of the aforementioned MSMC is nearly identical to the "Pharo" visually, even having its "burst" switch above the trigger guard.
The PP-19 Bizon-2 from Modern Warfare (2019) was added in the 2021 Season 3: Tokyo Escape.
The "Razorback" from Black Ops III, a submachine gun bearing a resemblance to the fictional "Thor PDW", was added in Season 2.
Rifles & Carbines
The modified AK-102 from Call of Duty Online returns as the "AK117".
The AKM appears, referred to as the earlier AK-47, and using the Call of Duty Online model. As a result, it is depicted with three rivets at the rear of the receiver (like AK variants with side-folding stocks, such as the AKS-74 and the AK-100 series), and the fire selector is incorrectly set to semi-auto.
The "Life and Death" blueprint is an AK-47 with a shortened barrel and gas system. It uses the model of the "Brick Wall" blueprint from Black Ops Cold War, with a few alterations.
Additionally, the Modern Warfare (2019) "Protector" calling card featuring a full-sized AK-47 returns in CoD Mobile under the name "Rugged". AK-47s with altered receivers are seen in the Season 12 comic as well.
The "Metallic Mist" blueprint uses the model of an AKS-74U lookalike created from the AK-47 in Call of Duty: Modern Warfare (2019), with a blue finish. Given the different model reused compared to the base CoDM version, the fire selector is appropriately set to full-auto, and the 5.45x39mm magazine is modeled correctly.
The "Kuromaku" Mastercraft variant of Black Ops 4’s "KN-57" (based on the 2015 prototype of the AK-12) was added to Call of Duty: Mobile as a Legendary blueprint for the "AK-47". A previously added blueprint, the "Pumpkin Head", is also based on that "KN-57".
The heavily modified AKS-74U from Call of Duty Online appears, still classed as a submachine gun. The in-game name was changed from "AKS-74U" to "RUS-79U" in Season 3.
The modified AKU-94 from Call of Duty Online returns as the "BK57".
The "Gimmick" blueprint of the "BK57" is modeled after the Vepr from Call of Duty Online, with a custom finish.
The AN-94 appears as the "ASM10" (named similarly to the Thompson-based "ASM1" from Call of Duty: Advanced Warfare). It uses the Call of Duty Online model, which has a prototype AK-12 style fire selector, and a magazine inserted vertically rather than being slightly canted to the right.
The AS Val from Modern Warfare (2019) was added in 2021 as part of Season 2: Day of Reckoning.
Similarly to its MW counterpart, the AS Val can be visually turned into a VSS Vintorez, in this case with the "RTC Steady Stock". The resemblance can be further increased with the "15 Round FMJ" magazine (originally 10, but buffed to 15 after an update) and with one of the scope options. The "OWC Ranger Stock" approximates the modernized VSSM.
Also like in Modern Warfare, SR-3/SR-3M Vikhr-like configurations can be made with the weapon.
A custom AR-15-patterned rifle appears as the "M4". It consists of a hybrid upper receiver with its right side being from VLTOR MUR while the left is similar to Cross Machine Tools receiver with grooves like JP Enterprises CTR-02, a Geissele Super Dynamic trigger, a Magpul trigger guard and a Magpul pistol grip. It has a handguard which appears to be a hybrid between the HWK KeyMod Free Float Handguard, Titan Handguard and Fortis Night Rail, and a stock that appears to be a hybrid between a Magpul MOE SL and a Steyr AUG's stock. It also has a Raptor charging handle, a shark style muzzle brake and the magazine looks like it has a built in plate similar to the UTG polymer magazines.
The "Enchanted Carbine" Epic blueprint is based on the "M4A1 Tech" from Call of Duty Online, consisting of an HK416's upper receiver mated to an M4A1's lower, along with an HK416 A5 style trigger guard.
"The Breakup" is a returning blueprint from Modern Warfare (2019). It consists of that game's "M4A1" (actually a Colt Model 933) fitted with a carrying handle and a Magpul-style stock, combined with an M16A4-style barrel and handguard (with the barrel depicted with an M203 groove, like an M4), as well as a compensator. The .458 SOCOM magazine seen on MW’s blueprint now acts as a 40-round magazine extension.
The "Vengeance" blueprint uses the design of some blueprints from Modern Warfare (such as the "Soulful Wanderer"), having a Radian Weapons-based receiver, with the left side of the upper resembling the Mega Arms MATEN or Cross Machine Tools upper, along with grooves from the JP Enterprises CTR-02.
A modified FAMAS F1 was added in 2021 as part of Season 1: New Order. The design is the one used by the "Desert Rat" and "Bubble Burster" blueprints from Modern Warfare (2019), albeit with a standard finish and barrel length. It is called "FR .556", which is the same absurd name that was seen in pre-release footage of Modern Warfare.
The "Insurgency" is a returning blueprint from Modern Warfare, being a FAMAS Valorisé with some cosmetic modifications.
The FN SCAR-H was added in Season 8 as the "DR-H". It uses the model of "The Traitor" blueprint from Modern Warfare (2019), which has an altered receiver, a rail extension, and a stock inspired by a Bushmaster ACR's folding stock.
The "Mother of Pearl" blueprint uses the model of the base MW version with the installed “FORGE TAC 17.2" LB” attachment.
The "Sludge" blueprint returns from Modern Warfare, resembling the compact FN SCAR-SC but retaining the SCAR-H's 7.62x51mm magazine.
The "HBRa3" from Advanced Warfare, a futuristic assault rifle based on the Robinson Armament XCR, was added to the game in Season 3.
Heckler & Koch G36
The "Holger-26" from Modern Warfare (2019), a Heckler & Koch G36 ostensibly set up to pass for an MG36, was added to the light machine guns class in 2021 as part of Season 4: Spurned & Burned. This time, it lacks a hyphen in its name.
Heckler & Koch G36K
Just like in Modern Warfare, the weapon can be visually turned into a G36K, in this case with the "MIP Light" barrel attachment.
Heckler & Koch G36C
The "MIP Light Barrel (Short)" turns the gun into a G36C.
The "LK24" assault rifle is a heavily modified Heckler & Koch G36K, taking some minor design cues from the "G37H" seen in Call of Duty Online. It lacks a carrying handle, and has a custom handguard, telescoping stock, pistol grip and trigger guard, as well as an AR fire control group. Such fire control lowers are available for G36 rifles in reality, being manufactured by Tommy Built Tactical, but they have H&K style bullet pictograms, whereas the in-game version has "Safe" and "Semi" markings.
Of note is that the "Rusted Shroud" blueprint is actually modeled after Online’s "G37H", albeit with an orange finish.
Heckler & Koch HK433
The Heckler & Koch HK433 prototype from Modern Warfare (2019) was added in the 2022 Season 1: Heist. It retains the "Kilo 141" moniker, and uses the finish of the "Kilobite" blueprint from that game.
The "HVK-30", a carbine that appears to be a futuristic FN FAL derivative, returns from Black Ops III. It was added in Season 5.
In addition, the "Sickle" blueprint of the aforementioned "M4" looks very similar to the "HVK-30"; it reuses the model of one of the cosmetic variants of the "M4A1 Tech" from Call of Duty Online.
The "ICR-1" from Black Ops III, a futuristic assault rifle based on the Heckler & Koch HK416, was added in Season 2.
IWI Galil ACE Hybrid
The "CR-56 AMAX" from Modern Warfare (2019), a 7.62x39mm IWI Galil ACE hybridized with the 11.8" barrel of a 7.62x51mm Galil ACE GAR51SBR, was added in the 2021 Season 5: In Deep Water.
Just like in Modern Warfare, it can be fitted with a more appropriate Galil ACE GAR39SBR's 8.3" barrel (this variant being actually chambered in 7.62x39mm). It can also be modified with a barrel and folding stock reminiscent of the original IMI Galil (albeit with a Beretta AR-70/223-like handguard).
The Karabiner 98k was added in Season 9, under the name "Kilo Bolt-Action"; it was the first weapon to appear in the marksman rifles class. It uses the Modern Warfare (2019) model, but with the sling removed; the sling slot and the bolt disassembly disc are also missing from the stock.
The "Rail Gun" Legendary blueprint is a futuristic Kar98k modified into a rail gun.
The AK-200-esque "KN-44" from Black Ops III was added in Season 4. Additionally, the aforementioned AKM has a blueprint called the "Red Action", which is based on the "KN-44", and was available before the KN-44's addition to the game.
The M16A4 appears simply as the "M16". It uses the Modern Warfare Remastered model with some minor differences, such as the lack of a tape on the magazine.
The "FUBAR" blueprint adds an M203 grenade launcher heat shield, a magazine tape, a vintage US military style olive drab paintjob and a suppressor. The "Heavy Duty" blueprint is a fictional custom built AR made from tools with a pipe wrench for stock. The "Valentine" blueprint is the AR with a custom chassis and muzzle; it also has the same pseudo SENTRY's Hexmag magazine with a stylized Magpul Ranger Plate.
"The Stripe" blueprint is an M16A2 with a custom camo and a proper barrel. It is a returning blueprint from Black Ops Cold War.
The "Man-O-War" from Black Ops III was added in Season 2. One of its blueprints, the "Cardinal", is modeled after one of the cosmetic variants of the SCAR-H from Call of Duty Online.
Marlin Model 1895
The Marlin Model 1895 from Modern Warfare (2019) was added to the marksman rifles class in the 2021 Season 4: Spurned & Burned, under the name "MK2". By default, it is modeled with the “FSS 24.0" Factory” extended barrel from MW. In contrast to that game, it has an attachment that allows it to use the smaller-caliber .30-30 cartridge (the latter being used by the Marlin Model 1893 and Model 336 in reality).
The "Peacekeeper MK2" from future-era Black Ops games was added in Season 13. This specific designation was used in Black Ops III, but the weapon actually uses the design of the "Peacekeeper" from Black Ops 4, which is nearly identical to the BO3 counterpart, but has some tiny differences such as the serial number.
SIG-Sauer MCX VIRTUS SBR
The SIG-Sauer MCX VIRTUS SBR from Modern Warfare (2019) was added in the 2021 Season 8: 2nd Anniversary as the "M13".
Steyr AUG A3
A visually modified Steyr AUG A3 was added to the submachine guns class as the "AGR 556". It uses the model of the "Airshot" blueprint from Modern Warfare (2019), which has a different stock and a railed handguard. When the weapon was added in Season 12, it was modeled with a 5.56x45mm magazine by default like a standard AUG A3 assault rifle, despite being in the SMG category and having the option to be converted to use 5.56mm ammunition in different-looking magazines.
In Season 13, the "AGR 556" got modified with a custom magwell and an SMG-sized magazine, both looking different from AUG submachine gun variants. When a 5.56mm conversion attachment was used, said magwell used to be retained (resulting in the 5.56mm magazine clipping through it), but this was later fixed.
The "Matchstick" and "Al Rukh" blueprints using 5.56mm magazines have proper AUG A3 stocks. They are returning blueprints from Modern Warfare; the former is fitted with a top rail similar to the civilian AUG A3 M1, while the latter has an AUG A3 M1-like flash hider and an AUG A3 SF-style scope.
The "Swordfish" from Black Ops 4, a burst-firing bullpup rifle taking cues from the Vektor CR-21 and the FN F2000, was added in 2021 as part of Season 9: Nightmare. It fires in 4-round bursts by default, but the "Halberd Mag" attachment changes the fire mode to 5-round burst.
The "Type 25", a futuristic QBZ-95-1 from Black Ops II (with an original QBZ-95 style trigger guard), appears in the game. It previously used 5.56mm ammo in Battle Royale (which is used by the QBZ-97 in reality), but now it uses the generic "heavy" ammo for assault rifles and LMGs.
IMI Tavor MTAR-21
The "Demise" blueprint of the "Type 25" is modeled after a Micro Tavor MTAR-21. It uses the model of the "Tavor-21 Tech" from Call of Duty Online, which has a longer barrel and a modified stock.
The Zastava M59/66 from Modern Warfare (2019), which has a furniture similar to the Tapco Intrafuse Stock System, was added in the 2021 Season 1: New Order. Like in that game, it is referred to as the "SKS", and appears under the marksman rifles class.
Accuracy International AS50
The Accuracy International AS50 appears as the "Arctic .50", using the Call of Duty Online model.
The Barrett XM109 from Modern Warfare (2019), a hybrid of the earlier and the later model, returns as the "Rytec AMR". It was added in 2021 as part of Season 6: The Heat.
The "DL Q33" is a fictional bolt-action sniper rifle with possibly some minor inspiration from the Cheyenne Tactical M200 Intervention seen in previous games, along with a few parts reminiscent of the Cadex Defence Dual Strike Chassis.
The "Fatigue" blueprint is modeled after one of the cosmetic variants of the Remington MSR from Call of Duty Online. It has an MSR-style handguard, and the receiver takes various visual cues from the "D-25S", an FD308-based sniper rifle from Modern Warfare Remastered. It also has a Tyrant Designs skeletonized pistol grip.
The "Koshka" from Black Ops 4, a bullpup bolt-action sniper rifle resembling the SVU, was added in 2022 as part of Season 4: Wild Dogs.
The "Locus", a futuristic sniper rifle based on the PGM Mini-Hecate and previously appearing in Black Ops III and Black Ops 4, was added to the game in Season 2. It specifically uses the BO3 design.
The "Flesh Wound" blueprint is a modified M14 with a shorter barrel. It is a returning blueprint from Modern Warfare (2019), having a stock that seems to be a hybrid of an Archangel chassis and Magpul's Remington 700 stock.
In addition, full-sized M14 rifles are seen in the Season 9 comic.
The M24 SWS from Modern Warfare (2019) was added to the marksman rifles class in the 2021 Season 2: Day of Reckoning, as the "SP-R 208".
The "NA-45" from Advanced Warfare was added in Season 11.
The "Outlaw", a bolt-action revolving (yeah...) sniper rifle seemingly inspired by a Blaser R93 and previously appearing in Black Ops 4, was added in Season 6.
The SVD Dragunov from Modern Warfare (2019) was added in the 2021 Season 10: Shadows Return as the "SVD".
The "XPR-50", a semi-automatic sniper rifle somewhat resembling the bolt-action Barrett Model 98 Bravo, returns from Black Ops II and Black Ops III. It specifically uses the BO3 model.
DS Arms RPD
The altered DS Arms RPD from Call of Duty Online appears as the "RPD".
The "Wave Lord", a returning blueprint from Black Ops Cold War, is a standard RPD with some accessories and a custom finish.
The "Hades" from Black Ops 4, a machine gun resembling the Mk 48 Mod 0 but with the depiction of a helical feeding mechanism, was added in 2021 as part of Season 7: Elite of the Elite.
The Knight's Armament ChainSAW was added in Season 7 as the "Chopper". Its model was taken from Call of Duty: Ghosts, though the proper circular vent holes have been replaced by elongated ones. Furthermore, the only parts remaining from the underslung Spike's Tactical "Havoc" flare launcher are the mount and the receiver; the barrel assembly has been replaced by some kind of rail system. The "Chain Reaction" Legendary blueprint of the "Chopper" does have a Havoc underbarrel launcher attached, albeit still unusable.
In Season 9, with the introduction of Gunsmith, the weapon got modified with a pistol grip and a stock, allowing it to be properly aimed by default. However, it retains the KAC ChainSAW's unique lower receiver (rather than making it akin to the original KAC LMG), resulting in a bulky appearance. Equipping the "heavy handle" attachment re-adds the chainsaw grips.
The "Klondike" and "Become War" blueprints are modeled after the "FiNN LMG" from Modern Warfare (2019), a modified Knight's Armament LAMG. Additionally, the "Firewall" blueprint is a KAC LAMG fitted with KAC ChainSAW-style grips
A heavily modified L86A1 appears as the "UL736". Its design is similar to the modified L86A2 from Call of Duty Online.
The "X Marks the Spot" blueprint uses the design of the L86 from Modern Warfare (2019), which is much more accurately modeled, albeit still having a few differences compared to the real weapon, such as an L85-style handguard.
The "M4LMG", a squad automatic weapon seemingly based on a Barrett REC7, returns from Call of Duty Online.
Norinco QJB-95-1 / QBZ-97 Hybrid
A hybrid of the QJB-95-1 and the QBZ-97 appears as the "S36", being based on the futurized QJB-95-1 from Black Ops II. It has a selector switch above the pistol grip like the QJB-95-1, but feeds from AR-15 style magazines like the QBZ-97 (and the QJB-97), as well as having a QBZ-95/97 style trigger guard.
The PKM from Modern Warfare (2019) was added in 2021 as part of Season 11: Final Snow.
The "FHJ-18 AA" from Black Ops II appears with a new model, and with the "AA" suffix removed from the name.
M79 grenade launcher
The M79 grenade launcher was added in the 2021 Season 9: Nightmare as the "Thumper". It uses the Black Ops Cold War design with a few differences.
The Pansarskott m/86 from Call of Duty Online returns as the "SMRS".
The Taurus Raging Bull-based "Annihilator" from Black Ops III was added in Season 6, and is still used in single-action mode.
In Season 7, the Battle Royale version gained the ability to be reloaded. This is done while the hammer is still cocked, something not possible on real similar revolvers.
Fictional Machine Pistol
The "Ballistic Shield" operator skill comes with a futuristic machine pistol. It previously appeared in Call of Duty: Black Ops 4, and was added to Call of Duty: Mobile in Season 12.
Handheld General Dynamics GAU-19/A
The futuristic handheld General Dynamics GAU-19/A from Black Ops II returns as the "Death Machine". It is available as an "operator skill", and is also equipped on the "XS1 Goliath" armor killstreak.
The "War Machine" is a futuristic grenade launcher based on the Milkor MGL Mk 1L.
In Season 11, the Battle Royale version gained the ability to be reloaded, in which case the whole cylinder is detached and replaced.
"Cluster Smoke Grenade"
The "Cluster Smoke Grenade" is a fictional smoke grenade loosely based on the M47 CS grenade. It is exclusive to Battle Royale mode, and is available to the Smoke Bomber class.
M84 stun grenade
The same futurized M84 stun grenade from Black Ops II returns, once again serving as the base model for two grenades, "Flashbang Grenade" and "Concussion Grenade".
The Browning M2HB is available for use on the pseudo PL-01 tanks added to Battle Royale in Season 7. It is referred to as "Tank Machine Gun".
It also became usable in the regular multiplayer in Season 9 as the "Shield Turret" scorestreak, reusing the model from Modern Warfare (2019). Said "Shield Turret" later became available in Battle Royale in the 2021 Season 1: New Order, for the Desperado class.
In the "Tank Battle" gametype of Battle Royale (released in the 2021 Season 2: Day of Reckoning), tank-mounted M2s are also available with a "Purifier" flamethrower modification or a "War Machine" grenade launcher modification.
FIM-92 Stinger Dual Mount System
The same mockup of the FIM-92 Stinger Dual Mount System seen in Call of Duty: Black Ops and Call of Duty Online appears as the SAM Turret scorestreak. It is also seen in the practice range (the latter having been added in Season 7), where it is used to rather comically launch rockets at an impossible angle and absurdly slow speed as to emulate skeet shooting.
General Dynamics GAU-17/A
In the Zombies mode Undead Siege, the "Heavy Sentry Turret" consists of twin-mounted and shortened General Dynamics GAU-17/A rotary guns. Each one is depicted with five barrels instead of six.
General Dynamics GAU-19/A
A tripod-mounted version of the previously mentioned GAU-19/A is used for the unmanned sentry gun killstreak. The gun is also mounted on the "Antelope A20" assault vehicle in Battle Royale mode.
General Dynamics M197 Vulcan
The General Dynamics M197 Vulcan is the chin armament of the "Stealth Chopper" scorestreak, a fictional helicopter based on the RAH-66 Commanche.
Unusable low poly machine guns seemingly supposed to represent the M240D can be seen mounted on some static tanks.
The "D13 Sector" from Black Ops III was added in the 2021 Season 11: Final Snow.
Hybrid Reverse Draw Crossbow
The reverse draw crossbow from Modern Warfare (2019), which is a hybrid of the Barnett Headhunter and the Scorpyd Aculeus crossbows, was added in 2021 as part of Season 7: Elite of the Elite.
A different crossbow is strapped to the back of Seraph's "Gravekiller" skin.
The "Ray Gun" from the Black Ops franchise is available in Zombies mode (introduced in Season 2).
Arsenal Firearms Strike One-style pistol
The "Lightgun Trainer" and "Bubblegun" calling cards feature an Arsenal Firearms Strike One style pistol. Said design is seen in Modern Warfare (2019) on some blueprints of the Glock 21, such as the "Urban Defiler".
Heckler & Koch USP
A Heckler & Koch USP is holstered by Thomas Merrick. It is also seen on some Mil-Sim operators skins.
The futurized KRISS Kard from Black Ops II is seen in the 2021 comics of Season 7: Elite of the Elite and Season 10: Shadows Return.
A pair of LeMat 1861 revolvers are seen on the "Deadshot" and "Funny Bone" sprays. Their design is the same as the "M1 Irons" from Call of Duty: Advanced Warfare, with a top rail.
A Remington 1858 revolver is seen in the "Cyborg Showdown" calling card.
Single Action Army
A Single Action Army is seen in the Battle Pass comic of Season 6.
