Revision as of 20:57, 3 November 2016
Work In Progress
This article is still under construction. It may contain factual errors. See Talk:Payday 2 for current discussions. Content is subject to change.
Payday 2 is the sequel to Payday: The Heist. As with the first game, players may join up to three others in a spree of robberies and other heists to earn money. Payday 2 noticeably features many changes from the first game, among other things the new skill tree. Each of the five trees (the Mastermind, Enforcer, Technician, Ghost, and Fugitive) focuses on differing specializations, though unlike the first game do not grant new weapons for level ups (aside from special examples like the portable saw). Weapons are instead unlocked to purchase by leveling up, which now is done with experience points instead of money. Money is used to buy new weapons, modifications, and masks, though it is divided between a player's "Offshore Account" (which comprises 80% of the money they earn in a heist) and spending cash (the other 20%), and only the spending cash can be used to buy weapons and addons.
Entries marked with (*) are weapons obtained for free (although they still need to be bought with in-game money) by joining the official Payday 2 steam group. Entries marked with (**) are DLC (downloadable content) weapons.
The following weapons appear in the video game Payday 2
The game operates with the heister moving in with 2 weapons, and 2 weapons only. A primary and a secondary. Primaries consist of assault and battle rifles, shotguns, sniper rifles, machine guns, and dual-wielded weapons. Secondaries consist of pistols, machine pistols, and bizarrely, a few chopped down variants of some shotguns and assault rifles. Players can take ammo from enemies, but not weapons, ala SWAT 4 and other such tactical shooters.
Each weapon has its own customization options, though some like the Glock 17 barely have any and others like the M4A1 may have much more than others. In addition to shared items like suppressors, weapons also have their own sets of unique addons, such as extended magazines or different finishes or grips. Mods can be removed from these weapons for no charge, and the mod in question will not be lost, merely returned to the player's inventory. However, re-adding it will again require money, with the exception of certain items that have no cost to add
In addition to this, the Gage Weapon Pack #01 DLC introduced select-fire to weapons, and DLC owners unlock access to special addons that enable locking a weapon permanently in one fire mode, along with frag grenades. The later Gage Weapon Pack #02 DLC introduced machine guns and knives to the game. Owners of the Gage Mod Courier DLC are able to unlock a special set of free modifications that are otherwise unobtainable. As a bonus, the pack also comes with extra reticles and colors for all sights, though players without the DLC will still be able to use all the colors and a few of the new reticles. In addition, every weapon DLC pack since (and a few heist DLCs) have had even more new guns and melee weapons, and some lock weapon addons to specific achievements rather than random drops. The Gage Sniper Pack introduced armor-piercing sniper rifles to the game. Finally, a noteworthy addition from the Gage Shotgun Pack DLC is the option to use different shell types for any of the game's shotguns. All firearms in Payday 2 are capable of performing a "tactical reload" (i.e. reload when the magazine isn't emptied) in addition to the "dry" animation, though as is common with most contemporary non-tactical shooters, none of them retain the round currently in battery, meaning there is no "one round in the chamber".
The October 22, 2014 patch introduced akimbo weapons, which are wielded as primary weapons but are mostly identical to their single-wielded versions (aside to obvious penalties to their accuracy and recoil control). This list of weapons has expanded over time to include seven sets of pistols and three sets of sub-machine guns. Formerly, only players that had the Hitman perk deck or the Akimbo skill were able to use these weapons, though as of Update 100 (June 2, 2016) any player may use them without any skill investment at all
As of Update #65 (The first person animation update) All base game guns (except for the Taurus Raging Bull aka Bronco .44) and some DLC weapons have received new first person animations, most notably new reloading animations. Also with this update magazines now actually have fully modeled bullets in them, on top of that, it's is possible to see the bullets in the transparent magazines of weapons such as the JP36 (G36K), Commando 553 (SG 552-2), Kobus 90 (P90) etc.
Handguns
As of update 61, it is now possible to dual-wield (or Akimbo) a select few of the handguns in-game. The Akimbo handguns are used as primary weapons. It is not possible to akimbo all handguns or a combination of two different pistols.
The handguns that can be dual-wielded are listed below in their respective entry.
Glock 17
The first weapon the new players can use (alongside the Colt Model 733) is a Glock 17. It is given to the player for free as soon as they start the game. It goes by the name "Chimano 88" in-game (the 88 possibly being a reference to Pistol 88, the Swedish army's designation for the Glock 17, which is their service weapon) In the early days of Payday 2, it could only use one of three suppressors, though additional mods compatible with it has since been added. The mod selection for the Glock 17 is strangely limited. It can't, for example, use the extended magazine the Glock 18 and 22 can use for whatever reason.
It has damage and accuracy stats very slightly below most 9mm pistols in the game but it boasts a huge ammo pool and top notch concealment. The pistol has a 17 round magazine capacity which would be correct if it weren't for the extended base plate that should add two more rounds, but it doesn't.
It is one of seven pistols that can be dual-wielded.
Akimbo
Springfield Armory 1911 Lightweight Operator
The Springfield Armory 1911 Lightweight Operator is unlocked at reputation level 2, and is much more customizable than the starting Glock 17. It goes by the name "Crosskill" as in the first game. The pistol holds 10 rounds in a 7 or 8-round magazine. Modifiying the pistol with the "12rnd Mag.", modeled off the extended Kimber 10-round magazine, will actually give it a 16 round capacity.
Akimbo
Beretta 92FS Centurion
The Beretta 92FS Centurion appears as the "Bernetti 9" and is unlocked at level 6. It has an incorrect 14-round capacity instead of 15. The name "B9-S" is visible on the slide, as a nod to the pistol's name from the first Payday.
Akimbo
Taurus Raging Bull
The Taurus Raging Bull returns from the first Payday, again known as the "Bronco .44" but now featuring its full-length barrel by default. It holds 6 rounds and is unlocked at level 6. An early patch added street cops carrying this weapon. It is also notably used by the female FBI Agent enemies in the Hoxton Breakout heist and some mobsters in the Hotline Miami heist.
Glock 18C
The Glock 18C is unlocked at level 29 and, similarly to its appearance in the first game's "Wolf Pack" DLC, is known as the "STRYK 18c" (Stryk is swedish and can be translated as "beating") It still features a high rate of fire, decent damage, and low accuracy. It holds 20 rounds in a 19 round magazine. Notably, it is one of three non-LMG guns in the game that cannot equip modifications to lock it in one firing mode, and one of the two among them that is capable of selective fire.
IMI Desert Eagle Mark XIX
The IMI Desert Eagle Mark XIX goes by the everlasting nickname "Deagle" in-game. It holds an incorrect 10 rounds in its 7-round magazine. While it's possible to squeeze ten rounds into the .357 Magnum version of a Desert Eagle (nine in the mag and a round in the chamber) the Desert Eagle in-game is clearly the .50 AE version since it has a non-fluted barrel.
Akimbo
Heckler & Koch USP45 Tactical(*)
The Heckler & Koch USP45 Tactical appears as the "Interceptor .45" and is automatically unlocked for purchase by joining the official Payday Steam Group. It's quite powerful and uses a 13-round magazine (one more than it holds in real life for the .45 ACP version).
Akimbo
Glock 22C(*)
The Glock 22C was added in the Election Day update and is named the "Chimano Custom" It has a default magazine of 16 rounds (actually 15 in real life or 17 with the +2 base-plate shown in-game) and can be modified in most of the same ways as the Glock 18C.
Akimbo
Glock 26(*)
On the seventh day of the Crimefest release parade (October 22nd 2014), John Wick himself jumped aboard and brought his trusted Glock 26 along for the ride. Called the Chimano Compact, it tries to fill the same "high-capacity 9x19mm" role as the Beretta 92. It can stand up to it in terms of damage output and has a trivial recoil advantage, but otherwise lags a little behind on all fronts, especially so with the "high-capacity" bit. Unlocked at level 36, the $605,000 price tag is a little hard to swallow for what it is. It's also the first of the seven pistols which have separate akimbo variants classed as primary weapons.
Akimbo
Walther PPK(**)
The Walther PPK is available for purchase with the Armored Transport DLC and is known as the "Gruber Kurz" pistol. It is fairly weak but easy to conceal and incorrectly holds 14 rounds instead of 6 (.380 ACP) or 7 (.32 ACP) rounds. It was the first handgun in the game to be able to use a laser without needing anything in the gadget slot, having a unique grip with a built-in laser. This was later followed by the Glock series' own laser grip
SIG-Sauer P226R(**)
The SIG-Sauer P226R in .40 S&W appears as the Signature .40 and is unlocked for purchase by buying the Gage Weapon Pack #01 DLC. In-game it does the same amount of damage as the Crosskill (Springfield Armory 1911 Lightweight Operator), but most, if not all, of its stats are better compared to the Crosskill. By default, the P226 holds 12 rounds (one less than the real .40 version) and its extended magazine unusually has no concealment penalty (unlike those for most weapons)
Taurus 4510PLYFS(*)
The Taurus 4510PLYFS was added to the game as a Crimefest community milestone reward, for having 1 million members in the Payday 2 Steam group. It shoots the .410 Bore and holds 5 shells, and is classed by the game as a shotgun, so handgun skills have no effects on it. It is depicted as being ridiculously power, even more so than most of the 12 gauge shotguns, despite it's .410 chambering, much like the similar Taurus Judge in the Max Payne movie. Thanks to sharing its accessories with the other shotguns, it can accept the Silent Killer suppressor, which logically wouldn't work due to the gap between the barrel and cylinder.
Mauser C96 "Broomhandle"(**)
The Mauser C96 appears as the "Broomstick" and is unlocked for purchase at level 23 if one owns the Gage Historical Pack DLC. It has rather high damage (equivalent to the 92FS Centurion or PPK), but is hindered by its 10-round magazine and a somewhat slower reload.
Springfield Armory XDM(**)
The Springfield Armory XDM appears as the "LEO Pistol" as part of the Butcher DLC. Initially a Croatian design (as the HS2000), it has an 19-round magazine, which is correct for the 9mm version. The markings are inconsistent however, showing on the slide that the chambering is .40 S&W, but the ejection port markings show that is chambered for .45 ACP.
The pistol has an olive drab frame.
Single Action Army(**)
A Single Action Army with wooden grips appears as the "Peacemaker .45" and is part of the "Butcher's Western Pack" DLC. It deals a rather ridiculous amount of damage per shot, more than the Desert Eagle and Raging Bull.
Mateba 2006M(**)
The Mateba 2006M was added into the game with the Alesso Heist DLC. It's called "Matever .357" in game, a reference to the butchering of the manufacturer's name in the English dub of Ghost in the Shell.
IWI Jericho 941 PL(**)
The IWI Jericho 941 PL was be added in the Point Break heists DLC. It's called "Baby Deagle" in-game, referencing Magnum Research's marketing of the Jericho as a "Baby Eagle". The weapon has the ejection port marked as 9x19 (9x19mm Parabellum), however it has a magazine capacity of 12 rounds, indicating a .40 caliber variant. The standard 9mm variant has a capacity of 15 rounds. Additionally, the Jericho has the silver guide rod of the 941's chambered in .41 AE. To confuse these caliber matters more, the pistol deals around a whooping 150 damage per shot unmodified, The same as the .50 AE Desert Eagle in-game.
Kalashnikov Concern PL-14 Lebedev
The Russian PL-14 Lebedev prototype pistol is another weapon added for free with the Hardcore Henry Packs DLC and is called the "White Streak Pistol" in-game. It is incorrectly depicted with a 12-round magazine capacity instead the real life 15-round capacity, even with its "Extended Magazine" mod it only brings it to 14 rounds. Judging from its ridiculously high Desert Eagle level damage it seems to be chambered in a caliber far larger than 9x19mm (which is the only caliber available), the capacity and high damage show that its stats are a copy-and-paste of the Jericho 941 RPL's stats.
Heckler & Koch P30L(**)
The Heckler & Koch P30L was added along with the "John Wick Weapon Pack" It's known as the "Contractor Pistol" in-game.
Akimbo
Submachine Guns
The Hardcore Henry update added the ability to Akimbo two SMGs. The dual-wielding works the same as with the pistols, with the two guns being used as a primary weapon.
The SMGs that can be dual-wielded are listed below in their respective entry, except for the AKMSU. That entry is found in the rifles category.
Ingram MAC-11
The "Mark 10" is actually based on a Ingram MAC-11 and a cheap Double Eagle airsoft one at that. It is unlocked at reputation level 2. It holds an incorrect 40 rounds in a short 16-round MAC-11 magazine and the Extended Magazine attachment gives it a 32-round magazine that increases the capacity to 48.
Heckler & Koch MP5
The Heckler & Koch MP5 returns from the first Payday, again known as the "Compact-5". It is unlocked at level 13 and can be modified into many different MP5 models.
Akimbo
Brügger & Thomet MP9
The B&T MP9 appears as the "CMP" and is unlocked at reputation level 19, in reference to the Steyr TMP lookalike in the Nintendo 64 title Perfect Dark. It has an unfortunate niche in the stat rankings where it's not able to muster enough brawn to plug heavier SWAT in single headshots, but isn't quite small enough to pocket for stealth tasks either. What makes it such a hidden gem are the terrific accuracy and stability for its fire rate, which mean that it can put three rounds into a helmet where other SMGs could only place one before jumping off mark. The quick reload, deep ammo pool and agreeable hipfire performance are just further perks.
FN P90 TR
The FN P90 TR appears as the "Kobus 90" and is unlocked at reputation level 36. It has the highest magazine size of any secondary, but only comes with a total of three mags. If the Long Barrel mod is put on the gun, it will resemble the PS90 TR, the civilian carbine version. As of the First Person Animations Update, the P90's magazine is now translucent and visibly empties as the gun is fired
Thompson M1928(*)
The Thompson M1928 with a 50-round "L" drum magazine was added in the December 3, 2014 patch and is unlocked at level 14 for members of the Payday 2 Steam group. Along with the P90, it has the highest magazine size of any SMG in the game, but its accuracy and damage are rather low without modifications. It is one of 3 select-fire guns (one of two secondaries, alongside the Glock 18) that does not get the fire-mode locking mods.
Carl Gustav M/45(**)
The Carl Gustav M/45 is named the "Swedish K SMG" in game and incorrectly holds 40 rounds in the magazine instead of 36. It is available for purchase to anyone who owns the "Armored Transport" DLC. The in-game weapon is based on the military version of the M/45, as evident by the lack of a fire selector.
Heckler & Koch MP7A2(**)
The Heckler & Koch MP7A2 appears as the "SpecOps" and is unlocked for purchase by buying the "Gage Weapon Pack #01" DLC. It holds 20 rounds in its standard flush maganine.
Sa. Vz.61 Skorpion(**)
The Sa. Vz.61 Skorpion appears as the "Cobra" and is unlocked for purchase by buying the "Hotline Miami" DLC.
Intratec TEC-9(**)
An Intratec TEC-9 modified to allow for fully-automatic firing appears as the "Blaster 9mm" and is unlocked for purchase by buying the "Hotline Miami" DLC. It holds 20 rounds by default and it's Extended Magazine modification gives it a correct 32 rounds.
In-game, it operates in strange ways uncharacteristic of the real TEC-9, the weapon fires from a closed bolt, meaning that it could be based on the US-import KG-9 model. The KG-9 was forced to be converted to a closed-bolt firearm by the Bureau of Alcohol, Tobacco and Firearms and Explosives (ATF) before the weapon could be marketed in the United States. The closed bolt would make the full automatic conversion unfeasible, which is an intended feature of the forced redesign as to discourage users from illegally modifying their TEC-9s. It is also capable of selective-firing, which is a highly unusual trait, that few illegal gunsmiths would implement into a weapon when converting from semi to fully-automatic. This also suggest that the Blaster could be partially based on the Interdynamic MP9, the parent design of the TEC-9.
However, Payday 2 depicts several open-bolt firearms (the MAC-10, Uzi, AA-12, M/45) as firing from a closed bolt, so the TEC-9 having a closed-bolt in-game could (and probably is) simply a mistake made by whoever modeled the weapon. As for the select-fire capability, once again, either a mistake or the devs decided to add it for gameplay reasons and didn't care that it doesn't make sense, which would be feasible considering how little sense the game makes overall.
IMI Uzi(**)
The IMI Uzi appears as the "Uzi" (one of the few guns to be called by its actual name in-game) and is unlocked for purchase by buying the "Hotline Miami" DLC. It holds 30 rounds in a 32-round magazine.
Sterling L2A3(**)
The Sterling L2A3 appears as the "Patchett L2A1" and is unlocked for purchase by buying the "Gage Historical Pack" DLC. It also holds an incorrect 20 bullets in the standard 34-round magazine. The name "Patchett" refers to the weapon's designer, George William Patchett, and the name of the weapon in its early development.
]
Cobray M11/9(**)
The Cobray M11/9 appears as "Jacket's Piece" and is unlocked for purchase by buying the Jacket Character Pack. It holds a correct 32 rounds and has a after-market vertical foregrip in place of the barrel nut.
Modified Version
KRISS Vector(**)
The KRISS Vector was added with the Gage Ninja Pack DLC. It's called "Kross Vertex" in-game. It can be modified with a long barrel to make it resemble the Vector CRB, which is the civilian semi-auto only variant. The weapon also has its own unique suppressor. The weapon holds 30 rounds in the "25+"-round magazines.
IMI Micro Uzi(**)
The IMI Micro Uzi appears as the "Micro Uzi" and is unlocked for purchase by buying the "Yakuza Character Pack".
TsNIITochMash SR-2M Veresk
The SR-2M Veresk was added along with the Jimmy character from the free Hardcore Henry Packs DLC, with his voice and likeness given by Sharlto Copley from the movie Hardcore Henry. The weapon is called "Heather" ingame, which is the English translation of "Veresk". It's notably the first subgun that can be dual-wielded. It has a slightly incorrect magazine capacity of 32 rounds instead of the real-world 30, likely because the stats, sans the rate of fire and stability, are a copy-and-paste of the Cobray M11/9 (Jacket's Piece).
Akimbo
Heckler & Koch UMP45(**)
The Heckler & Koch UMP45 was originally an NPC-exclusive weapon, being used by enemy factions such as the GenSec Elite SWAT and the Murkywater PMC enemies. It was eventually added as a player-usable weapon with the "John Wick Weapon Pack" alongside the P30L and Desert Tech SRS-A1. Named the "Jackal SMG", it is otherwise known in-universe as the "Schäfer & Gewehr AMP", made by the same company that created the Bootleg, Gewehr 3, and Contractor pistol.
Despite being ostensibly based on the .45 ACP model, the weapon's statistics and performance in the game are more akin to the UMP-40 variant, most notably the fire rate and 30-rounder magazine.
Carbines / Assault Rifles / Battle Rifles
The OA K23B and AKMSU count as SMG's in-game, but are actually carbines, therefor their entries will appear here.
Colt Model 733
The Colt Model 733, fitted with an A2-style receiver and 6-position stock, appears as the AMCAR, the very first primary weapon. Originally, its damage output was outright miserable compared to every other long arm and little could be done to fix it. Dumped as soon as possible, but kept by few as a voluntary handicap. After the big 2015 Crimefest weapon balance update, it now has higher damage output, on par with the G36K (JP36), which has a bit lower than average damage for an assault rifle in the game. Given the influence of Heat on the production, the highly specific choice of model probably isn't a coincidence.
Izhmash AKS-74
The Izhmash AKS-74 is the second primary weapon unlocked, at reputation level 1. It's simply called AK Rifle and holds 30 rounds. It can become a regular AK-74 if the "Classic Stock" from The Butcher's AK/CAR Mod Pack is equipped.
Colt M4A1
The Colt M4A1 appears as the "CAR-4" and is unlocked at reputation level 4. Essentially it is an upgrade of the starting Model 733 and features tan flip-up iron sights, KAC-style free-float railed foregrip, and a railed low-profile gasblock. It is frequently used by law enforcers and holds 30 rounds. The NPC-exclusive model for this weapon features some small differences from player-used ones, such as a laser unit mounted on top of the railed handguard, instead of the side like on the player available M4A1. This rifle was used by the Police Snipers, were it was claimed that it was a "higher caliber variant" of the M4 (possibly something like .458 SOCOM or .50 Beowulf) It was replaced however with a PSG-1 mockup.
The M4A1 has a ridiculous amount of modifications available (albeit most of them are locked behind DLC) which means it can be modified to fit many different roles. These modifications, if put together correctly, can make the M4A1 resemble a whole host of different real world AR variants.
Steyr AUG A2
The Steyr AUG A2 is at reputation level 8 and is named the "UAR" (presumably short for Universal Army Rifle, the English translation of Armee Universal Gewehr, or AUG). It holds 30 rounds and is rather accurate and powerful. It can be fitted with a railed fore end to make it resemble an AUG A3, but the rifle still lacks the bolt release of an A3. Oddly, instead of its build-in folding foregrip it has a section of rail added to the hinge and an aftermarket vertical grip attached to said rail.
Upon launch, the rifle can be seen using a Magpul PMAG, which suggests it was not based entirely on an authentic AUG. After the animation update, however, it gains the AUG's proprietary magazine.
As of update 61, the Raptor polymer body was added as a mod for the weapon, this mod will give the weapon the appearance of the Thales F90.
Izhmash AKMS
The Izhmash AKMS appears as the AK.762 and is unlocked at reputation level 16.It holds 30 rounds and has less total ammunition than the AKS-74. A golden version of this weapon with diamond plating on the wooden handguard was released as a community reward, though is more expensive and has a lower concealment stat with no other differences. It can become a AKM if the "Classic Stock" from The Butcher's AK/CAR Mod Pack is equipped.
Heckler & Koch G36KV
The Heckler & Koch G36KV makes an appearance as the "JP36", unlocked as early as level 16. The damage output stays mediocre no matter what, but its main draws are easy recoil, solid accuracy, and a deep 240 round ammo pool.
Heckler & Koch G36C
Installing the "Compact Foregrip" turns the gun into a convincing G36C.
Olympic Arms K23
The Para SMG is unlocked at reputation level 19. A very competent and modifiable gun, it can easily cover whatever a gimmick primary weapon might lack - like a pocket CAR-4, albeit with worse concealability potential. It is a confusing mix of half-dozen different ultra-short AR-15 pistols and carbines, but since the game assets label it as "olympia", that's the headline.
Olympic Arms K23B
The basic look of the gun is closest to the OA K23B ultrashort carbine. However, the removable carry handle and RIS are featured only in its sister OA K23B Tactical, the emergency wire stock is taken from an M231 FPW and the original aluminium foregrip has been extended over the gas block to make it a dead ringer with a round-front type La France M16K. The name itself may be a dim reference to the fact that most of the involved guns have 9x19mm variants as well, but that's reaching.
Attaching a Milspec Magazine and a Standard Stock bring the Olympic Arms K23B closest to its retail shape.
Olympic Arms K23P
Buying a Bare Essentials Stock for extra concealment removes the wire stock and leaves only the buffer tube behind. This combined with the old A2 flash hider out it as the Olympic Arms K23P, a semiauto pistol version of the same caliber.
M4 CQBR / Mk 18 Mod 0
Attaching a Medium Barrel for extra accuracy and replacing the basic handguard with something else makes the Para finally look like an actual assault rifle. However, the barrel's rather specific ~10" length (falls just short of the 11.5" AMCAR) makes the most American option the Mk. 18 Mod 0, ignoring the lack of a gas block/front sight and the too short foregrip.
Springfield Armory M14
A Springfield Armory M14 with a McMillan M2A stock and a short 16" barrel appears as the "M308" as in the first Payday. It is set to semi-auto by default but can be switched to full-auto and holds 10 rounds in a 20-round magazine. Prior to the first Gage Weapon Pack release, it was semi-automatic only, making it the only assault rifle to have the mode; as of then, it is now the only weapon with multiple fire modes that defaults to semi-auto. The weapon can be modified with a JAE 100 G3 stock or a SAGE EBR Chassis, the later makes it resemble a Mk 14 Mod 0 EBR.
Izhmash AKMSU
A variant on the Izhmash AKMSU is unlocked at reputation level 29 and is named the "Krinkov," the nickname of the AKS-74U. It holds 30 rounds and is a secondary weapon, rather than a primary like the other three Kalashnikov rifles.
Akimbo
Bofors Ak 5
The whole Bofors Ak 5 family appears as the "AK5", all packed inside one gun's upgrade selection. Its accuracy and recoil are solid from the start, but the low damage needs help to reach its best. Unlocked at level 33.
Ak 5B
Sticking on the "Bertil Stock" from the designated marksman model turns the AK5 into an ersatz Bofors Ak 5B.
Ak 5C
The modernized Bofors Ak 5C comes together by replacing almost everything that comes off the receiver.
FN FNC
The "Belgian Heat" handguard is cribbed straight off the FN Herstal FNC in a direct reference to Lt. Vincent Hanna (Al Pacino) from the movie Heat.
Colt M16A4
The Colt M16A4 with a short barrel appears as the "AMR-16" and is unlocked at reputation level 39. It is shown with a safe/semi/auto selective fire capability, meaning it was based on the export International Model R0901, and incorrectly holds 30 rounds in a 20-round magazine. It can be equipped with an M16A1 handguard with the Blast From The Past modification. Unlike the other AR-15 type rifles, the M16's gas block and front sight disappear when using optics.
SIG SG 552-2(**)
The SIG SG 552-2 appears as the "Commando 553" (referring to the SG553 instead) and is available to purchase by anyone who owns the Armored Transport DLC. It Holds 30 rounds. The rifle can be confirmed as a 552-2 by the permanent scope rail, the simple, folding front and rear iron sights instead of the original sights of the SIG assault rifle series, and the proprietary SG 552 exclusive bolt handle. As of the First Person Animations Update, the weapon's magazine is translucent and visibly empties when firing, rather than being solid brown
FN SCAR-H(**)
The FN SCAR-H appears as the "Eagle Heavy Rifle" and is available to purchase for owners of the Gage Weapon Pack #1 DLC. It holds 20 rounds and is a powerful weapon. A version with a FN SSR stock is used by some Murkywater PMC enemies.
Modified Version
FN FAL(**)
The FN FAL appears as the "Falcon Rifle" and is available to purchase for owners of the Big Bank DLC. It holds 20 rounds and is a very flexible weapon. Notably, the FAL was the first weapon to have its accessories linked to DLC achievements rather than random drops. It notably has a DSA railed upper-receiver.
DSA SA58 OSW
The FAL can become a DSA SA58 OSW with the "CQB Foregrip", "Tactical Grip", and "CQB Stock" modifications.
IMI Romat
Attaching the "Retro Foregrip" and "Wooden Stock" to the FAL allows it to impersonate the IMI Romat (although the FAL rear sight, DSA upper-receiver, and barrel remain the same).
FAMAS F1(**)
The FAMAS F1 appears as the "Clarion Rifle" and is unlocked for purchase by buying the "Gage Assault Pack" DLC. It incorrectly holds 30 rounds in a 25-round magazine.
IMI Galil ARM 7.62(**)
The 7.62mm variants of IMI Galil ARM appears as the "Gecko 7.62" rifle and is available to purchase for owners of the "Gage Assault Pack" DLC. It incorrectly holds 30 rounds in the 25-round magazine and has a much higher RoF than actual ARMs.
Heckler & Koch G3A3(**)
The Heckler & Koch G3A3 with a Heckler & Koch HK21 machine gun's stock appears as the "Gewehr 3 Rifle" and is available to purchase for owners of the "Gage Assault Pack" DLC. It holds 20 rounds in the magazine.
Enfield L85A2(**)
The Enfield L85A2 was added alongside the Clover Character Pack as the "Queen's Wrath". By default it holds 30 rounds and has a Grippod vertical grip.
HS Produkt VHS-D2(**)
The HS Produkt VHS-D2 was released as part of the "Dragan Character Pack" DLC, much like the L85A2 was part of Clover's DLC. It is known in-game as the "Lion's Roar", has a high rate of fire and overall good stats, though it has a long reload time and if unmodified, high recoil.
TsNIITochMash AS Val(**)
The AS Val was added with the Sokol Character Pack. It's called "Valkyria" in-game.
Kel-Tec SUB-2000(**)
Introduced in the Golden Grin update as a farewell gift from the Dentist, the Kel-Tec SUB-2000 appears as the "Cavity 9mm". A unique weapon to put it in gentle terms, it is a pistol caliber carbine primary weapon that achieves the damage level of a light sniper rifle using 9x19mm rounds. It fires exclusively in semi-auto as it does in real life and correctly holds 33-rounds in the extended Glock magazine with a +2 base-plate it uses. For some reason it is modeled without the red plastic blade in the front sight.
SUB-2000 Gen 2
Slapping on the "Appalachian Foregrip" transforms the first-run gun into a current Gen 2 model.
Heckler & Koch HK416C(**)
The Heckler & Koch HK416C was added with the Sydney character pack. It actually goes by two names in-universe. The rifle is called SG416C but Sydney renamed it "Bootleg Rifle" after apparently buying from a blackmarket arms trader behind a gas station in Australia. Sydney also has a tattoo of the carbine on her left arm. It is permanently fitted with a 100-round Beta C-Mag and a Magpul RVG vertical foregrip.
CZ 805 BREN A1(**)
The CZ 805 BREN A1 was added with the Biker Heist Packs and called the "CR 805B" in-game. It's strangely categorized as an SMG and is therefor a secondary weapon. It's fitted with a non-removable Magpul MVG foregrip. It has a factory gray and black two-tone finish and is fitted with a STANAG magwell (which can also be a factory option). It can be given a shorter barrel that turns the rifle into an A2 model.
Shotguns
Remington Model 870 Field Gun
A Remington Model 870 Field Gun, called the "Reinfeld 880" is unlocked at level 8, it has synthetic furniture instead of wood and has a pistol gripped stock. It's the first unlockable shotgun. It holds 6 shells and is used by law enforcers, Hotline Miami mobsters, Russian mercs, and the basic green Bulldozer.
Remington Model 870 Short-Barreled
A stubby variant of the Remington Model 870 Field Gun is unlocked at level 13 and is called the "Locomotive 12G". It holds 6 shells in what appears to be a 3-round tube and was the only secondary shotgun prior to DLC and patches. It is overall similar to its full-sized counterpart, but has slightly higher damage and a higher rate of fire but shorter range and lower accuracy.
Izhmash Saiga-12K
The Izhmash Saiga-12K (going by the name "IZHMA 12G") is one of two select-fire shotguns in-game, along with the AA-12. It holds 7 shells in a box magazine and is unlocked at level 26.
The model is not an actual Saiga-12K, but is rather a hybrid taking several components from the AKMS. Firstly it features a standard ribbed AKM top cover, rather than the smooth cover used on the Saiga-12 which has a larger ejection port with a sprung sliding cover over the rear portion. Secondly it has an under-folding AKMS stock which was not available on the Saiga-12. Lastly the receiver is a hybrid of an AKMS one and a Saiga, with the magazine release being immediately ahead of the trigger guard and receiver dimples above the magazine, but with a Saiga-style front trunion (lacking the corresponding rivets however).
Double Barreled Shotgun
A Double Barreled Shotgun appears as the "Mosconi 12G" and is unlocked at level 39. Obviously it only holds two shells but is one of the most powerful weapons in the game.
Franchi SPAS-12(*)
The Franchi SPAS-12 was added during Crimefest 2014 and is called the "Predator 12G". It fires in semi-auto and holds 6 rounds in the default short tube, the "Extended Magazine" gives it the more standard length tube but it holds 10 rounds instead of the correct 8. It can be bought regardless of level and is unlocked by being a member of the Payday 2 Steam group.
Beretta S3/CZ Redhead Deluxe Hybrid(*)
This Over and Under Shotgun was introduced along with the Bonnie Character update. It appears to be a hybrid of the Beretta S3 O/U and CZ Redhead Deluxe O/U. Named the "Joceline O/U 12G" in-game.
Benelli M4 Super 90(**)
The Benelli M4 Super 90 appears as the "M1014" in-game, the US Military designation of the shotgun. It first appeared in the Death Wish Update in the hands of the GenSec Elite shotgun units, albeit in the M4 tactical configuration. A player-usable version was finally added in the "Gage Shotgun Pack" DLC. It holds 8 shells in the 7 round tube.
Kel-tec KSG(**)
The Kel-Tec KSG, called the "Raven" in-game. As in most games, there is no tube switching or selection shown and the shotgun's magazine is treated as a single tube. Notably it is one of the most concealable shotguns in the game and has the highest capacity of any of them. Holds 14 shells and was added in the "Gage Shotgun Pack" DLC.
Sentinel Arms Striker-12(**)
The humble fixed-drum Striker-12 appears by the family's most prestigious name; the Street Sweeper. In Overkill's usual fashion, it's a mix of all of the different versions mooshed together in a highly educated, equal measure. Unlocked at level 33, it's very capable of terminating an entire room of FBI SWAT in one 12-shot sweep, but the low damage needs specialization help to cope with Maximum Response teams. It was the only secondary-class shotgun introduced by Gage's Shotgun Pack.
MPS AA-12 CQB(**)
The MPS AA-12 CQB was added with the "Butcher's BBQ pack". It can be identified as the CQB model due to its short barrel. In-game it's know as "Steakout 12G", possibly a pun on the Ithaca 37 "Stakeout" model (ironically, a standard Ithaca 37 was added later with the "Goat Simulator" DLC)
It's possible to flick between semi and automatic fire in-game, something not possible on real AA-12s. They are full-auto only.
Ithaca 37(**)
Along with the "Goat Simulator" DLC (where do they get these ideas?) a full-size Ithaca 37 was added, oddly as a secondary weapon. Called "GSPS 12G" in-game. It incorrectly holds 7 rounds in the standard 4-round tube magazine.
Winchester Model 1887(**)
The Winchester Model 1887 was added with the Biker Character Packs and is called the "Breaker 12G" in-game. It incorrectly holds 7 rounds in its 5-round tube magazine. Though Model 1887s can actually hold 5+2 by placing one shell directly into the chamber then placing a second shell on the loading ramp in the receiver, this action is not done when reloading the in-game Model 1887, the player characters simply loading all seven shells into the tube magazine.
Crye Precision SIX12
The Crye Precision SIX12 was added during "Hoxton's Housewarming Party" as a secondary shotgun. It's called "Goliath 12G" in-game and is based on the 2nd prototype.
Modifications include a short barrel for extra compactness and a custom-made quick-detach silencer, a strange addition since the SIX12 does have a proprietary suppressor system in reality that consists of a SilencerCo Salvo-12 and a dedicated foregrip sleeve. Curiously, the already-in-game Salvo-12 is available as an option for a suppressor, albeit as an ordinary muzzle extension instead of the specialized barrel group it belongs to.
Machine Guns
The first three machine guns (The RPK, M249 Para and HK21E) were added in the seconed "Gage weapon pack" DLC. The "Gage Historical Pack" introduced the MG-42 and the "Crimefest 2015" update introduced the Ksp 58. The weapons can only be hip-fired and are very inaccurate. The bipods could initially not be used but during the very same Crimefest event that introduced the Ksp 58, a new attachemnt called the "Lion bipod" was added to all MGs, allowing the player to deploy them and fire more accurately and with almost no recoil. One cannot move when the bipod is deployed however.
While they are all categorized as LMG's in game, the MG42 and FN M240 are actually GPMG (General Purpose Machine Guns)
Izhmash RPK(**)
The RPK appears as the "RPK" and is immediately unlocked at the start, on reputation level 0. It incorrectly holds 100 rounds in a 75-round drum magazine. The weapon comes lightly modified with a pair of small Picatinny rails on each side on the front portion of the barrel, an elongated birdcage-style flash hider, and a Romanian AIMS rifle handguard featuring a vertical grip.
FN M249 Para(**)
The M249 Para appears as the "KSP" and is unlocked at reputation level 45. It has a 200-round detachable ammo drum. It is also the weapon of choice for the Skulldozer special enemy and the Commissar, the target of the Hotline Miami DLC heist.
Heckler & Koch HK21E(**)
Returning from the previous installment, the Heckler & Koch HK21E appears as the "Brenner 21" and is unlocked at reputation level 75. It has a 150-round detachable belt box magazine. It has a MP5-style rear-sight rather than the 21E's real rear sight. It has a front grip that's tilted to the left in order to making it easier to hold.
MG 42(**)
The MG 42 appears as the "Buzzsaw 42" and is unlocked for purchase by buying the "Gage Historical Pack" DLC. It incorrectly holds 150 rounds in a 50-round drum magazine and has the highest rate of fire of the LMGs.
Modified Version.
FN M240
Although it's called "Ksp 58" in-game, after the Swedish version of the FN MAG 58 and even has the distinctive Swedish green lacquer finish, it is actually modeled after the M240, denoted by the short flash-hider, carry handle design, sights, the railed feed tray cover of the B model, and the stock design (both the default wood stock and the plastic stock use the same model). It was added on day 5 of "Crimefest 2015" and along with it the ability to use a bipod with Machine Guns.
Sniper Rifles
The 'Gage Sniper Pack' downloadable content introduced 3 new weapons to the players' arsenal. All 3 weapons (the Remington MSR, Blaser R93 LRS2, and Barrett M95) are slow-firing but powerful bolt action sniper rifles, featuring 2 unique scopes and a 45-degree offset iron sight attachment. All 3 are capable of firing through certain objects, such as thin walls or police riot shields. This also applies to the Mosin-Nagant and Winchester Model 1873, which were released later. Along with the Point Break heists update, the character Bodhi and a Winchester Model 70 was added for free to anyone who downloaded the update.
Remington MSR (**)
The Remington MSR appears as the "Rattlesnake" and is unlocked at level 15. It holds 10 rounds in the magazine.
The Barrett M95 appears as the "Thanatos" and is unlocked at level 65. It uses a 5 round magazine. Notably, it was the strongest weapon in the entire game upon its release, and the second most powerful one so far, having an astounding damage stat of 2900, second only to the RPG-7 included with the OVERKILL Pack, which deals a solid 10000 damage per shot.
Mosin Nagant M1907 Carbine (**)
The Mosin Nagant M1907 Carbine is seen as the "Mosin-Nagant" and is part of the Gage Historical Pack DLC. Unlike the first three sniper rifles of the game, it can use ironsights, a trait shared with the Winchester 1873 and Model 70.
Winchester Model 1873 (**)
The Winchester Model 1873 appears in the game as the "Repeater 1874" and is part of the "Butchers Western Pack" DLC. Oddly enough, despite being chambered entirely for pistol-grade ammunition types, it is classified as a sniper rifle, and thus can penetrate thin walls and shields. Like the Mosin-Nagant, the iron sights are usable, unlike the Nagant however, the irons are the basic sights with the scope being a modification.
Walther WA 2000 (**)
The Walther WA 2000 Generation 1 was added with the "Gage Ninja Pack" DLC. It's called "Lebensauger .308" in game, which can roughly be translated from German to "life-sucker". While the .308 in the name would suggest the weapon is chambered in .308 Winchester, it is more likely to be based on a 7.62x51mm NATO Gen 1 rifle. The magazine in game holds 10 rounds even though it's modeled after the standard 6-round magazine.
The Desert Tactical Arms Stealth Recon Scout A1 Covert was added with the release of the "John Wick Weapon Pack". Along with the aforementioned Heckler & Koch P30L/Contractor, the SRS-A1 was ostensibly modeled to ape the rifle used by Wick in his movie, though the final weapon cannot be modified to resemble the source material. Named the "Desertfox Sniper Rifle", it has a black and tan two-tone finish.
Launchers
M79 Grenade Launcher (**)
The M79 was added in the Gage Assault pack DLC. It's called the GL40 in-game, same as the first Payday. It is possible to hurt or kill one's own team members with it, so it pays to be careful when using it. Additionally, the grenades have no arming distance. This can be dangerous to the player as the grenade can be shot and detonated the split-second it's fired, leading to the user getting hurt.
All the grenade launchers deal the same damage, 340.
Milkor MGL Mk 1L (**)
The Butcher's BBQ Pack added a Milkor MGL Mk 1L to the game, called Piglet in-game. Unlike the other grenade launchers, the Mk 1 can be modified with sights, gadgets and more then one different stock.
RPG-7 (**)
The RPG-7 was added in the Overkill Pack. It has the highest damage of any weapon in the game at an astounding 10000, but the player can only carry 4 rockets in total and ammo pickups are disabled, meaning more rockets can only be obtained from ammo bags. The weapon can easily incapacitate the user and their whole team if fired recklessly and rockets can be detonated mid-flight if it's hit by enemy fire, something that happens a lot on more intense heists.
Modified Version.
China Lake Launcher (**)
The China Lake Launcher, known as the "China Puff" in game, was added in the Wolf Pack (the pack is free for anyone who bought the DLC back in the first Payday). Like the RPG, it's a secondary weapon.
Explosives
C4
C4 could originally only be used with the right Technician skills. As of Update 100 however, any player can use C4 by equipping Laser Tripmines, which come with a separate set of C4 charges. Laser Tripmines are powerful explosives that detonate when an enemy crosses the laser beam, or they can be toggled to merely act as a sensor device and mark special enemies or security guards that pass by, along with an audio cue. C4 charges are kept separate from Tripmines (in contrast to pre-Update 100, where a single charge used up a Tripmine) and are used to open doors and safes quickly. Some heists (such as The Bomb heists, Hotline Miami, and more) have a bag of C4 charges in the map to use for scripted objectives, these are treated as mission items rather that deployable equipment.
M18 Smoke Grenade
The M18 smoke grenade is used by law enforcers both as an actual smoke grenade but also as a flash bang, the model being reused for the latter.
M67 Hand Grenade (**)
The M67 hand grenade was added in the first "Gage Weapon Pack" DLC. Players who own the DLC will start a heist with three grenades and they can also buy a briefcase that holds three grenades that all players can pick up and use. One should be careful when throwing one however, as police gunfire can detonate the grenade if it's hit.
Update 100 added another version of the grenade called the "HEF Grenade" that can be used by any player following the Steam group for Payday 2. They work exactly the same as the Aforementioned ones.
Model 24 Stielhandgranate (**)
The Model 24 Stielhandgranate was added as a melee weapon in the "Gage Historical Pack". It's referred to as the "Potato Masher" in-game.
M84 Stun Grenade
The M84 Stun Grenade was added in the "Hoxton's Housewarming Party" update as the "Concussion Grenade".
Other
Hand Held M134 Minigun
A Hand Held M134 Minigun was added in the Overkill Pack DLC, and has the highest rate-of-fire of any weapon. It holds a total of 750 rounds, and has to be refilled via ammo bag deployables. Like LMGs, there is no actual iron sighting and the usually-nominal zoom is even less reliable. As usual in video games and films, the weapon appears to have no power source.
Modified Version.
Sentry Gun
The Heckler & Koch MP5K appears as part of the Technician's Sentry Gun deployable, seen inside a case. As in the first game, the Sentry Gun can be destroyed by enemies and will shut down when its ammunition supply is exhausted. Aside from the Sentry, the MP5K can be used by modifying the MP5, as seen above. In Update 100, this model was replaced with a new Sentry Gun using a FN P90 as its base.
Browning M2HB
A Browning M2HB machine gun is the main armament of the SWAT van turret weapons system. It is incorrectly depicted firing at almost twice its actual rate of fire at exactly 1000rpm, 600rpm is the max fire rate of a real Browning M2, and (thankfully for gameplay purposes) it does pitifully low damage for a .50 cal machine gun. It does however shred armor very quickly on higher difficulties. Though the rate of fire is befitting of the Browning M3 Aircraft, it is obviously modeled after an M2 and not the M3. The SWAT Van Turret itself appears to be a modified version of a C.R.O.W.S II RWS. The Browning M2HB is a very commonly used weapon for this kind of weapon system.
Heckler & Koch HK416D
In the opening live-action title sequence, Chains wields an airsoft Heckler & Koch HK416D rifle.
