The AMCAR performs to a moderate capacity, although it is inferior to most other assault rifles. Its limited selection of modifications limits its flexibility, but it has the highest base stability of all the assault rifles (though coupled with the lowest accuracy) and moderate damage that can easily be modded to 40 damage.
The weapon has three primary drawbacks:
Low magazine size
Accuracy is among the lowest of the rifles.
It has a limited selection of modifications.
The AMCAR's lackluster capabilities make it a somewhat difficult weapon to use. The AK and CAR-4, which new players will quickly unlock, are direct upgrades in almost every way. The AK is capable of killing the lightest SWAT units with a single headshot while unmodified, costs the same amount as the AMCAR, and is available for unlock at a reputation level of 1. All of this makes the AMCAR a poor weapon choice once other rifles are available.
An unmodded AMCAR will be added to the player's inventory upon them going Infamous without owning a level 0 primary weapon.
While a fairly usable gun for starting players, it is recommended to get a new primary weapon as soon as possible, as outside of relatively close and easy combat, the AMCAR fares horribly when faced with multiple advanced enemy personnel coming on the player's position on higher difficulties.
Using mods can remedy the AMCAR's bad performance somewhat. Since the rifle's Concealment and Stability is quite high by default, it is better to focus on enhancing its meager amount of Damage and Accuracy for improved control and stopping power. Although, even with making use of the Gage Mod Courier DLC parts, it is still utterly inferior to every other rifle that comes after it.
One of the few advantages of the AMCAR is its high ammunition cap. A mastermind with Control Freak can make use of it as a cheap method of keeping civilians down for an extended amount of time because of its 220-round ammunition capacity and reasonable concealment stat, assuming they cannot still afford a JP36, which is better in every regard, even without any modifications.
If the player's budget allows it, or if one is reclimbing the ranks after going Infamous, the Eagle Heavy, Commando 553, Predator 12G (however, on the PC it is ironically the other way around), and RPK are all better reputation 0 alternatives to the AMCAR. In addition, most of the Akimbo weapons are better options than the AMCAR if modded to compensate for their reduced stability.
Although the main flashlight has a toggle switch, the laser sight component of the LED Combo is pressure-activated, meaning the laser will stay on as long as the pressure switch is depressed. This switch is not placed where it should be, however (on foregrips, magazine wells, etc...) and is instead ziptied to the main taclight, leaving no plausible mean for the user to toggle it without awkwardly moving their off hand off the weapon and gripping the attachment itself.
Requires a pre-installed sight mod to mount. The magnification level can be changed while aiming down the sights, and the aiming FOV will automatically adjust itself. Not compatible with the Acough Optic, Military Red Dot, Milspec Scope, Combat Sight, Reconnaissance Sight, Theia Magnified Scope, Box Buddy Sight, the JP36's Original Sight, the Raven's Flip-up Sight or the GROM and Platypus 70's iron sights. Currently bugged and not appearing as intended on certain weapons, for a list see here. They're still listed below even if broken.
The Milspec Mag was based on the NATO STANAG 30-round magazine. Despite this, none of the weapons capable of using it can achieve this capacity when it is equipped. Those that come with the modification pre-installed such as the AK5 and Queen's Wrath house the correct amount of bullets, however.
Stats-wise, the L5 Magazine is identical to the Expert Mag, so the only reason to choose the L5 over the Expert Mag would either be the relative ease of the former's acquisition, or down to aesthetics if both magazines are available to the player.
Due to it supporting a wide array of weapons, the Speed Pull Magazine is the first single modification to have multiple different icons.
The Speed Pull Magazine equips the AMCAR, Para, and AMR-16 with the Milspec Mag., but despite this they neither get increased magazine capacity nor reduced concealability, however it equips the Mark 10 with its Extended Mag and does give it increased magazine size, but does not increase stability nor does it decrease its concealment. Additionally, equipping the Speed Pull Magazine on the AK.762, Golden AK.762, and Krinkov will give them the AK's 5.45mm Bakelite magazine, despite the mismatched caliber.
Upon release, the default reticle of this sight was a chevron instead of the retail version's red dot. After the release of the Gage Mod Courier DLC, it was reverted to the regular sight's red dot.
It is functionally the same as the standard Military Red Dot Sight, but the sight's casing is tan instead of black with the line "A-10" scrawled on near the adjustment knob. The sticker on the lens cap's interior also says "I <3 Payday" instead of having a picture of an American flag.
This sight was based on the Aimpoint CompM2 optic. While it is portrayed as a high-zoom scope in-game, the CompM2 is actually a reflex sight, meaning it offers no magnification in reality.
Visually speaking, the War-Torn Stock is just a Wide Stock with a few miscellaneous items bound to it by a black cable tie.
Judging by the name and its ramshackled appearance, the War-Torn Stock is likely a broken product through repeated use that was salvaged with spare parts, thus would justify its inability to keep the weapon steady during fire.
The text on the handguard of the DEVA (AMCAR RIFLE | Deva [✓]) is katakana for "deva" (デバ deba, due to the lack of "v" sounds in Japanese). The original skin submission had its name written regularly instead of in all caps.
The Aztec is an ancient civilization that dominated most of Mesoamerica from the 14th to the 16th century.
It is based on the Colt 727 carbine, a "miniaturized" variant of the Colt M16A2, as evident by its integral A2-style brass deflector, carry handle and rear sight. Apparently, it was supposed to be modeled after a Colt M733 in reference to the movie Heat.
The Colt 733 in fact has an A2-style upper receiver, complete with carry handle and sights, though its brass deflector is modeled somewhat differently from that of the in-game weapon.
When a sight mod is mounted on the AMCAR, the carrying handle disappears and a picatinny rail appears in its place.
This is actually impossible to do as the carrying handle on the Colt 733/727 is built into the weapon's receiver and cannot be removed. What would have been an accurate representation is that a rail mount is attached on top of the carrying handle, instead of it being removed.
Another possibility is that the AMCAR was based on both the Colt 733/727 and the Colt 933, as the Colt 933 has a flat-top receiver, removable carry handle and MIL-STD-1913 Picatinny rail system as seen on the AMCAR when a sight is placed on it.
The AMCAR is one the only two AR-15-pattern rifles in the game to retain its gas block when an optic is attached. The other weapon is the CAR-4. Regardless, the AMCAR's gas block is the only one to remain ever-present after the application of mods onto the weapon, said part on other weapons of its kind is often removed with a sight or handguard mod attached.
It is one of two weapons whose name derives from the AMCAR-4, the other being the CAR-4. Unlike its namesake, however, the AMCAR performs very poorly, being vastly inferior compared to other assault rifles; what versatility and good handling of the old weapon seemed to have been given to the CAR-4 instead.
The AMCAR's old inventory icon had a much longer barrel than the in-game weapon, suggesting that it was originally supposed to support an extended barrel mod before it was scrapped during production. As of CrimeFest 2015, however, the carbine received a new store icon with a shortened barrel reflective of the part's actual length in-game.
As it shares the lower receiver model with the AMR-16, the CAR-4 and the Para, the model name AR-15 can be seen stamped onto the side of the AMCAR.
During the beta, it could only accept a magazine mod.
Up until the first update of Crimfest 2015, its inventory icon and The Guide of Bain's guns section showed it with the Milspec Mag. instead of its default Vintage Mag.
The AMCAR and the CAR-4 are the only AR-15-type guns in PAYDAY 2 where the bolt release is used to chamber a new round after the gun is empty, instead of the charging handle.
