NOTE: This article is about M4A1 carbine in ArmA 2. For the M4 Scorcher self-propelled gun artillery vehicle in ArmA 3, see M4 Scorcher.


« The M4A1 Carbine is a shortened version of M16. It sports a shortened barrel and collapsible stock, making it the Special Operations weapon of choice. In contrast to the M16A2, with its 3-round burst mode, the M4A1 is capable of fully automatic fire.

Thanks to the SOPMOD program the M4A1 can be modified with a variety of special accessories including optics such as the M68 Aimpoint and ACOG, an easily detachable suppressor, the M203 under barrel grenade launcher, and many others.

The M4A1 is a 5.56 mm carbine used by the U.S. Marines in ArmA 2.

Overview Edit

The M4A1 is a gas operated, selective-fire carbine that is chambered to fire the 5.56×45 mm NATO round.

It can load from the same 30 round STANAG magazines used by other 5.56 mm weapons like its rifle counterpart, and is able to attain a fire rate of up to 667 rounds per minute, with a muzzle velocity of 930 m/s. The M4A1 has several variants fitted with close range optical sights such as the CCO red dot sight, as well as HWS holographic sights. In addition, there are also (albeit non-functional and purely cosmetic) laser pointers and flashlights. Some variants are also fitted with sound suppressors by default.

Arma 2 M4A1

A USMC Corpsman (left) and Force Recon operator (right) armed with M4A1 in ArmA 2. Note that the Force Recon M4A1 is camouflaged.

Primarily wielded by both USMC vehicle crews, U.S. Navy Corpsmen, and Force Recon special forces units during the events of Operation Harvest Red, the M4A1 is a shorter barrelled variant of the M16A4 and the M16A2 rifles. Because of its shorter length, it is far better for use in urban combat than the M16A4 as the M16A4's long barrel makes it difficult to exit vehicles and to manoeuvre inside buildings properly.

Like the M16A4, the M4A1 is designed with modularity in mind and features a wide variety of accessories for the operator to choose from. Both ironsights and non-magnified optics give the M4A1 an effective range of up to 300 metres.

Because of its carbine configuration however, the M4A1 is still less accurate than its rifle counterpart at almost every distance. As a result, it should not be used for any engagements that exceed 400 metres (even with the ACOG-equipped variants).

In addition, suppressed variants of the M4A1 such as the M4A1 CCO SD, are restricted to using subsonic 5.56 mm ammunition and cannot utilise non-subsonic 5.56 mm magazines.

Camouflage Edit

  • Black: Standard matte black and dark grey paint finish used on regular USMC M4A1s.
  • Woodland: Woodland spraypaint camouflage finish. Used on M4A1s carried by USMC Force Recon operators.
  • Desert: Three-colour desert spraypaint camouflage finish. Only used on M4A3s.

The M4A1 M203 is a modified variant of the baseline M4A1 carbine that has an underbarrel grenade launcher attached to it. As with its parent counterpart, it is chambered to fire the same 5.56 mm NATO round while the underbarrel M203 launches 40 mm grenades instead.

The M203 has a conventional leaf sight that is accurate at ranges of up to 300 metres. In every other aspect, it is identical to the M4A1.

The M4A3 is a separate variant of the standard M4A1 carbine used exclusively by ACR special forces. It was added with the release of the Operation Arrowhead expansion pack.

While stated to be a different weapon, the M4A3 is actually functionally identical to the baseline M4A1 in virtually every way, save for using a desert finish, the flashlight accessory being usable, and is always equipped with a CCO red dot sight.

However, it does have one unique attribute in that it is able to utilise magazines with subsonic 5.56 mm ammunition (whereas the M4A1 is incapable of doing so).

It also has a foregrip attached just like USMC Force Recon M4A1s, though it is merely cosmetic and does not affect its handling in any way. It does not have any variants that can be fitted with muzzle suppressors.

The M4A3 M203 is the grenadier variant of the M4A3 carbine that is used exclusively by ACR special forces. It was added with the release of the Operation Arrowhead expansion pack.

Just like the M4A1 M203, it is functionally identical in every aspect aside from using a desert camouflage finish and having a functional laser pointer instead. The M4A3 M203 is always equipped with an ACOG riflescope.

Along with the baseline M4A3, it does not have any variants that can be fitted with a muzzle suppressor.

Trivia Edit

  • This M4A1 is currently used in over 41 different countries. It is visually similar to earlier carbine modifications of the M16 such as Colt's "CAR-15", and was designated as the "XM177" in real-life service.
  • Both the M4A1 and its long barrel rifle counterpart are are implied to have been completely replaced in U.S. military service by the SCAR series sometime before 2012 in the Armaverse.
    • This is completely inauthentic to real-life however, as neither the 5.56 mm nor the 7.62 mm variants of the SCAR were considered for adoption at any point by conventional U.S. forces.
    • Some special forces units did end up adopting the SCAR platform in limited numbers, but simply to complement the M4A1 rather than fully replace it.
  • The M4A3 has several unused variants that are not configured for use in-game. Notably, this includes a variant that has no optics mounted and lacks a carryhandle, another that uses an ACOG riflescope and laser pointer, as well as a variant that uses a Trijicon "RX-01" reflex sight that can also be found on the Sa-58.
