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


The M4A1 is a 5.56 mm carbine featured in both ArmA: Armed Assault and ArmA 2.

ArmA: Armed Assault

« 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, an M203 underbarrel grenade launcher, and many others.

The M4A1 is used by both U.S. Army forces and Black Element PMCs in ArmA: Armed Assault.

Overview

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

It loads from 30-round STANAG magazines and can attain a fire rate of up to 667 rounds per minute, and has a muzzle velocity of 850 m/s. The M4A1 features a suppressed sub-variant, and can also be fitted with either a red dot sight or ACOG riflescope.

A modular weapon platform, the M4A1 serves as the standard-issue weapon utilised by U.S. military forces deployed to Sahrani.

It is largely comparable to the longer M16A4 assault rifle, though its shorter-length barrel reduces its inertia penalty on the user and makes it easier to handle in close quarters.

Accuracy-wise, the M4A1 has almost twice the dispersion of the M16A4 at distances of beyond 300 metres. In all other aspects the M4A1 isn't that much different to the M16A4 nor its older predecessor, the M16A2.

The M4A1 GL is simply a modified variant of the baseline M4A1 carbine that has an underbarrel grenade launcher attached to it.

The M203 GL can fire a mixture of either 40 mm high-explosive (HE) or flare grenade rounds. It is accurate at ranges of up to 300 metres. The weapon itself is otherwise unchanged (performance-wise) to regular M4A1s.

The M4 is another variant of the baseline M4A1 carbine.

Unlike stock M4A1s, the M4 is only capable of toggling between a semi-automatic or three-round burst fire mode and cannot switch to firing on full-auto. It remains otherwise unchanged to the regular M4A1.

Trivia

  • Armed Assault is currently the only title in the series to feature the burst fire-only variant of the M4 carbine.

The M4A1 is used by the U.S. Marines and in limited numbers with ION PMC bodyguards in ArmA 2.

Overview

Returning from Armed Assault, the M4A1 still serves as an alternate counterpart to the M16A4 assault rifle used by the U.S. Marines.

It still loads regular 30-round STANAG magazines used by other 5.56 mm weapons like its rifle counterpart, and has the same fire rate of its predecessor.

Its muzzle velocity has been increased to 930 m/s however, and now has several variants fitted with different optical sights ranging from the CCO red dot 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

Primarily wielded by USMC vehicle crewmen, Navy Corpsmen and Force Recon operatives deployed to Chernarus, the M4A1 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.

Like in Armed Assault, its carbine configuration results in the M4A1 being less accurate than its rifle counterpart at distances of beyond 300 metres. As a result, it shouldn't be used to engage targets 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

  • 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

  • The ArmA 2 M4A1 models (not the M4A3 variants) are simply updated ports of the Armed Assault M4A1.
  • Both the M4A1 and its long barrel rifle counterpart are shown to have been completely replaced in U.S. military service by the SCAR series sometime before 2012 in the Armaverse.
    • This is completely unauthentic 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.
