« The XM8 was the US Army project name for new lightweight assault rifle system. US Army hoped to create new standard and highly modifiable infantry rifle but in 2005, the project was formally canceled. ~7500 prototypes of this weapon still exist, now held by the US Army.

The weapon was designed to use 5.56x45mm NATO cartridges and is able to fire up to 750 rounds per minute.

All variants of the XM8 (including the XM8 Automatic Rifle) can be loaded with six types of 5.56 mm magazines. The 100-round drums take up two inventory slots but regular 20- and 30-round magazines use one slot only:

G36 Mag.


Standard 30-round plastic magazine. Also shared with the G36 family.

Does not contain any visible tracers.

30rnd G36 SD


Loaded with subsonic 5.56 mm ammunition. It fires rounds with greatly reduced velocities of 320 m/s, but remain otherwise identical to regular plastic magazines.

MG36 Mag.


100-round Beta-C drum specifically intended for use with the XM8 Automatic Rifle variant.

Aside from its capacity it is completely identical to regular 30-round plastic magazines.



Alternate 30-round magazine used by M16A4 rifles and M4A1 carbines.

It is largely identical to the XM8's standard plastic magazines, but rounds fired from this magazine specifically have a slightly higher muzzle velocity of 930 m/s instead.



Specialised magazine loaded with subsonic 5.56 mm ammunition. Identical to regular 30-round STANAGs save for a much lower velocity of 320 m/s.



20-round box magazine. Remains otherwise identical to regular 30-round STANAGs.


  • As mentioned in its Armoury Description, the real-life Heckler & Koch "XM8" rifle was originally slated to replace both the "M16" rifle and "M4" carbine series of weapons throughout the U.S. Armed Forces prior its formal cancellation in 2005.
  • Along with the Mk16/Mk17 family, it is one of the few modular rifle platforms that are currently available for use in ArmA 2. It would only be matched by the MX series in ArmA 3, which is almost identical to the XM8 in terms of the types of variants that it has.
    • The ability to load and feed from Beta-C drum magazines is a capability that is unique to both the G36's MG36 variant as well as the SPAR-16S that would eventually be added with ArmA 3's Apex DLC.
  • Though it was actually included on ArmA 2's release, the XM8 family only included the basic variants without additional optical sights and accessories, while also remaining unused by any faction prior to the release of the Private Military Company DLC.
  • Hidden models and textures for the XM8 were previously available in ArmA: Armed Assault. They were eventually removed after the release of Patch 1.08 however, which implies that they were intended to make their debut in that game instead of in ArmA 2.
