The M4A1 is the carbine version of the M16A2, with an adjustable stock and fully automatic firing instead of 3-round burst. Since the M4A1 is much shorter than the M16A2, it is better for close quarters combat.
This variant has an Aimpoint CompM2, designated the 'M68 CloseCombatOptic' by the U.S. military.
This weapon is also known to be rarely found in a Woodland camouflage paint variant.
