M4

An M4 Carbine is a type of assault rifle.

Details
Favoured by counter terrorist and special forces units due to its combination of lightness, compactness and solid all round performance (especially in close quarters combat), the M4 has a fast rate of automatic fire and is impressively accurate at all but extreme distances.

Configured to mission specs, the M4 may include detachable grenade launcher, infared illuminator, night-vision sight, and visible laser.
