M4/M4A1 5.56mm Carbine

The M4/M4A1 5.56mm Carbine is a lightweight, gas operated, air cooled, magazine fed, selective rate, shoulder fired weapon with a collapsible stock. Equipped with a shorter barrel, collapsible stock and accessory rails it provides soldiers operating in close quarters with improved handling and the capability to rapidly and accurately engage targets at extended range, day or night. A shortened variant of the M16A2 rifle, the M4 provides the individual soldier operating in close quarters the capability to engage targets at extended range with accurate, lethal fire. The M4 Carbine achieves over 80% commonality with the M16A2 Rifle and will replace all M3 .45 caliber submachine guns and selected M9 pistols and M16 rifle series.
