M4A1 Testing Click to Shot R to Reload Q to Raise Weapon
The M4/M4A1 5.56mm Carbine is a lightweight, gas operated, air cooled, magazine fed, selective rate, shoulder fired weapon with a collapsible stock. It is now the standard issue firearm for most units in the U.S. military. Equipped with a shorter barrel, collapsible stock and detachable carrying handle (with a built-in accessory rail) 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 carbine provides the individual soldier operating in close quarters the capability to engage targets at extended range with accurate, lethal fire. The M4-series Carbine achieves over 80% commonality with the M16A2 Rifle and replaces all M3 .45 caliber submachine guns, and selected M9 pistols and M16 rifles.
