The battery is located in the stock. It is modelled after the Crane stock one and fits Crane type batteries.

The M4 carbine is a family of firearms that was derived from earlier carbine versions of the M16 rifle, which was in turn derived from the original AR-15 rifle that Eugene Stoner designed and ArmaLite made. The M4 is a shorter and lighter variant of the M16A2 assault rifle. It is a gas-operated, magazine-fed, selective fire, shoulder-fired weapon with a telescoping stock and 14.5 in (370 mm) barrel to ease close quarters combat. Like the rest of the M16 family, it fires the .223 caliber, or 5.56mm NATO round.
The M4 carbine is heavily used by the U.S military. It will eventually replace the M16 rifle for most combat units in the United States Army. The winner of the Individual Carbine competition was to supplement the M4 carbine in U.S. Army service; all other services will continue using the M4 carbine and M16 rifles. The Army cancelled the Individual Carbine competition without selecting a replacement rifle and instead plans to equip soldiers with the improved M4A1.
