The Heckler & Koch HK416 is an assault rifle designed and manufactured by Heckler & Koch. It uses the AR-15 platform, originally conceived as an improvement to the Colt M4 carbine family issued to the U.S. military, with the notable inclusion of an HK-proprietary short-stroke gas piston system derived from the Heckler & Koch G36. Military and law enforcement customers have the option of purchasing a new upper receiver, buffer and drive spring to refurbish existing AR-15s or; buy new build complete HK416s.
