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 with the notable inclusion of a gas-piston system derived from the Heckler & Koch G36. Customers have the option of purchasing a new upper receiver, buffer and drive spring to refurbish M4s or buying a completely new build HK416. The HK416 is part of the Individual Carbine competition to replace the M4.
