The HK416 is an assault rifle designed and manufactured by Heckler & Koch. It is a modified version of the American M4 carbine with many changes, most notably a new gas operating system 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.
