The Heckler & Koch HK416 is an assault rifle designed and manufactured by the German company Heckler & Koch. Although its design is based on the AR-15 class of firearm, specifically the Colt M4 carbine family issued to the U.S. military, it uses a proprietary short-stroke gas piston system from Heckler & Koch's earlier G36 family of rifles.
Model made in blender.
