mr556

The Heckler & Koch HK416 is a rifle designed and manufactured by Heckler & Koch. Although its design is based on the AR-15 class of weapons, specifically the Colt M4 carbine family issued to the U.S. military, it uses a proprietary short-stroke gas piston system derived from the ArmaLite AR-18 (the same system was also used in Heckler & Koch's earlier G36 family of rifles). It is the standard assault rifle of the Norwegian Armed Forces, selected by the French Armed Forces to replace the FAMAS, and was the weapon used by SEAL Team Six to kill Osama Bin Laden in 2011.
