Although the 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.

The HK416 is the standard assault rifle of the Norwegian Armed Forces and the United States Marine Corps (named M27), and it has been selected by the French Armed Forces to replace the FAMAS. Other users of the HK416 include the German Army and the Irish Army Ranger Wing, as well as the US Navy's SEAL Team Six, who used it to kill Osama bin Laden in 2011.
