The Heckler & Koch HK416 is an assault rifle chambered for the 5.56×45mm NATO cartridge, designed and manufactured by the German company Heckler & Koch. Although the design is based on the selective fire M16 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 the Heckler & Koch G36 family of rifles.

The HK416 has been adopted by various military forces and is used by many special operations units worldwide. The Norwegian Armed Forces had adopted the HK416N as their standard issue rifle in 2008. The United States Marine Corps has adopted a modified variant, designated as the M27 Infantry Automatic Rifle to replace the M249 SAW, and eventually also the M16A4, M4 and M4A1. The HK416F has been selected by the French Armed Forces to replace the FAMAS in 2017. The HK416 A5 is in service with the Irish Army Ranger Wing. The German Army had adopted a variant of the HK416, designated as the G95A1 to replace the Heckler & Koch G36 as their standard issue service rifle.
