HK416

The HK416 is Heckler & Koch's piston-driven re-engineering of the AR-15 platform — widely fielded as a special-forces carbine, France's standard rifle, and the US Marine Corps' M27 Infantry Automatic Rifle.

Heckler & Koch's short-stroke piston re-engineering of the AR-15 — adopted by France as its general-issue rifle, by the US Marine Corps as the M27 IAR, and by numerous special-forces units worldwide.

Overview

The HK416 is a 5.56×45 mm NATO assault rifle developed by the German manufacturer Heckler & Koch. It marries the external layout and handling of the AR-15/M4 family with a proprietary short-stroke gas piston system that replaces the direct-impingement action, dramatically improving reliability under fouling and adverse conditions. The platform has been fielded by elite units since 2004, became the standard French service rifle from 2017, and was adopted by the United States Marine Corps as the M27 Infantry Automatic Rifle, making it the Corps' universal infantry weapon. Special forces from Germany, Norway, the Netherlands and US SOCOM count it among their primary small arms.
