Sturmgewehr G95K
While the HK416 family may look like any old AR15, they are piston guns rather than the more traditional gas impingement system familiar to the Stoner design. Ironically, the proprietary short-stroke gas piston system is derived from the G36 family, which, in turn, owes a lot of groundwork to Stoner’s AR-18 design. The 416 has proven popular enough to be selected as the main infantry weapon for the French and Norwegian militaries as well as to be fielded by the U.S. Marines as the M27. (Photo: Bundeswehr)
