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.
The FN SCAR is Belgium's modular special-operations combat assault rifle in 5.56 mm (Mk16) and 7.62 mm (Mk17), adopted by USSOCOM and over a dozen other forces, combining a short-stroke piston with quick-change barrels.
