The HK416 A5 with 14.5-inch barrel is the compact service configuration closest to the military M4-length HK416 used by JSOC and other tier-one units. The short-stroke gas piston system eliminates the direct impingement carbon fouling of the M4 platform while maintaining compatibility with all AR-15/M16 magazines and most accessories. The A5 generation added a fully ambidextrous lower, improved bolt carrier, and enhanced charging handle.
