Description
Product Overview
The Heckler & Koch MR556 A4 is an AR-style pistol built around HK’s short-stroke gas piston operating system. By keeping hot carbon fouling out of the action, the system supports extended operation with reduced maintenance and less wear on internal components. Its adjustable gas regulator allows tuning for suppressed or unsuppressed use, while fully ambidextrous controls provide convenient operation from either side. The 11-inch threaded barrel offers a compact handling profile and supports compatible muzzle devices and suppressors.
