The Heckler & Koch MR556 A4 is a premium, semi-automatic short barreled rifle (SBR) chambered in 5.56 NATO, built for shooters who want HK’s renowned fit, finish, and performance in a compact NFA platform. Featuring an 11-inch threaded barrel with a 1/2x28 thread pitch, it is suppressor- and muzzle-device-ready while maintaining a highly maneuverable overall package. Finished in durable black anodizing, the MR556 A4 pairs modern ergonomics with rugged construction for hard use on the range or in professional applications.
Outfitted with a free-float M-LOK handguard, this rifle provides ample mounting real estate for lights, lasers, grips, and other accessories without compromising barrel harmonics.
