Heckler & Koch® MR556A1 Competition Semi-automatic 5.56 NATO AR Rifle. Created with input from special forces. Perfected for the 3-gun match shooter!
From the innovative OSS flash hider to the Magpul® CTR collapsible stock, the MR556A1 Competition Rifle represents the finest quality and craftsmanship available to civilians today! Quality-built from premium U.S. and German components in HK's Newington, New Hampshire manufacturing facility, the MR556A1 represents the new benchmark for AR rifle design.
And it all starts with the gas piston operating system, which utilizes a piston and a solid operating "pusher" rod in place of the gas tube normally found in AR15 / M16 / M4-style firearms. This method of operation virtually eliminates malfunctions that are common to direct impingement gas systems since hot carbon fouling and waste gases do not enter the receiver area.
Add in a premium German-made, cold-hammer-forged barrel, a free-floating modular rail system, and exceptional two-stage trigger, and you're looking at a true match-grade performer. Why settle for less?
