Description:
The HK MR556 A1 is a civilian variant of the renowned HK416, chambered in 5.56 NATO. With a 16.5 inch cold hammer-forged barrel, it delivers exceptional accuracy and durability. The rifle"s proprietary short-stroke gas piston system reduces fouling and improves reliability over direct impingement designs. A free-floating M-LOK or quad rail handguard (depending on the model year) allows for optics, grips, and other accessories without barrel interference. The 30+1 capacity standard AR-15 magazines fit seamlessly, and HK"s meticulous engineering ensures smooth cycling. Known for robust construction and attention to detail, the MR556 A1 appeals to enthusiasts seeking a premium AR-platform rifle backed by Heckler & Koch"s legacy of reliability.
