The Heckler and Koch MR556 A4 represents the latest enhancement to HK's Legendary MR556/416 family of piston-driven carbines. The short-stroke gas piston system keeps hot fouled gas from entering the receiver, reducing and simplifying maintenance while enhancing reliability and durability. An adjustable gas system can be tuned for adverse conditions and suppressor use. If you're in the market for a top-tier carbine built to exact German engineering standards, look no further than the H&K MR556 A4!
Features:
The H&K MR556 A4 pistol improves on its predecessors with a lighter and slimmer construction, making it much more handy and more maneuverable. The 11" high chromium barrel offers exceptional accuracy and durability, with a 1:7 twist rate to stabilize heavier match-grade ammunition. The MR556 A4 is perfectly suited for use as an SPR or in competition, as well as defensive and duty work.
