The HK MR556 is arguably the best if not one of the best piston operated AR type rifles in the world. This gas piston method of operation virtually eliminates malfunctions that are common to direct impingement gas systems. Whereas carbon heat and fouling accumulate in bolt carrier groups of a traditional direct gas impingement rifles, a piston rifle disperses these materials into the upper hand guard. This is the exact same operating system as the HK416 military designated rifle.

The HK Free Floating Rail System (FFRS) handguard has four MIL-STD-1913 “Picatinny” rails and allows all current accessories, sights, lights, and aimers used on M4/M16-type arms to be fitted to the MR Series. The HK rail system can be installed and removed with simple tools and returns to zero when reinstalled. The MR556-A1 utilizes one of the finest cold hammer forged heavy barrels on the market. It is Melonite dipped for strength and unlined for accuracy. Barrel contour is slightly "swagged" at the tip meaning it tappers down at the muzzle. Twist rate is a versatile 1/7.

Weapon includes an HK factory soft case. Please call us if you have questions. Weapon will ship the same day as your transaction if we have your ship-to-FFL paperwork before 3:30PM Mountain Standard Time.
