Description: This rifle comes with one 30-round heavy-duty all steel HK magazine.

Catalog Ref: HKGMR556A1

Based on the standard M4-style rifle, and still chambered in 5.56×45mm, the MR556 dispenses with the old gas impingement system of operation for a new, proprietary short-stroke gas piston system. The piston system vastly improves the reliability of the weapon and virtually eliminates the usual fouling found on most AR rifles. With less fouling, less lubrication is needed. Improvements over the M4 certainly don’t stop at the gas system, however. In fact, the MR stands for Match Rifle and the gun is built for accuracy more so than its progenitor the HK416.

This rifle has a 16.5-inch cold hammer forged, heavy barrel with 1-in-7-inch right-hand twist rate with six lands and grooves and topped off with an A1-style flash hider/compensator. The MR556 dispenses with a chrome-lined barrel since HK engineers determined that an unlined bore delivers better accuracy. Chrome-lining barrels can help extend the life of the barrel but inconsistencies in the chrome thickness can work against maximum accuracy.

To further enhance accuracy, the barrel of the M556 is slightly “swagged”, which means that it narrows in its internal diameter as it nears the muzzle end, improving both accuracy and bullet velocity. The end result is an outstandingly accurate barrel with a life expectancy without degradation in excess of 20,000 rounds.
