BUY H&K MR556A1-FDE 5.56X45MM | HK MR556A1-FDE 5.56X45MM FOR SALE
The Heckler & Koch MR556A1 is a semi-automatic rifle that is a direct descendant of the renowned HK416 and was created as a high-end commercial and civilian firearm. The HK gas piston and pusher-rod operating mechanism, similar to that of the HK416 and M27, is used by the MR556-A1 in place of the gas tube often found in rifles of the AR15/M16/M4 design. As hot carbon fouling and waste gasses are not ejected into the upper receiver to drive the action, this closed system essentially prevents faults that are typical in direct-impingement gas systems. The HK416’s use by elite military and law enforcement customers depends on this characteristic.
Several of the same parts and assemblies created for the HK416 are used in the USA during the assembly of the MR556A1. It works consistently and fires precisely with a choice of high-quality 5.56mm or.223 ammo. The MR556A1 employs a barrel that is cold hammer forged in Germany from the best cannon-grade steel, similar to the HK416. To make products with greater precision and service life, HK follows a meticulous procedure that takes many steps other manufacturers might skip.
The lining is the main distinction between HK416 barrels and MR556A1 barrels. To ensure longer service life under fully automatic fire, HK416 barrels are coated with chromium. The unlined design of MR556A1 barrels allows for greater accuracy while yet maintaining excellent performance under semi-automatic fire. The MR556A1 barrel features a 1 in 7″ twist and six lands and grooves. It has a taper-bore configuration for better accuracy and velocities, with a slightly smaller internal diameter at the muzzle than at the chamber end.
The MR556A1 is made with the same dedication to excellence as HK weapons that are made in Germany. Heckler & Koch creates the best AR-style firearm by merging German and US design advancements into a single model, taking use of the relative advantages of the two continents.
