HK MR556 OR Rifle 30 RD 16.5

Product Description

A direct descendent of the HK416, the HK MR556 OR rifle 30 RD 16.5 is a semi-automatic rifle developed by Heckler & Koch as a premium level commercial/civilian firearm with match rifle capability. Like the HK416, the MR556 is a major product improvement over conventional AR-type carbines and rifles. Designed to function with a wide variety of high quality 5.56 x 45 mm ammo and uses a C.I.P. dimensioned chamber. It uses the H.K. proprietary gas piston operating system. It employs a piston and a solid operating ‘pusher’ rod instead of the gas tube commonly found in certain firearms. When unforgiving operating conditions involve dust, dirt, sand, and mud, the HK MR556 OR rifle 30 RD 16.5 stands out from the competition with its ability to power through without fail. The unchromed barrel is forged from the highest quality cannon-grade steel with a tapered profile. Providing an internal profile of 6 lands and grooves with a 1 in 7 inch (178 mm) twist. It is also moderately ‘swagged’ with a slightly smaller internal diameter at the muzzle end than the chamber end. This feature has a positive effect on bullet accuracy and velocity.
