Like its 5.56mm counterpart, the MR762A1 is a direct descendant of the HK416/417 series, but in a semi-automatic rifle configuration developed for civilian users. Using the HK-proprietary operating system, the MR762A1 is gas operated and uses a piston and a solid operating "pusher" rod in place of the gas tube normally employed in AR15/M16/M4-style weapons. This method virtually eliminates malfunctions common to direct impingement gas systems since hot carbon fouling and waste gases do not enter the receiver area. The MR762A1 stays cleaner, reducing heat transfer to the bolt and bolt carrier, and drastically reducing wear and tear on other critical components. HK's cold hammer forging process uses the highest quality steel, producing a barrel that ensures superior accuracy, even after firing thousands of rounds. It features many of the assemblies and accessories originally developed for the HK416/417 series including adjustable buttstock, ergonomic pistol grip, mechanical sights, and the HK free-floating four-quadrant rail system/handguard. This MIL-STD-1913 Picatinny rail system allows all current accessories, sights, lights, and aimers used on M4/M16-type weapons to be fitted to the MR series. Many ambidextrous operating controls are standard on the MR762A1, including a convertible charging handle and an ambidextrous selector lever. It includes a 10-round polymer box magazine.
