Semi-automatic, AR Type
The MR762A1 is Heckler & Koch’s long anticipated 7.62 x 51 mm semi-automatic rifle. Manufactured in the USA of American and German components, the MR762A1 completes the MR Series (for Match Rifle) of HK’s civilian/commercial rifles, joining the 5.56 mm model (MR556A1) introduced in 2011. The new MR762A1 rifle is inspired and influenced by several recent Heckler & Koch piston driven rifles designs, including the new HK G28 designated marksman rifle developed for the German military. A semi-automatic rifle originally developed from the fully automatic HK417, the MR762A1 uses the same unique operating rod gas system pioneered by HK in the G36, XM8, HK416, and HK417 weapon systems. This system uses a gas piston and pusher rod operating system in place of the more common hollow gas tube normally employed in AR-style rifles. The HK system improves reliability and reduces operator cleaning and maintenance as literally no carbon fouling or propellant gases are directed back into the weapon beyond the gas cylinder located above the barrel. Like its military counterparts, the design goal of the MR762A1 is to ensure no stoppages or parts failures even after tens of thousands of rounds are fired. The MR762A1 uses many of the same assemblies and accessories that originated on the HK417 including the HK free-floating four-quadrant rail system. This handguard system allows all current accessories, sights, lights, and aimers used on M4/M16-type weapons to be fitted to the MR Series. The HK rail system can be installed and removed without special tools and returns to zero when reinstalled. Like their HK military counterparts, the MR series arms use barrels produced by Heckler & Koch’s famous cold hammer forging technology. The highest quality steel is used in this manufacturing process, producing a long-life barrel that provides superior performance with minimal degradation of accuracy and muzzle velocity, even after prolonged service. The barrels are manufactured in Germany and finished in the USA. The MR762A1 barrel 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. The thick, heavy contour 16.5-inch MR762A1 barrel also contributes to its excellent accuracy. A precise, enhanced two-stage trigger adds significantly to the accuracy of the MR7626A1 and an extended latch charging handle makes operating the rifle with a telescopic sight easier. The retractable buttstock can be locked into a fixed, non-moving position by tightening an Allen screw in the bottom of the stock. Special target rifle takedown pins ensure the upper and lower receivers are firmly mated together for maximum accuracy. Designed to function with a wide variety of high quality 7.62 x 51 mm ammunition, the MR762A1 uses a C.I.P. dimensioned chamber (a chamber with dimensions specified by the Commission Internationale Permanente). The MR762A1 also functions reliably with most high quality Caliber .308 Remington ammunition. The MR762A1 is being produced with the same commitment to quality as German-made HK firearms. By using joint U.S./German manufacturing, Heckler & Koch leverages the relative strengths of two continents to make the preeminent AR-type firearms, combining the design innovations of the USA and Germany into superior products. MR762A1 rifles are well-suited for a variety of applications including law enforcement tactical, police patrol, general sporting, and hunting (a 5-round magazine is under development).
