MR762A1 Rifle 7.62mm NATO 16.5 Inch Barrel Black Finish Adjustable Polymer Stock 20 Round
Gas operated, short stroke piston. Two stage trigger. Five-position adjustable stock. Cold hammer forged 16.5 inch barrel with a 1:12 inch right hand twist rate.

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 common gas tube 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. The service life of all parts is increased substantially. The MR762A1 uses a barrel hammer-forged of the highest quality steel with 4 grooves, ensuring superior accuracy, even after firing thousands of rounds. The MR762A1 is produced at H&K's American facilities using both American and German-made components. The MR762A1 uses many of the assemblies and accessories originally developed for the HK416/417 series including adjustable buttstocks, ergonomic pistol grips, mechanical sights, and the HK free-floating four-quadrant rail system/handguard. This MIL-STD-1913 Picatinny type rail system allows all current accessories used on M4/M16-type weapons to be fitted to the MR series. The HK rail system can be removed without special tools by the user and ensures 100% return to zero when reinstalled. Ambidextrous operating controls are standard on the MR762A1, including a convertible charging handle and an ambidextrous selector lever. The MR762A1 uses the same 10- and 20-round translucent polymer box magazines made for the HK417.
