Like its 5.56 mm counterpart, the MR762A1 is a direct descendent of the HK416/417 series, and uses the HK-proprietary gas operated piston system in place of the common gas tube normally employed in certain firearms.

Pioneered by Heckler & Koch in the G36, HK416, and HK417; 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 produced by Heckler & Koch’s famous cold hammer forging process. This manufacturing process uses the highest quality steel, producing a barrel that ensures superior accuracy, even after firing thousands of rounds. The MR762A1 is produced at Heckler & Koch’s American manufacturing facilities from 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, sights, lights, and aimers 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; a 5-round magazine is also under development. MR762A1 rifles are well-suited for a variety of applications including law enforcement tactical, police patrol, general sporting, and hunting.

The best all around battle weapon out there. Much better than the FNAR HEAVY. And as far as your 2.5" groupings at 100 yards that can be due to the quality of your ammunition, weather conditions or skill level.

This rifle shot a one inch group at 200 yards with match ammo, am so pleased with weapon I am ordering one in 5.56. The quality of the weapon is impeccable I wish the one I carried on patrol in Vietnam was as well made.

Most accurate semi-auto 7.62 that I have ever fired. Yes, I have spent quite a bit of range time with various rifles including the M-14 during my time in the Marine Corps. Sure, it is expensive but you get exactly what you pay for and you never regret buying the very best but you can certainly be disappointed when you don't. This rifle is not for everybody...just those who want the top of the line.

Dropped a Schmidt 5-20 Ultra Short on mine and it's as good as a semi gets. Nothing can compare.
