Heckler & Koch MR762 AR-10 Black 16.5" Barrel 20 Round - 81000586

H&K MR762A1 7.62 x 51 mm

The HK MR762A1 rifle with 16.5” cold hammer-forged, medium contour barrel; 1:12” barrel twist; polymer stock; M-LOK handguard; short-stroke gas piston system; ambidextrous safety lever; 20-round magazine; and black finish.

Offered in a semi-automatic rifle configuration developed for civilian users, the optic ready MR762A1, like its 5.56 mm counterpart, is a direct descendent of the HK416/417 series.

So many of the world’s elite military and law-enforcement customers have absolute trust in this HK firearm because, instead of the direct-gas-impingement system found on lesser AR15-style rifles that propels exhaust gas into the upper receiver to operate the action, the HK MR762 A1 uses a proprietary HK short-stroke gas piston. In the “closed” HK piston system, exhaust gasses never enter the receiver, which means the HK runs cooler, cleaner and more reliably. The advantage of this HK system becomes even more significant in adverse conditions, for instance when dust, sand and mud are introduced.

The H&K MR762A1 is also equipped with a durable and impressively accurate, cold hammer-forged, medium contour barrel made from the highest quality cannon-grade steel; a polymer buttstock; an M-LOK handguard; and an ambidextrous safety lever for easy left and right hand operation.

One (1) magazine of 20 rounds ships with the HK MR762A1 7.62x51 16.25 rifle from Mister Guns.
