The Heckler & Koch MR762 A4 pistol in .308 Winchester/7.62 NATO (brand part no. 81001053) brings HK’s proven short-stroke gas piston operating system to a 13-inch-barrel AR pistol platform. Heckler & Koch cuts the barrel at a 1-in-11 twist to stabilize .308-class bullet weights, and an ambidextrous safety lever runs the controls from either side. The upper ships with no fixed sights, fully optic-ready for a red dot or magnified optic, and one 10-round magazine ships with the pistol. Among AR pistols chambered for full-power rifle cartridges, this MR762 A4 configuration favors shooters who want HK’s piston-driven reliability in a compact package.
