The HK MR762 A4 Upper Receiver Kit is a factory-built upper receiver and barrel assembly designed for the MR762/7.62 NATO platform. Built around HK's short-stroke piston operating system, it helps keep heat, carbon, and fouling out of the receiver for enhanced reliability and easier maintenance. This complete assembly features a 13-inch barrel with 5/8x24 muzzle threads, a free-floating handguard, and an adjustable gas block to tune the rifle for different conditions and suppressor use. Includes bolt group assembly plus HK proprietary buffer components; ships in an HK soft case.
