HK MR762 A4 7.62x51mm 13" Threaded 20+1 Semi-Auto Pistol

The HK MR762 A4 is a semi-automatic 7.62x51mm pistol built on Heckler & Koch's battle-proven AR-10 platform. This A4 variant pairs a 13" cold hammer forged barrel with a 5/8x24 threaded muzzle, an M-LOK handguard, and a black upper and lower receiver topped with a full-length Picatinny rail. An adjustable gas regulator allows reliable cycling whether shooting suppressed or unsuppressed.

Configured as a true pistol, the MR762 A4 uses a black pistol buffer tube in place of a stock, keeping overall length to a compact 31.4" at a weight of 7.95 lbs. Controls include an ambidextrous safety lever and an ergonomic pistol grip, with the action fed from a 20-round detachable magazine for a 20+1 capacity. Optics-ready with no iron sights installed, the MR762 A4 is ready to mount your preferred red dot or magnified optic on the integrated Picatinny rail.
