The Heckler & Koch MR762A1 with an M-LOK handguard is a premium, semi-automatic, match-grade rifle chambered in 7.62x51mm NATO (.308 Win). Directly derived from the legendary HK417 combat rifle, it is widely utilized as a designated marksman rifle (DMR) due to its exceptional accuracy and legendary duty-grade reliability. EXCELLENT CONDIITION OEM RIFLE CASE & OWNER'S MANUAL THREE 20-RD MAGAZINES INCLUDED Key Specifications Barrel: 16.5-inch cold hammer-forged, medium-contour barrel made from cannon-grade steel. It features a 1:11" twist rate and a standard 5/8x24 thread pitch for muzzle devices. Operating System: Proprietary HK short-stroke gas piston system. This closed design prevents hot exhaust gases and carbon fouling from entering the upper receiver, allowing the rifle to run cooler, cleaner, and more reliably in harsh conditions. Handguard: Modern aluminum M-LOK rail system, providing ample mounting space for optics, lights, lasers, and bipods while reducing overall front-end weight compared to older Picatinny quad-rails. Trigger: Two-stage match trigger with a crisp pull weight between 4.5 and 5.6 lbs. [1] Weight & Length: Weighs approximately 9.94 lbs empty. Overall length spans 36 to 39.5 inches depending on the adjustment of the 6-position retractable stock. Magazines: Uses proprietary overbuilt, translucent polymer HK magazines (available in 10-round or 20-round capacities) Core Pros & Cons Pros: Sub-MOA precision capable of reaching targets out to 1,000+ yards; remarkably mild recoil for a .308 platform; ultra-clean piston operation; proprietary receiver pin system that completely removes "wobble" between the upper and lower receiver.
