The Heckler & Koch MR762 A4 is a semi-automatic rifle chambered in .308 Win and 7.62x51 NATO. Its short-stroke gas piston operating system keeps hot carbon fouling out of the action, helping extend service intervals and reduce wear on internal components. An adjustable gas regulator allows the rifle to be tuned for suppressed or unsuppressed use, while fully ambidextrous controls support efficient operation from either side. The 16.5-inch threaded barrel, adjustable synthetic stock, optic-ready rail, and 10-round magazine make this rifle a versatile platform for professional, sporting, and precision applications.
