Heckler & Koch MR762 A4 13-Inch Threaded Barrel 7.62x51 NATO Pistol

The Heckler & Koch MR762 A4 pistol combines a match-grade cold-hammer-forged barrel with HK's reliable gas-operated short-stroke piston system. Its 13-inch barrel is threaded 5/8x24 for suppressor use, and an adjustable gas regulator allows tuning for suppressed or unsuppressed shooting. A continuous Picatinny rail provides a stable optic-mounting interface, while the M-LOK handguard adds flexible accessory placement and integral ambidextrous QD cups. Ambidextrous controls, an extended charging handle, a two-stage trigger, and HK's enhanced ergonomic grip support confident handling in a wide range of configurations.
