H&K MR762 A4 | 7.62x51mm | 16.50″ P/N 81001205

The MR762 A4 is a semi-automatic 7.62x51mm rifle built around Heckler & Koch’s short-stroke gas piston system for reduced carbon fouling and extended service life. The platform features an adjustable gas regulator for tuning suppressed or unsuppressed operation, fully ambidextrous controls, and a slimmer profile for easier handling. This configuration pairs well with a modern low- to mid-magnification optic; consider a Vortex Viper PST Gen II 1-6×24 for reliable, sub-$1000 performance and a clear sight picture out to typical engagement ranges. Applications include precision semi-automatic target shooting and medium-range field/tactical training.
