H&K MR762 A4 Pistol | 7.62x51mm | 13in | 81001053

The HK MR762 A4 is the commercial MR variant of the HK417 series configured as a 13-inch pistol-length system that keeps HK’s emphasis on reliability and ergonomics. It features a threaded, cold-hammer-forged barrel and a fully ambidextrous lower with modern HK416-style slimline furniture. For optics, this platform pairs well with a low-power variable such as the Vortex Viper PST Gen II 1-6×24 for fast target acquisition and 7.62 performance under $1,000.
