H&K MR762 A4 SBR | MFG# 81001054

The MR762 A4 SBR is a short-barreled rifle built for durability and sustained use. Its short-stroke gas piston operating system reduces carbon fouling in the action, and an adjustable gas regulator lets the operator tune the rifle for suppressed or unsuppressed use. The platform is fitted with an M-LOK-compatible handguard and finished in black anodized surfaces for corrosion resistance. Suggested optic under $1000: Aimpoint PRO red-dot, a robust sight that pairs well with compact 7.62 platforms for close-to-mid-range work.

Common applications include range/training work and professional/tactical roles where a compact, durable 7.62-caliber semi-automatic SBR is required.
