The MR556 A4 SBR, HK-USA’s latest update to the commercial variant of the renowned HK416, exemplifies HK’s “no compromise” performance. Featuring a short-stroke gas piston system that prevents hot carbon fouling from entering the action, it delivers longer run times, reduced maintenance, and less wear compared to direct-impingement ARs. An adjustable gas regulator allows precise tuning for both suppressed and unsuppressed use, while fully ambidextrous controls, reduced weight, and a slimmer profile enhance handling and ease of operation. For shooters seeking an AR platform with superior capability, reliability, and durability, the MR A4 series stands as the premier choice.
