The MR556 series is a civilian adaptation of H&K’s renowned 416 service rifle. It features the brand’s proprietary short-stroke gas piston system, which ensures cleaner and cooler operation compared to traditional direct impingement AR-style rifles. A tungsten-filled buffer tube helps slow the bolt carrier during firing, enhancing reliability and reducing felt recoil.

This rifle is equipped with a heavy-profile, non-chrome-lined barrel, designed to optimize precision beyond the traditional chrome-lined barrels of the 416. With a 1:7 twist rate, it effectively stabilizes a variety of ammunition, from standard 55-grain M193 rounds to heavier OTM loads preferred by precision shooters and specialized units. H&K’s renowned manufacturing quality ensures exceptional barrel longevity and sustained accuracy.

This special edition model celebrates Heckler & Koch's 75th anniversary and features a distinctive Flecktarn camouflage finish. Limited to only 500 units, it comes with four 30-round magazines and a carrying case.
