HK MR556 A4 Rifle- 8100027. Semi automatic 5.56/.223 AR15 rifle with a 16.5″ cold hammer forged barrel. Its short-stroke gas piston operating system does not impart hot carbon fouling back into the action, allowing the weapon to run longer, with less maintenance and with less wear on internal components than direct-impingement ARs. The MR556 A4 also includes ambidextrous controls for enhanced usability, making it an ideal choice for both right and left-handed shooters. This rifle excels in home defense and sport shooting and has the classic Heckler & Koch reliability and durability. 30 Round capacity.
