Heckler and Koch MR556 A4 Patriot Brown 5.56 11 Barrel 30-Rounds

HK MR556 A4 Features The legendary HK gas piston system reduces fouling and heat transfer into the receiver making the MR556 ideal for demanding shooting environments. A cold hammer-forged 6-groove barrel with a 1:7" twist enhances accuracy and barrel longevity while the M-LOK handguard provides lightweight modularity for accessories. The ambidextrous controls-including the safety selector and charging handle-make this a versatile option for both right- and left-handed shooters. The 6-position adjustable synthetic stock allows for a customized fit and stable shooting stance even in dynamic situations. A full-length Picatinny rail on the receiver offers optimal space for optics irons or laser modules and the lack of factory sights gives you freedom to configure as needed. With its smooth 4.5-5.6 lb trigger pull and sleek design the MR556 A4 offers exceptional control durability and battlefield-proven engineering.
