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.
