The CMMG® MK4 Semi-Auto Rifle in Marsh Green Cerakote® with FDE Furniture checks all the boxes you want in an AR-15. This CMMG rifle features a marsh-green Cerakote finish to protect the metal components from the elements in the field. This MK4 features flat dark earth accents on the B5 stock and pistol grip as well as a CMMG magazine, adding a nice camo-style contrast to this rifle. A full-length, wedge lock, free-floating M-LOK® handguard is designed to accept numerous accessories available. CMMG ZEROED® controls include an ambidextrous safety selector designed to accommodate left-handed shooters and right-handed shooters. Muzzle brake is fitted on the threaded barrel to reduce felt recoil.
