CMMG 86AD60B-AB: Familiar AR controls and modularity? Yes. Chambered in 7.62x39mm? You got it. It uses AK mags? If it ain\'t broke don\'t fix it.

A forward non-reciprocating charging handle allows for quick and easy manipulation without coming off target and the M-LOK handguard with top picatinny rail provides ample mounting space for whatever accessories you please. - Platform Mk47 - Caliber 7.62x39mm - Operating System Compact Action-Direct Impingement - Barrel Length 16.1 - Barrel Twist 1:10 - Barrel Contour MT - Barrel Material 4140CM SBN - Barrel Twist 1:10 - Muzzle Device CMMG ZEROED Muzzle Brake - Muzzle Thread 5/8 x 24 - Gas Port Location Mid - Gas Block Adjustable 0.750 - Upper Receiver DISSENT Mk47/Mid-Size 7075 T6 Aluminum - Lower Receiver Mk47 Billet 7075 T6 Aluminum - Hand Guard CMMG 15 Proprietary - Finish Cerakote - Charging Handle Dissent Side Charger Reversible - Pistol Grip CMMG ZEROED Pistol Grip - Receiver Extension DISSENT Folding Stock Adapter - Stock / Brace DISSENT Side Folding Stock - Trigger Type ZEROED Drop-In Single Stage - Trigger Guard Integrated - Safety Selector CMMG ZEROED 60/90 Degree - Magazine (2) Magpul 30rd PMAG - Weight 7.7 lbs - Length 27.6 | 34-37
