When it comes to size this CMMG® Mk47 is the middle child of the bunch. With a 12.5 barrel it’s the longest configuration in the BANSHEE series offering the right blend between maneuverability and ballistic performance. The Mk47 platform is CMMG’s mid-size AR platform utilizing more robust receivers and components like our PowerBolt Technology without adding unneeded bulkiness. If the magwell on the Mk47s looks ready to take AK-pattern magazines you would be right. Since AK magazines were designed around the 7.62x39mm cartridge we figured if it’s not broke why fix it? – Platform Mk47 – Caliber 7.62x39mm – Operating System Direct Impingement – Barrel Length 12.5 – Barrel Twist 1:10 – Barrel Contour MT – Barrel Material 4140CM SBN – Barrel Twist 1:10 – Muzzle Device CMMG ZEROED Linear Compensator – Muzzle Thread 5/8 x 24 – Gas Port Location Carbine – Gas Block 0.750 Non-Adjustable – Upper Receiver Billet 7075 T6 Aluminum – Lower Receiver Mk47 Billet 7075 T6 Aluminum – Hand Guard CMMG EML11 M-LOK – Finish Cerakote Standard – Charging Handle CMMG ZEROED Ambi – Pistol Grip CMMG ZEROED Pistol Grip – Buffer Type Carbine – Receiver Extension CMMG 6 Position Fastback Extension – Stock / Brace CMMG RipBrace – Trigger Type Mil-Spec Single Stage – Trigger Guard Integrated – Safety Selector CMMG ZEROED 60/90 Degree – Magazine Magpul 30rd PMAG – Weight 6.5 lbs – Length 28.7
