When it comes to size this CMMG Mk47 is the middle child of the bunch. With a 12.5 barrel its the longest configuration in the BANSHEE series, offering the right blend between maneuverability and ballistic performance. The Mk47 platform is CMMGs 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 its not broke why fix it? Available in a variety of cerakote finish options, the BANSHEE series represents the most innovative AR pistols and SBRs available today. From the quick deploying RIPBRACE, to the stylized receivers and EML handguards, every BANSHEE is tailor-made to be the personal defense weapon you can always depend on. With full length M-LOK slots on both sides and the bottom of the handguard as well as M-LOK between the top picatinny rail sections, youll always have enough space for those must have accessories.
