The Mk4 BANSHEE is built on has a standard AR15-pattern lower receiver and utilizes 9mm AR conversion magazines. While not only having the same manual of arms as any AR15, you can convert your existing stash of PMAGs to 9mm using CMMG 9 AR conversion adapters. 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, you’ll always have enough space for those must-have accessories.
Originally developed for the .45 ACP MkG platform, CMMG adapted their Radial Delayed Blowback system across the pistol caliber lineup to create pistols and rifles with a softer recoil impulse and reduced bolt weight compared to traditional straight blowback systems.
