Although it is listed under semi-auto rifles, the CMMG Banshee Mk4 (brand part no. 94AD90F-MB) is actually a 9mm AR-pattern pistol, built on a compact 5-inch barrel with a quick-deploying RipBrace rather than a shoulder stock, finished here in Midnight Bronze. It uses a standard AR-15-pattern lower receiver and CMMG’s 9mm AR conversion magazines, so shooters can convert their existing stash of PMAGs to 9mm using CMMG’s conversion adapters and keep the same manual of arms as any AR-15. It suits shooters who want the smallest practical 9mm AR-pattern pistol for concealed carry in a bag or deep home-defense use. The EML handguard offers M-LOK slots on both sides, the bottom, and between the top Picatinny rail sections.
