The CMMG Banshee Mk4 pistol in 9mm with an 8-inch barrel and Midnight Bronze finish (brand part no. G94A860FMB) is built on a standard AR15-pattern lower receiver that runs CMMG’s 9mm AR conversion magazines, giving shooters the same manual of arms as a centerfire AR15. CMMG pairs the barrel with an EML M-LOK handguard that runs full-length M-LOK slots on both sides and the bottom, plus M-LOK between the top Picatinny rail sections. The pistol ships optics-ready with an ambidextrous safety and a quick-deploy CMMG RipBrace, feeding from a 30-round magazine. Among AR pistols, this Banshee Mk4 favors shooters who want to run their existing PMAG stash in 9mm.
