The CMMG Banshee Mk17 Pistol (brand part no. 92A2D0FAB) answers shooters’ demand for a pistol-caliber carbine built around the Sig Sauer P320, the pistol adopted by the U.S. military as the M17 and M18. Chambered in 9mm with an 8-inch barrel, the Mk17 uses Sig P320 21-round magazines directly and lets shooters swap magazines seamlessly between the Banshee and a P320 handgun, while retaining full AR-15 functionality and controls. A quick-deploying CMMG RipBrace, a CMMG ZEROED ambidextrous charging handle, and a CMMG ZEROED drop-in single-stage trigger round out a build that weighs just 4.9 pounds and runs 23.7 inches overall. It’s one of the most distinctive pistol-caliber options in the AR pistols lineup from CMMG.
