MMG® BansheeTM Mk17 9mm Semi-automatic AR-style Pistol

Engineered to accept SIG SAUER P320/M17 magazines, the CMMG Banshee Mk17 delivers a new level of performance to the AR pistol world. At the top of the list of high-performance features is the Radial Delayed Blowback operating system: unlike typical blowback systems, Radial Delayed Blowback not only reduces the weight in your BCG, it also reduces felt recoil—allowing you to stay on target and make faster follow-up shots.

But there's more to the Banshee than its unique operating system. It comes loaded with CMMG's own ZEROEDTM components front to back. ZEROED components are American-made to deliver a much higher level of performance than standard mil-spec. Even better, the new EML 4 handguard provides outstanding stability without unnecessary weight. M-LOK attachment slots are found where expected at the 3, 6, and 9 o’clock positions, as well as a full-length Picatinny top rail.

Pair the Banshee with your existing M17 or P320, and you’ve got the convenience of magazine interchangeability and the versatility for any scenario.
