CMMG Banshee MK4 9mm 5" 30+1 Semi-Auto Pistol - Armor Black

The CMMG Banshee MK4 is a compact 9mm Luger AR-platform pistol chambered for the 9x19 Parabellum cartridge. Built around a 5" 4140 Chrome Moly barrel and finished in Armor Black Cerakote, the Banshee combines familiar AR-style controls with 9mm pistol-caliber operation suited for training, home defense, and recreational range shooting.

This MK4 variant feeds from a 30-round detachable magazine and operates via a semi-automatic action. The upper is fitted with a slim EML 4" M-LOK handguard for accessory mounting, and the lower carries a CMMG 6-position Fastback receiver extension paired with a CMMG RipBrace for stabilized shooting. Controls include the CMMG Zeroed 60/90 degree ambidextrous safety selector and the CMMG Zeroed polymer pistol grip. Sights are not included, allowing the user to pair the pistol with their preferred red dot or iron-sight setup.

Weighing in at 5 lbs with an overall length of 20.80", the Banshee MK4 is a compact, maneuverable 9mm AR pistol suited to short-range defensive roles and range work. One 30-round magazine is included.
