CMMG's Banshee series has been a crowd favorite since it first released, and the 9mm Banshee Mk4 is sure to follow that trend. This series uses CMMG's Mk4 lower receiver, and therefore this 9mm model uses CMMG's 9mm AR conversion magazines. It uses the Radial Delayed Blowback system that was originally designed for the .45 ACP MkG platform. This system delivers a softer recoil impulse and reduced weight compared to more traditional straight blowback systems. The threaded muzzle comes with a Zeroed muzzle break to reduce recoil, making follow up shots even easier. Each pistol also comes standard with a highly durable Cerakote finish to better withstand the elements. Additionally, you get a whole suite of CMMG's Zeroed accessories such as an ambidextrous safety selector, ambidextrous magazine catch, and ambidextrous charging handle for easier one-handed operation. Also, the CMMG EML4 handguard features M-LOK slots at the 3, 6, and 9 o'clock positions and Picatinny rail slots. This allows the end user to easily attach sights, lights, lasers, and more. The CMMG Banshee Mk4 is an ultra-fun and extremely compact package that is sure to be enjoyed by anyone who gets behind one! Note: Due to recent law changes, this firearm WILL NOT ship with a pistol brace.
