The CMMG Banshee in 9mm is built on CMMG's innovative Radial Delayed Blowback (RDB) system, which uses radially-locking lugs that cam outward under firing pressure to delay the bolt's rearward travel. This delay reduces felt recoil and bolt velocity compared to straight blowback PCCs. The Banshee accepts Glock-pattern magazines via CMMG's magazine well insert system and ships in pistol or carbine configurations.
