Designed around CMMG’s proven rimfire architecture, this BANSHEE configuration uses dedicated .22 components for smooth cycling and consistent accuracy.

Lightweight, Ultra-Compact Handling The BANSHEE line is built for short overall length and quick transitions. It’s easy to maneuver around barricades, vehicles, and tight indoor lanes while staying stable on target. Accessory-Ready Modularity Free-float handguard and full-length Picatinny optics rail (configuration dependent) make it simple to mount a red dot, LPVO, offset irons, white light, hand stop, QD sling sockets, and more. Clean, Modern Finish The AR Black (ARBLK) coating pairs a professional aesthetic with excellent durability against the elements, solvents, and heavy range use.
