CMMG Banshee Mk4: Purpose-Built for Suppressed 9mm Shooting
The Banshee Mk4 represents a thoughtful approach to suppressed 9mm rifle shooting. Chambered in 9mm Luger and paired with the Zeroed 36 suppressor, this platform delivers the quiet, controllable performance that modern shooters demand.
Operating System
The Fixed Ejector Radial Delayed Blowback system is the heart of this design. Unlike traditional direct impingement, this operating system cycles at lower pressures—ideal for suppressed ammunition. The result is reduced recoil, faster target reacquisition, and a shooting experience optimized for sound suppression.
Controls and Ergonomics
CMMG equipped the Banshee Mk4 with premium Zeroed controls:
- Ambidextrous charging handle for shooters of any hand preference
- Single-stage drop-in trigger for crisp, predictable breaks
- 60/90 ambidextrous safety selector positioned for intuitive operation
- Standard AR15 magwell compatible with CMMG's 33-round or 10-round 9mm magazines
What's Included
You receive a 33-round magazine and silicone handguard covers that snap into M-LOK slots. Position these covers where they work best for your grip and hand comfort—a small touch that shows attention to shooter needs.
The Platform
The Mk4 lower receiver maintains AR15 compatibility, making this platform familiar to anyone with modern rifle experience. Whether you're new to suppressed shooting or a seasoned practitioner, the Banshee Mk4 delivers reliability and performance without unnecessary complexity.
