CMMG Banshee MK4 9mm Pistol
The CMMG Banshee MK4 represents a refined approach to modern 9mm pistol design, built on the proven AR platform that shooters trust for reliability and accuracy.
Key Features
- Caliber: 9mm
- Barrel Length: 8 inches for optimal balance of velocity and maneuverability
- Finish: Armor Black for durability and corrosion resistance
- Ejector: Fixed ejector system for consistent performance
- Brace: Rip brace for enhanced control and stability
What Makes It Stand Out
The Banshee MK4 delivers the ergonomic familiarity of AR-pattern controls with the efficiency of 9mm ammunition. The 8-inch barrel strikes an ideal balance—short enough for close-quarters handling, yet long enough to extract meaningful velocity from 9mm rounds.
The fixed ejector ensures reliable case ejection across various ammunition types, while the included Rip brace provides shooters with improved control and support. Whether you're training, competing, or building a versatile home-defense setup, the Banshee MK4 offers the accuracy and dependability CMMG is known for.
Ideal For
Shooters seeking a compact, AR-platform 9mm with modern ergonomics and proven reliability.
