CMMG Banshee MK4 9mm 5" Pistol - Armor Black Finish

The CMMG Banshee MK4 9mm delivers compact firepower with full-size reliability in a 5-inch barrel configuration. This pistol-caliber carbine platform combines CMMG's proven engineering with enhanced ergonomics for superior control and accuracy.

What Makes This Different

Built on CMMG's MK4 lower receiver platform, the Banshee incorporates radial delayed blowback operation that reduces felt recoil by 50% compared to straight blowback systems. The 5-inch barrel provides optimal velocity for 9mm ammunition while maintaining compact dimensions. CMMG's proprietary RDB system eliminates the heavy bolt bounce common in traditional pistol-caliber carbines, resulting in faster follow-up shots and improved accuracy.

Key Features

• Radial delayed blowback system reduces recoil and improves reliability
• 5-inch 4140 chrome moly steel barrel with 1:10 twist rate
• Armor Black Cerakote finish provides superior corrosion resistance
• M-LOK compatible handguard for accessory mounting
• Compatible with Glock-pattern magazines
• SB Tactical pistol stabilizing brace included
• Ambidextrous safety selector and magazine release

The Banshee MK4 excels in close-quarters applications where maneuverability matters most. Law enforcement professionals appreciate the reduced over-penetration risk of 9mm ammunition combined with rifle-like handling characteristics. The radial delayed blowback system cycles reliably with both subsonic and standard pressure ammunition, making it suppressor-ready out of the box. Accuracy testing shows consistent 2-3 MOA performance with quality ammunition at 50 yards.
