CMMG Banshee MkGs 300 Blackout 8" Pistol with SB Tactical Brace

The CMMG Banshee MkGs 300 Blackout delivers compact firepower in a pistol-format platform engineered for versatility and reliability. This radial delayed blowback system operates without a traditional gas system, reducing weight while maintaining consistent cycling across subsonic and supersonic ammunition.

What Makes This Different

The Banshee MkGs utilizes CMMG's proven radial delayed blowback operating system instead of direct impingement or piston operation. This design eliminates the need for a gas block and tube, creating a cleaner-running firearm with reduced fouling in the action. The system cycles reliably with both subsonic and supersonic 300 Blackout loads, making it ideal for suppressed or unsuppressed use.

Key Features

• Radial delayed blowback operation for consistent cycling with all 300 BLK loads
• 8-inch 4140 chrome moly barrel with 1:7 twist rate optimized for heavy bullets
• SB Tactical pistol stabilizing brace in Coyote Tan finish
• CMMG RipBrace interface system for secure brace attachment
• Ambidextrous safety selector and magazine release
• M-LOK compatible handguard for accessory mounting
• Compatible with standard AR-15 triggers and furniture

The 300 Blackout chambering excels in close-quarters applications where compact size and stopping power matter most. Law enforcement and civilian users appreciate the platform's ability to deliver rifle-caliber performance from a pistol-length package. The radial delayed system runs cleaner than direct impingement designs, requiring less maintenance during extended use.
