CMMG Banshee MK4 5.56 NATO 10.5" Barrel AR Pistol - Black

The CMMG Banshee MK4 delivers compact firepower in a precision-engineered AR platform optimized for close-quarters applications. This 5.56 NATO chambered pistol combines CMMG's proven manufacturing standards with a 10.5-inch barrel configuration that maximizes maneuverability without sacrificing terminal performance.

What Makes This Different

The Banshee MK4 features CMMG's proprietary Ripstock buffer tube system, eliminating the need for traditional pistol braces while maintaining legal compliance. Unlike standard AR pistols that require additional stabilizing accessories, this design integrates a streamlined buffer tube that serves dual purposes as both functional component and ergonomic enhancement. The 10.5-inch barrel length represents the optimal balance between velocity retention and compact handling characteristics.

Key Features

• 10.5-inch 4140 chrome moly steel barrel with 1:7 twist rate for optimal bullet stabilization
• Mil-spec upper and lower receivers machined from 7075-T6 aluminum forgings
• CMMG Ripstock buffer tube system for enhanced ergonomics and legal compliance
• Standard AR-15 magazine compatibility accepts all STANAG pattern magazines
• M-LOK compatible handguard with full-length top rail for optics mounting
• Single-stage mil-spec trigger group with standard AR-15 fire control components
• Ambidextrous safety selector for enhanced manipulation speed

Field performance testing demonstrates consistent sub-2 MOA accuracy with quality ammunition at 100 yards. The 10.5-inch barrel configuration maintains sufficient velocity for effective terminal performance while reducing overall weapon length to 26.5 inches. Weather-resistant finishes and corrosion-resistant materials ensure reliable function across temperature extremes and humidity conditions. Law enforcement agencies have adopted similar configurations for vehicle-based operations and close-quarters tactical applications.
