CMMG Dissent MK4 300 Blackout 10.5" Pistol - Tungsten Finish

The CMMG Dissent MK4 represents a significant advancement in compact 300 Blackout platforms, delivering rifle-level performance in a pistol configuration. This 10.5-inch barreled system maximizes the ballistic potential of 300 BLK cartridges while maintaining exceptional maneuverability.

What Makes This Different

Unlike traditional AR-15 pistols, the Dissent MK4 incorporates CMMG's radial delayed blowback operating system, eliminating the need for a buffer tube assembly. This design reduces overall length by approximately 7 inches compared to direct impingement systems while providing smoother cycling with both supersonic and subsonic ammunition. The tungsten Cerakote finish offers superior corrosion resistance compared to standard phosphate coatings.

Key Features

• Radial delayed blowback system eliminates buffer tube requirement
• 10.5-inch 4140 chrome moly barrel optimized for 300 Blackout ballistics
• Tungsten Cerakote finish provides enhanced durability and wear resistance
• M-LOK compatible handguard with multiple attachment points
• Ambidextrous charging handle for left and right-handed operation
• SB Tactical SBA3 pistol brace with adjustable length of pull
• Standard AR-15 trigger compatibility and magazine compatibility

The 10.5-inch barrel length represents the optimal balance for 300 Blackout ammunition, achieving complete powder burn while maintaining compact dimensions. This configuration excels in close-quarters applications, vehicle operations, and suppressed shooting scenarios. The radial delayed system cycles reliably with ammunition weights from 110 to 220 grains, making it suitable for both hunting applications and tactical use.
