CMMG Dissent MK3 8.6 Blackout 12.5" Pistol
CMMG's Dissent MK3 in 8.6 Blackout delivers AR10-class power in a compact 12.5" pistol platform. Features 7075-T6 aluminum receiver, 11" handguard, and optimized 1:3 barrel twist for suppressed performance.
The Modern Intermediate Cartridge Solution
The 8.6 Blackout represents a significant evolution in intermediate cartridge design. Building on the proven foundation of 300 Blackout, this .338-caliber round delivers superior ballistics in a package that performs exceptionally well from shorter barrels—making it ideal for the compact pistol format.
Performance and Design
Barrel and Twist Rate The 12.5" barrel features a quick 1:3 twist rate, specifically optimized for 8.6 Blackout's heavier projectiles. This combination ensures reliable stabilization and consistent accuracy across a wide range of ammunition weights.
Suppression Excellence Like its 300 Blackout predecessor, 8.6 Blackout excels with suppressors. The larger .338 projectiles and efficient case design produce exceptional sound reduction while maintaining the velocity needed for reliable function.
