CMMG Dissent Mk3 8.6 Blackout 12.5" 30+1 Semi-Auto Pistol - Tungsten

The CMMG Dissent Mk3 is a 8.6 Blackout semi-auto pistol purpose-built around CMMG's bufferless operating system, an architecture that trims bulk by eliminating the buffer tube while preserving familiar AR-pattern controls. Chambered for the modern 8.6 BLK cartridge, this Mk3 variant is driven by a 12.5" barrel with an aggressive 1:3 twist that fully stabilizes the heavy subsonic and supersonic projectiles the cartridge was designed around.

The barrel is machined from 4140 chromoly steel with a hard nitride finish, threaded 5/8x24 for suppressor and muzzle-device use, and ships with a CMMG ZEROED Linear Compensator already installed. An adjustable gas block lets you tune cycling with both subsonic and supersonic loads. The lower carries an integrated trigger guard, while the CMMG ZEROED 60/90-degree safety selector gives you a familiar throw pattern. The upper and lower receivers are machined from 7075-T6 aluminum and finished in a hard-wearing Tungsten Cerakote for corrosion resistance and a clean sight picture through mounted optics.

Feeding is handled by Magpul PMAG magazines. CMMG ships this pistol with (2) 20-round PMAGs, and the platform accepts standard 30-round magazines for a true 30+1 capacity in a package weighing roughly 7.3 lbs and stretching about 23" overall. The M-LOK handguard provides a slim accessory platform for lights, lasers, or foregrips without weighing down the front end. Whether you run it as a tactical pistol, a suppressor host, or as the heart of a future SBR project, the Dissent Mk3 8.6 BLK is a current-production CMMG pistol.
