CMMG Dissent MK4 338 ARC 10.50" 10+1 Semi-Auto Pistol

The CMMG Dissent MK4 is a compact semi-auto pistol chambered in the modern .338 ARC cartridge, blending AR-15-pattern ergonomics with CMMG's redesigned compact operating system. Built around a 10.50" threaded barrel finished in Black Nitride and wrapped in a 9.60" M-LOK handguard, this pistol puts serious downrange performance into a remarkably short package.

The upper and lower receivers are machined from aluminum and finished in Black Armor Cerakote, with an integrated Picatinny rail up top for optic mounting and a rear Picatinny rail for accessories or backup iron sights. The CMMG Zeroed 60/90 Degree ambidextrous safety gives the shooter configurable lever throw, while the CMMG Zeroed pistol grip offers an ergonomic, secure hold in a black polymer housing. No sights are included, leaving the optic choice to the end user.

Chambered for .338 ARC with a stated 10+1 capacity, the Dissent MK4 measures just 18.70" overall and tips the scales at 4.90 lbs. This is a feature-rich, optics-ready compact pistol built for shooters who want .338 ARC performance in an AR-15-pattern platform.
