CMMG Dissent Mk4 338arc 10-Round Pistol

The CMMG Dissent Mk4 in 338 ARC is a purpose-built semi-automatic pistol engineered for shooters seeking precision performance in an efficient, compact platform. Chambered in 338 ARC—a modern intermediate cartridge optimized for barrel lengths between 6 and 7 inches—this pistol delivers superior ballistic efficiency compared to standard intermediate rounds across a range of tactical and sporting applications. The 6.5-inch barrel maximizes velocity development while maintaining a controllable form factor suitable for both bench work and dynamic shooting disciplines.

This configuration ships with a single 10-round magazine and a durable Cerakote finish applied in black, offering corrosion resistance critical for extended field storage and varied environmental conditions. The 338 ARC cartridge itself represents a meaningful step forward in intermediate-range precision: it delivers flatter trajectories and superior long-range energy retention than 300 Blackout while operating within standard 308-Winchester case dimensions, ensuring component availability and reload compatibility. The pistol's architecture supports the platform's reputation for accuracy and component modularity, key factors for operators who plan future customization or accessory integration.

The Dissent Mk4 appeals to precision-focused shooters, defensive professionals evaluating non-NFA alternatives to short-barreled rifles, and competitive shooters competing in modern shooting sports. Those seeking a 338 ARC pistol for precision rifle-caliber ballistics in a portable package will find this platform's barrel length and caliber pairing optimized for target engagement beyond 200 yards. The inclusion of a single 10-round magazine provides baseline capacity while remaining compatible with broader CMMG platform ecosystems. No arm brace is included with this configuration, leaving the end user to select mounting solutions aligned with their intended application and regulatory environment.
