CMMG 55A938FAB Dissent 5.56 NATO 6.5" 31-Round Cerakote Rifle

The CMMG 55A938FAB Dissent 5.56 NATO rifle is purpose-built for operators and civilians who demand a compact, modern fighting platform without compromise. At 13.5 inches in overall length with a 6.5-inch barrel, this short-barreled rifle (SBR) delivers the maneuverability of a carbine in confined spaces—vehicle entries, home defense, or close-quarters engagements—while maintaining full-power 5.56 NATO ballistics. The 31-round capacity and Cerakote finish speak to durability and field readiness in professional and civilian tactical applications.

CMMG's Dissent platform integrates a short-stroke piston system that reduces fouling and extends reliability in adverse conditions—a proven design lineage from military and law enforcement adoption. The 6.5-inch barrel generates sufficient velocity for barrier penetration and terminal performance out to 200 yards in defensive scenarios, while the compact profile minimizes weight at 9.6 pounds for extended carry. Cerakote ceramic coating provides corrosion resistance and rugged aesthetics; the 31-round magazine capacity maximizes tactical flexibility without sacrificing ergonomics. This configuration is NFA-regulated as an SBR and requires proper Federal Firearms License (FFL) transfer and legal compliance in your jurisdiction.

Law enforcement tactical units, military contractors, and prepared civilians benefit most from the CMMG Dissent's balance of performance and practicality. The rifle's modularity supports aftermarket rails, optics mounts, and suppressors via the threaded muzzle, enabling customization for role-specific missions. Proper FFL transfer is mandatory; verify SBR registration and local NFA compliance before purchase. The platform accepts standard AR-pattern furniture and magazines, easing logistics and operator familiarity in multi-rifle environments.
