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

The CMMG 55A938FAB Dissent chambered in 5.56x45mm NATO is a short-barreled rifle engineered for shooters who prioritize maneuverability without compromising velocity or reliability. With its compact 6.50" barrel, black Cerakote receiver finish, and 30+1 round capacity, the Dissent delivers the ballistic efficiency of the 5.56 cartridge in a platform optimized for close-quarters environments, patrol duty, and dynamic range work. The zeroed drop-in single-stage trigger provides predictable break and fast follow-up shots—critical advantages in high-stress scenarios where split-second accuracy determines performance.

The 6.50" barrel length maintains practical 5.56 NATO velocity while keeping overall rifle length compact—approximately 39.6 inches total. The Cerakote receiver provides enhanced corrosion resistance without adding measurable weight, critical for operators working in variable environments. The OEM grip ensures ergonomic consistency across platforms, while the Picatinny buffer adapter supports modern AR-platform accessories and modularity. At 9.6 pounds, the rifle balances controllability with the heft necessary for recoil management during rapid fire strings. The factory-zeroed trigger reduces the need for costly post-purchase gunsmithing and allows immediate deployment.

The CMMG Dissent serves law enforcement operators, military personnel, and civilian shooters operating in constrained spaces where longer rifles become a liability. Urban patrol, vehicle platforms, and tactical courses where quick target transitions are essential all favor this platform's compact dimensions and reliability track record. The 5.56 cartridge remains the NATO standard, ensuring ammunition interoperability and widespread availability. This configuration appeals to shooters who've tested longer barrels and found them impractical for their operational reality.
