CMMG 55A1F0B Resolute FOB 5.56 NATO 11-Round Carbine

The CMMG 55A1F0B Resolute FOB 5.56 NATO 10-round carbine is purpose-built for duty-rated professionals who demand reliability under pressure. Designed as a compact, modular platform, this rifle excels in law enforcement and military applications where space constraints and rapid deployment are mission-critical. The 10-round magazine capacity positions this carbine as an optimal choice for operators requiring a balance between firepower and maneuverability in confined environments—vehicles, buildings, and tactical insertions where full-size rifle lengths become liabilities.

CMMG engineered the Resolute platform around 5.56 NATO standardization, ensuring interoperability with mil-spec ammunition and existing supply chains across agencies and teams. The FOB designation reflects a focus on fighting-rifle ergonomics: refined controls, predictable trigger geometry, and modular rail systems that accept industry-standard tactical accessories. At 8.96 pounds fully configured, this carbine maintains the weight discipline essential for extended operations while the 41-inch overall length preserves the compact profile that defines modern duty rifles.

The aluminum receiver and precision-machined components deliver the mechanical consistency demanded by professional end-users who cannot afford point-of-impact drift or feeding inconsistencies. This platform serves tactical teams, SWAT operators, and military personnel deploying in vehicles or close-quarters environments where traditional rifles may be cumbersome. With its modular design, the Resolute FOB is compatible with a wide range of tactical accessories, enhancing its versatility for various missions.
