Cmmg, Resolute Fob, 223 Rem 5.56 Nato, 10+1, Nitride Barrel, Ambidextrous

The CMMG 55A1F0B Resolute FOB 223 Rem/5.56 NATO brings the Resolute series' reliability to the AR-15 platform with a 10+1 capacity and a black nitride barrel built for corrosion resistance and sustained accuracy, making it well suited for range work, varmint hunting, or duty use. You'll notice the full-length Picatinny rail receiver for optics and backup sights, and ergonomics are handled by B5 Systems components – the P-Grip 22 with grip plug and Bravo stock deliver familiar control behind a Mil-Spec single-stage trigger for consistent pull. This model is ambidextrous by design: a ZEROED 60/90� ambi safety, ZEROED bolt catch, and ZEROED ambi mag catch/release let left- and right-handed shooters operate smoothly during transitions and manipulations. The package includes a ZEROED muzzle brake to tame recoil and a ZEROED polymer dust cover to protect internals in field conditions. As an AR-style semi-auto rifle chambered in 223 Rem/5.56 NATO, it requires an FFL transfer and is built to accept common AR accessories and optics, making the Resolute AOB an adaptable choice for shooters who want a serviceable, modular rifle suited to training, home defense, competition stages, and hunting scenarios.
