CMMG Resolute Mk3 | .308 Win | 16.1″ Barrel

The CMMG Resolute Mk3 is a compact .308 Win carbine built on a Gen 1 DPMS high-pattern LR308-style platform for enhanced parts compatibility and customization potential. It pairs carbine-length handling with the ballistics of the .308 Win cartridge, and includes CMMG ZEROED components and the RipStock for ergonomic control. A suitable optic under $1000 to pair with this rifle is the Vortex Viper PST Gen II 1-6×24, which balances low-power zoom for close work and enough clarity for mid-range shots.

Applications: mid-range precision shooting and medium-game hunting.
