CMMG 33A590C-AB Resolute MK3 | 8.6 Blackout | 16.1″

The CMMG Resolute MK3 is a purpose-built carbine-length rifle chambered in 8.6 Blackout with a 16.1″ barrel and a 20-round detachable magazine. It pairs a 7075-T6 aluminum receiver with a 15″ M-LOK handguard and CMMG’s RipStock to deliver a compact, customizable platform for shooters who want more rifle with less overall length. For an optic under $1,000 that balances close- to mid-range capability and durability, consider a Vortex Viper PST Gen II 1-6×24 or a similar low-power variable optic suited to this configuration.

This rifle is appropriate for suppressed hunting and medium-range precision shooting, offering a shorter profile while maintaining the ballistics of larger cartridges when configured correctly. The Resolute MK3 comes equipped with CMMG ZEROED parts, including a Zeroed drop-in single-stage trigger and a Zeroed muzzle brake, to reduce the parts selection burden and simplify initial setup.
