CMMG Resolute MK4 9mm | 30 rd | 16.1″ Barrel

The CMMG Resolute MK4 is a carbine-length 9mm rifle that uses a radial delayed blowback upper designed for compatibility with 9mm AR conversion magazines. This model features a 16.1″ barrel and a titanium finish, and it ships with CMMG’s EML 15 handguard and RIPSTOCK. For an optic under $1,000 that pairs well with the Resolute for both close-to-mid range work and competition-style engagement, consider the Vortex Viper PST Gen II 1-6×24.

Applications: range training and pistol-caliber carbine (PCC) competition.
