The CMMG Resolute MK4 in 350 Legend delivers straight-wall cartridge performance in a familiar AR-15 platform. This 16.1-inch barreled rifle combines the stopping power of 350 Legend with CMMG's proven engineering for hunters and shooters in straight-wall cartridge zones.
What Makes This Different
Unlike traditional AR-15s chambered in .223/5.56, the Resolute MK4 handles the larger 350 Legend cartridge through CMMG's modified bolt and barrel extension system. The straight-wall design meets hunting regulations in restricted zones while delivering superior terminal performance compared to pistol cartridges. CMMG's Radial Delayed Blowback system ensures reliable cycling with this larger cartridge.Key Features
