The CMMG RESOLUTE MK4 350 Legend 16.1" Tungsten is a modern AR15-platform rifle purpose-built for the 350 Legend cartridge—a straight-wall round designed for hunting and sport shooting where straight-wall rifle ammunition is mandated by state regulations. Built on the proven Mk4 AR15 platform, this rifle delivers the ergonomic familiarity of the modern carbine while optimizing for the ballistic profile and lower recoil impulse of the 350 Legend round.
The rifle features a full-length EML handguard with M-LOK slots on both sides and underneath, enabling rapid mounting of lights, lasers, and accessories without rail clutter. CMMG's ZEROED parts package includes a drop-in single-stage trigger, ambi safety (60/90 degree), ambi mag catch, ambi charging handle, extended mag release button, bolt catch, and polymer dust cover—components that enable platform-standard maintenance and customization. The threaded muzzle brake facilitates sound suppression or other muzzle device integration. Barrel length of 16.1 inches balances velocity for 350 Legend hunting loads with overall handling length. The rifle ships with one 10-round magazine and weighs 8.4 pounds, making it suitable for extended field use.
This build is purpose-designed for hunters and sport shooters operating in jurisdictions requiring straight-wall rifles. The 350 Legend cartridge delivers effective terminal performance within 200 yards while minimizing over-penetration concerns on smaller game. The Mk4 platform's modularity allows users to convert to other upper receiver configurations or upgrade components as their mission evolves. Operators familiar with AR ergonomics transition immediately to this rifle without relearning controls or manipulations.
The 350 Legend segment has grown steadily among hunting communities in straight-wall-only states and among shooters seeking an AR-platform rifle with minimal recoil for extended target practice. The tungsten finish provides corrosion resistance and a modern aesthetic. Standard AR15 aftermarket stock options, grips, and optic mounts remain compatible, enabling full customization without proprietary dependencies.
