The CMMG Resolute Mk4 350 Legend 16.1" rifle in Coyote Tan bridges the gap between full-size hunting rifles and shorter platforms—delivering legitimate long-range performance in a compact, maneuverable package. Built on CMMG's proven Mk4 AR15 platform and chambered in 350 Legend, this carbine is purpose-built for hunters in states with straight-wall cartridge restrictions. The 350 Legend gives you more velocity and energy downrange than classics like the .30-30, while keeping recoil manageable—ideal for deer hunting where precision matters and you need a rifle that doesn't tire you out over a long day afield.
Every component on the Resolute comes from CMMG's ZEROED suite of quality parts, assembled and tested at the factory. The billet aluminum upper receiver, forged lower, and direct impingement gas system deliver reliability you can count on. The EML15 M-LOK handguard strips unnecessary weight while keeping M-LOK slots where they count—3, 6, 9, and 12 o'clock—so you can mount a light, sight, or bipod without guessing. The RipStock gives you a solid, repeatable cheek weld and adjusts through six positions to fit your shooting posture and gear setup.
At 6.1 pounds and 32.5 inches long, this isn't a gun that feels like baggage when you're glassing timber or working through thick cover. The 16.1" barrel with 1:16 twist stabilizes 350 Legend loads reliably, and the CMMG ZEROED muzzle brake manages what little recoil exists. Ambidextrous controls—the charging handle, safety, and sling plate—work equally well for lefties and righties. Ten-round magazine capacity respects state regulations while keeping you in the fight. Whether you're hunting whitetail in a restricted-cartridge state or need a nimble, accurate rifle for mid-range work, the Resolute Mk4 in 350 Legend keeps things simple: pick it up, aim it, and let the rifle do what it was built for.
