Description
The CMMG Resolute MK4 in .350 Legend is built for hunters and range shooters who want the stopping power of a straight-walled cartridge in a familiar AR-platform package — particularly useful in states that restrict hunting to straight-walled centerfire rifle cartridges. .350 Legend delivers meaningful energy at practical hunting distances with noticeably less felt recoil than larger straight-walled options, which makes it a reasonable choice for newer shooters or anyone who runs a high round count at the range.
The 1:16″ twist rate is deliberately slow. .350 Legend projectiles are large in diameter but relatively short for their caliber, and a slower twist stabilizes that bullet geometry more reliably than the faster rates common on 5.56 uppers. If you plan to handload or experiment with ammunition, stick to projectiles in the weight ranges that rate was engineered for — heavier, longer bullets may not stabilize correctly.
CMMG built the Resolute on their MK4 lower, which uses a standard AR-15 fire control group and accepts standard AR-15 compatible components, keeping the platform familiar and parts accessible. The rifle ships without sights, so budget for an optic at purchase — a low-power variable or a red dot both suit the cartridge’s effective range envelope well. The Midnight Bronze Cerakote finish provides corrosion resistance appropriate for field use without requiring the kind of maintenance a blued or parkerized surface would.
