Legendary CMMG Quality for the New 350 Cartridge

CMMG makes some of the best components for the AR-15 on the market.  This barrel for the new .350 Legend cartridge is no exception.   With a 16 inch length, with a durable salt bath nitride finish, this barrel serves as a solid beginning to a perfect hunting-focused build for your AR-15.  This isn’t a heavyweight barrel either – you’ll be able to take full advantage of the .350 Legend’s mild recoil impulse, with a rifle that isn’t going to weigh you down excessively in the field.

Cross-Compatible Parts

One of the best features of the 350 Legend is that it doesn’t require too many special components.  You use a standard 5.56 bolt carrier group, .750″ gas block, and Carbine gas tube.  For better reliability with the straight-walled 350 Legend cartridge, make sure to use a magazine specific for the caliber.

Since the projectiles in .350 Legend are similar to 9mm, choose a 9mm muzzle device that’s threaded for 1/2×28.
