CMMG® led the way in AR-based innovation surrounding the hot, new 350 Legend cartridge designed for the AR-15, and that led the company to develop the first magazines on the market designed to reliably feed the new round in any standard AR-15 magwell. Each CMMG® 350 Legend AR-15 magazine are made with a stainless-steel body treated with an all-black finish. Inside the magazine, users will find an anti-tilt follower that enhances feeding. The magazines weigh 3.2 ounces and are available in 5-round, 10-round and 20-round capacities.
