.350 LEGEND MAGAZINES FOR AR-15 Reviews & Ratings

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.

Functions but low capacity

I have a CMMG 350 Legend 10 round magazine. It fits well and functions perfectly in a Bushmaster Carbon15 lower with homemade 350 Legend upper using a Faxon barrel. This mag weighs 3.1 oz. on my scale. In comparison, a 20 round Lancer mag weighs 3.5 oz. 3 stars because 350 Legend mags only come in low capacity versions. The 350 Legend is the perfect "pistol caliber" carbine and as such would be great for home defense if standard capacity magazines were available.
