Star Mags have introduced a new line of AR-15 magazines made in Montana. They have a new high capacity mag of 41 rounds for the .223 / 5.56 as well as a 30 round and a 10 round magazine. What is unique about these mags is the star emblem on the 30 and 41 round mags that is a clear polymer that allows you to see the rounds inside the magazine body. The 10 round has the stars, but they are not clear. These black polymer mags have a blue anti-tilt follower. Check out these and other AR-15 magazines at The Country Shed.
