OK, I want to give my nephew's future wife some AR magazines for Christmas. I wanted the C products ones off the Aim Surplus website, but they sold out. C Products AR15/M16 30rd .223/5.56 Mag w/ Anti-tilt follower Black Finish I should've gone ahead and ordered when a fellow forumite posted that link a month ago, D'oh! On another website, i found two similar options from C products: aluminum 30 round 30 round aluminum magazine with orange follower and steel 30 round 20 round stainless steel magazine with orange follower . Which would an AR chick want? I notice the steel one is marked "EMC" for some mag-retention feature i saw mentioned. I know she wants it in black & 5.56/.223, but i'm not sure if she would rather have steel or aluminum. I would think steel, but i don't have an AR and am wondering if there is something favored about aluminum magazines. She did go through basic training for the National Guard, i believe, but i haven't heard "mil spec" mentioned. Lil hep please.
