I talked to my Marine buddy... and he still hasn't gotten me an AR mag. If he can't put his hands on one... I'll just go buy one this weekend. I know the local gun shop has them for about $20. I'll also pick up a Mini-14 mag... but that one may not be as easy.

For the guys who may know... Did the other people trying to use an AR mag say why it wouldn't work? I know it's not a center feed... but it should still pop the round out toward the center.
