Ok so this has now happened to me twice, two different range sessions.  I will be shooting the AR and get a jam.  Look at the round and it has two large gashes in the brass half way up the round.  

Clear the jam, shoot a few more, boom same thing.  

Take out the mage put another one in no problems.

Put another one in, no problem.  Obviously it is a mag problem, but what do you guys think the specific problem would be?  I am using USGI 30 Rounds mags purchased through Bravocompany.  I should probably just get rid of the mag, but if I can salvage it I would like to. Any help would be great.  Thanks

Save the spring follower and base plate and round-file the rest.

Try dressing up the front of the suspect mag with a file. The mags seam there when folded during assembly, might be a bit too high, causing the rounds to drag on the mag body as they enter the chamber.

It also could be your magazine release is to tight/loose.

Quib- Tell the man what Im talking about.................I cant fully explain what it is.



Buy a Pmag. That will fully eliminate the possibility of mag problems. You can get one from AIM for cheap.

I have two of them and will never buy anything but Pmags again.  Not worth the hassle, when Pmags are so damned good.

+1  i have 8 and love them

my GI mags seem to hang on the lip on the edge.  slowly remove rounds out of the mag with your hand and see if you can tell were it might be catching
