Thread: Dark Arts of Magazine Manipulation

Looks like the feed lips are too wide at the front. If this was happening with a pistol mag my fix would be to squeeze up the front of the lips a little until the body of the shell cant slip out between them. If this mags feed lips are a slip on "over the top of" the polymer mag body type then i dont know how successful you will be with squeezing them together and getting it to stay that way for any length of time, it might require touching up often depnding on how much use it gets.

Chuck it in a vice and give it a go, just a little at a time, too tight and you will get feeding issues as well. And test with a full mag.
