Some users have noted that there can be feeding issues with KA brand M4 magazines but the issue is remedied by slight filing of the mag feeder. I have not experienced any issues myself but a small amount of people have.
filing the top of the round part where the BB goes in you mean? so the mag fit deeper in the magwell?
ok, anyway, I'll order them, we'll see if I have problems with them.
