Well PMags are the worst offenders, the other mags are ASC steel mags. The mag well allows almost 1/2 inch of front and back play with either magazine. The lower has other problems as well, the bolt stop is almost impossible to drop the bolt to feed a round , it wont move. Probably pull the CMC trigger out, reinstall the original trigger and send it back to PSA. Even the Mag release button is balky. Worst lower I have ever fooled with bar none.
