Ah, I see, thanks.
I guess my gun must be defective then because it does that with the factory mags. You think they would have caught that when they test fired it after repairing it.
Anyway, I already told him to steer clear of the ATI stock becuase it will bend the pins. I know it did mine. Not to mention my misfeeding problems. But he likes the TS stock better anyway. So that parts all good. I just didnt want him rushing out to do something without having all the info and I didnt have it.
