Hello,
I've had a 10 BA stealth chambered in .308 for a number of years now. Since I first got the rifle if I loaded more than 5 rounds in the mag it would fall out of the weapon when fired (yes I'm sure it was seated I am an experienced shooter). With the stock mag the bolt would skip over the next round 90% of the time. I got some MagPull PMags and they seem to do better but still it seems like 80% of the time with over 5 rounds the mag will fall out upon firing. The spring on the mag catch seems weak to me. It is not broken but with as small a latching nub as is on these mags then there is some play, I think that is the issue. Has anyone else had this problem? Any ideas on solutions? I haven't been able to locate the spring anywhere online (maybe searching the wrong term). I was considering grinding a little gap below the locking nub on the mags so the latch seats a little further in. Any suggestions would be appreciated.
