FSC chops

Damn it's been a LONG time since I've been on MCB, even my old account got purged.
But anyway, my First Strike Compact chops paint like nobody's business and I can't figure out what's wrong. I changed paint brands, changed mag springs, clean it thoroughly, adjusting the pressure and nothing helps. What else can I do? Is this a common problem? I get at least 2 chops per mag totally at random.

Worn out ball detent....

Also chops or barrel breaks?

I don't know how the detents would be bad, I haven't put more than a case of paint through the gun. Plus it's had the issue since I bought it and I got it new.
And both, I think. There is paint run down into the mags when I eject them so I assumed it's happening at the bolt.
