FSB canted to the right. Had the same issue on a ballistic advantage 14.5 mid length I bought elsewhere. I’m going to pass on these in the future. If my OCD allowed me to live with a canted FSB, I’d just own an AK.
I just wish in both cases I would have had a chance to inspect them before a week and the return/exchange window was up.
