Search didn't find anything. I'm considering a York Arms lower for my next build because I can get a custom serial number (included in the charge). They are also devoid of a rollmark in the event I want to have a custom image added.

Their site doesn't say from whom they acquire the lowers. It does say they are forged and CNC machined fwiw. If anyone has had experience with them, I'd love to know if they were in spec as far as magazines, LPK installations, etc.

Thanks!
