I'm glad someone has had a good PTAC, hopefully that's a sign there improving.I have a PTAC upper on a polymer rifle and I have been real happy with it. I have been feeding it nothing but steel case Tulammo for almost six years now and it's never had a hiccup. That being said, I think buying from PSA is a little bit like playing roulette. I have gotten some awesome products and some that we also garbage. It's been a mixed bag and I have heard plenty of horror stories.
