Poorly built upper reciever lr308 dpms - TacFire DPMS .308 Winchester Complete Upper Assembly

I recently bought the (DPMS) LR 308 upper reciever from tacfire. The item had fast shipping and when I opened the package it looked like a decent quality full upper for the money. So I got a headspacing guage set and tested them out on there product. So with the "NoGo" guage the BCG would not close all the way like it should. So then I tried the "Go" guage, which is supposed to fully close but it didn't.so I knew somthing was wrong. So I ordered a different barrel and put that on and was still having the same issue. So I brought the upper to a gun smith they looked at it and said it is the upper reciever that was out of spec. So I got a different upper stripped reciever put everything back together and it worked. You may or may not run into this particular issue like me, but I don't recommend buying this upper. And Optics planet will return but they charge you a return fee and percentage for restocking fee.
