So even though Ive built 7-8 AR rifles sometimes this process is humbling. I just bought a 18 inch premium barrel. Barrel arrived today and looks very nice. Did a once over and wiped packing cosmoline from barrel. After lapping my upper I placed barrel in the receiver checking fitment. Everything appeared GTG until I tried to tighten barrel nut. The barrel nut would tighten until it contacted the barrel index pin. Tried another barrel nut and no go. Checked height of index pin on the barrel and its about .015 higher than previous barrel. From barrel extension measures .115-.116
So.. Ive had issues with the manufacturer before and was hesitant buying another barrel from them. Can you file the index pin or is there anything I can do? This was the last barrel in stock!
Thank you
