Hey guys....
I'm currently trying to change out an A2 upper for a flat-top. The only problem is, I cannot seem to get the gas tube roll pin out of the FSB. The pin looks almost as if it's peened over on both sides of the FSB.
Any ideas? Would it work to very carefully drill the pin out, and just replace it?
