I have a couple ARs, but doing my first build from scratch. Just about everything is complete now. The problem I am having is the bolt doesn't seem to rotate enough to come free of the barrel. It comes free if I mortar it, but pulling the charging handle alone isn't enough to free it. Everything is well lubed. Carrier comes back about a quarter inch when I pull on the charging handle, but then the bolt catches the inside of the feed ramps. Please help!!
