The barrel nut loosened easily, but then was very difficult to unscrew the nut from the barrel-the action came off the barrel easily. There was a lot of solid chips?dirt?filings? in the threads. The nut would NOT go on the replacement barrel. The replacement barrel screws in the action fine. I need a new nut. Midway and Brownells have no nuts with the square notches. Savage has none and won't have any. Gun shack-advertiser here-sold me 2 for $41.75 delivered. This gun is ~2 years old, first barrel removal. This is a first for me, the amount of crap in the threads and the ruined nut.
