If you let me see that action once I can solve the barrel nut problem for you. And the tags aren't something that only we can use. I tell folks all the time that if you want to give it to another gunsmith in the future have at it. If they say they can't work with the information that's on the tag though, be very careful about giving them the work...I have some great actions that are older and not "pre fit" ready - barrel nut remage barrels work great and keep those older actions viable.
