Looking to see if anyone in or around the Laramie area has a Remage or Savage barrel nut wrench. I’d be happy to buy, rent, or borrow for about an hour.
There are a couple of other folks who make them with 1-1/4" flats as well. When using these style, all you have to do is get a 1-1/4" crows foot for a 1/2" drive and it is so much easier to get the proper torque. It is much easier to remove later as well as you can use a regular breaker bar.
