I have a JC Higgins 12ga auto model 60. I am trying to replace the action bar.
It appears fairly simple but I am unable to figure how to get the barrel off or does the magazine tube come off instead. Any help would be appreciated.
The barrel is thread into the receiver and it is tighten tight. I tried a barrel vise and made a special wrench for the receiver. I could not get it to budge. I quit before I twisted the receiver. Years ago when I re-blued it, I'm thinking I saw a retainer nut used to lock the barrel to the receiver inside the receiver. I maybe wrong, I could never find a schematic that showed such a retainer and I just look again all my books when I saw your post. They may have tighten them like the 1917 Enfields which I have gotten apart. Anyhow, Why do you need to separate the barrel from the receiver?
