How do you remove barrel on high standard supermatic shotgun? - Answers

To remove barrel, first disassemble gun. Remove magazine by inserting a 1/4" dia punch in the hole in the magazine and unscrew. Now the hard part. Unscrew the action from the barrel. You will need a special barrel vice and a special action wrench to do this - if you don't want to bugger up the barrel and action. The barrel vice needs to accomodate the rib (if installed). It needs to use custom made wooden jaws (for each different barrel). Use rosin on wooden jaws to increase friction. These tools are usually only economical to make if you are in the gun repair business.
