First, you cannot fix the damage already done but you can repair and stop the rust from doing more damage. Take a fine sandpaper or a wire wheel or steel wool and remove all the rust from the gun. After the rust is removed, reblue the gun with a solution made just for this. Ask any gunshop for the solution you need. If the damage is to the point to make the gun unsafe to use as in holes in the barrel or in the firing mechanisms, you may need to replace the effected parts.

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.
