I'm looking at a used 7600 that has some light surface rust on the bottom of the receiver. What would be the best way to remove the rust? Would rebluing it after the rust is removed make it unnoticeable? What is a ballpark figure to have one reblued?
If its light, no pits, you can remove it with 4 ought steel wool and cutting oil. Light strokes, don't scrub in one spot, and the bluing will not be affected.
If the rust is already below the surface, polish and reblue is the answer. That gun can be professionally reblued for $100 just about anywhere, but choose a well known shop.
Too heavy on the polishing wheel will cause unreversable swales in the metal.
That's an easy one, most of the damage is on the clip.
Try the 4/0 wool, wont hurt. You can buy a NOS clip for $29, I would not waste a lot of effort on it. Clean that old clip best you can and keep it for a spare, no deer will ever know it was rusty! LOL!
