You need to find some one with a buffing machine to get that out. A few strokes over a buffing wheel and that will disappear. If you have a grinder you can get a cloth wheel and some rouge for it. Take the guard off the grinder and buff away.
I need to do the same thing to my old original 1970 Rem 870.
Would you possibly be kind enough to do an eBay or Amazon search and provide me with links for some specific polishing wheels and rouge to use on my grinder to get the minor pits out?

Hit it with oil and fine steel wool to remove the rust.
After a thorough de-greasing, pits are best hit with waterproof bearing grease before wiping down the general surface with a clean, dry cloth to remove most of the excess. The grease will remain in the pits. Then, oil the firearm normally.
