So some of you may remember that my grandfather gifted me a Mossberg US44 (a) rifle a few months ago. I'd say it's in pretty good shape (not that it matters since I'm keeping it no matter what), but I wanted to have a smith look at my barrel for me. Here are two pictures of the pitting on the barrel. I'd like to get it cleaned up if possible. If it's not possible to clean it up with basically sanding down, should I just leave it? I can't imagine it is hurting anything. Here are the pictures.




Also, I think this is the original sight with the several different posts you can use, but I'm not sure. It looks like the sight should have had a hood on it, that is long since gone. The issue with the front sight is that it is on the barrel crooked. I can move the sight around, but can't get it tight into the barrel and have it be centered at the same time. Should that be an easy fix?
