Greetings everyone... I am an avid firearms owner however I no longer hunt. I just really enjoy going to the range. I have inherited a 12 gauge shotgun from my late father that was sold by Western Auto back in the 60's and is called a Revelation 510A. After doing some online research I discovered it to be a Mossberg 510A. It is in descent condition and I would like to do some skeet and trap shooting with it, however, the barrel is somewhat pitted. I would like to either re-blue the barrel, or better yet, replace it with a new one. I'm not sure but from what I have read I can use any barrel from the 500 series Mossbergs? This is my first pump shotgun so please excuse my inexperience. Any help would be appreciated.
