I have a Mossberg 590 shotgun with the extended 7 round magazine. Other than it needing a good cleaning, I was wondering if any of the action parts should be polished or de-burred to enhance the functionality of the firearm. Perhaps using 600 grit wet-dry paper on the bolt carrier sides or the action arms?
I can't think of an article or newsthread that discussed doing such a thing. Is it a dumb idea or just not normally done? Should I just keep it clean and leave it at that?
Thanks.
