So, I've heard various things. The gunsmith I have an apprenticeship with says it's ok to lap the bolt, yet what I've read online in forums say not to lap the bolt due to the floating bolt head design. I have my 10 FCP-SR, mentioned in other threads, and although it isn't a major issue, the bolt isn't the smoothest thing in the world. Would lapping the lug grooves in the action slick it up at all or would that just be time wasted?
