I have a Bell and Carlson stock sitting around that I plan to swap several rifles in and out of for various purposes. There is a slight imperfection where the back of the recoil lug would mate up, sort of like an overhanging ridge big enough to see and feel so it might not shoot good. I don't want to bed it to one action because several different actions will sit in it. I need to figure out how to fix that mating surface. There is a machine shop right down the road, in case there aren't any simpler DIY options. Any suggestions?
