I tell people that the fore end has about ten times as much fitting as the butt stock. You have metal coming in three directions, a long area of barrel to fit properly, ejectors and fore end metal tang and the fun areas of release to deal with. The outside is fairly simple to deal with compared to the inside. This explains why 95% of the restocked old guns just got a butt stock and not a matching fore end. Too much work to do unless you have a Dam---- good reason to do it. Nice job by the way but looks like your double is deformed by 90 degrees.
