Always look on our supporters list first to help keep the sight going but most any stock maker can build what you want, though I think you are wanting to keep the stocks dimensions the same as they are now after you modified them. That means the stock on you guns will need to be used as a pattern to make the new stock. Otherwise the new stock you arder will be made from a pattern that will duplicate what was there before your changes! The are many folks with duplicators but 'WENIGS; in Lincoln, Missouri would be my suggestions. I know those guys and they do a great job and are reasonable...
