All stocks are machined to what I consider to be 90%. You may still need to remove a small amount of wood in order to have your action and fit properly. All stocks will be semi-inletted and unfinished. Stocks will have the channels and openings cut for the barreled action, although each stock may need a minimal amount of filing and fitting for final installation. A small amount of sanding will be needed and your stock will be ready for the finish of your choice. If you are unsure whether you can do the fitting, then it is highly recommended that you contact a local gunsmith to assist you in the fitting of your stock.
