Replacement Stock
Look to McMillan or H-S Precision. You will need a gunsmith to properly bed the barreled action to the stock you choose. You will help yourself alot if you find a local gunsmith to guide you as if you're going to spend the money on a good replacement stock you want the length of pull to fit you well. This will make you a better shooter. Beware of the cheap replacements stocks as most are made of injection molded plastic resins.
