When ordering from Shaw you need to call them to place an order and they will ask you exactly what you want done including what action you have and they will thread it for the action. I suggest you go to the website and look at their pricing list and write down what you want down before calling. It usually takes a gunsmith to remove the old barrel, install and head space the new barrel. My local gunsmith charges $150.00 for any of the Savage, Ruger, Remlin, etc and $200.00 for Mauser etc., and a little more if the stock needs to be worked on. I have a few of their barrels and they have all been excellent shooters.
