It is not very hard to learn how to do it but it requires a few tools (a one time buy under $100) a little 'mechanical savvy' and sound advice/instructions ( especially for the first time). The stock is non-essential since, as Boiler said, you would remove the action from your stock any time you do the swap. You save a bunch of money this route and there is the pride of doing it yourself. One of the beauties of this approach (for me at least) is that you can find a stock/action/scope platform you like and then by simply switching the barrel you can have a different rifle (depending on what caliber you want you may need a small bolt head modification as well). I would do it again in a heart beat. And another thing, I have done my first build only after 6 month of shooting while a novice.
