I went the route of the Non-Accustock. Owned two and was not impressed. You get the smooth barrel nut that you either have to get a special tool to remove the nut or use a pipe wrench and replace the nut. The barrel lug I don't think can be changed out in an accustock. I took my model 16 and sold the barrel and stock and built my 7mm-08 from there. I paid $473 for a non accustock version. You buy accustock you are paying extra from the get go. Also if you go accustock there's a very good chance you will have the bottom bolt release which in my opinion is not a good option.
