A couple of questions:

1. Will the barrel from the former Accutrigger but non-Accustock rifle fit an Accustock action and stock? I have a left-over 7mm-08 barrel I'd like to inmstall on a Model 16 Accustock in .243. So is it a drop-in fit?

2. Will the old style ridged barrel nut work on an Accustock action?
