I just purchased a left handed Model 16 Accustock in .243 Win and would like to also be able to use a 7 mm-08 barrel I already own on it so I'm going to have to be able to switch barrels. Therefore, I have a few questions:

1.This rifle has the new smooth barrel nut so to loosen it I'll need the specific SSS nut wrench made for them. Has anyone had any experience with this wrench and dealing with these smooth nuts? Mine doesn't have the hole some of them do so the wrench will have to rely on friction.

2. I was told the smooth nut can be removed with a pipe wrench, which certainly damages them, and then replaced with the older style grooved nut which then uses the older style nut wrench. Comments? Does the older nut fit in the Accustock?

3. Any other specific differences I should know about?

Thanks.
