You can do it.
All you need is a 308 sized .473 bolt head, regular baffle, magazine and follower, go and nogo gages, barrel nut wrench and a barrel or action vise.
Oh and a 220 swift barrel.
The factory barrel nuts are put on by a gorilla, so you may really have to whack it hard to get it off.
Does not have to be that tight going back on. Maybe 30-40 ft/lb or a good whack on the wrench with a hammer
