The simplest in tools is the barloc, you basically don’t need a barrel vise or action wrench with that but you need to follow directions as some have had impact shift if the whack the barrel.
Specialized tools will be action wrench and barrel vise, generally I would assume you have decent torque wrenches or bits (barrel is up around 35-100 ft-lbs, various actions screws and scope stuff is in the 15-65 in-lbs range). Then a go/no-go headspace gauge for your caliber is usually a good idea (needed for Barrel nut, good idea but not necessary for shouldered prefits just to be safe).There may be more things depending on the specific action but all of those items will be useful for anything you build.
