I only bed my bases if I never plan on removing the scope and bases from the rifle but you can remove them with a little heat. always coat your screws with a release agent and the holes,other wise you with play hell getting them back out if ever. Your barrel nut wrench should fit just fine as long as the bases don't extend over the nut I have seen bases that do.being a switch barrel gun I don't think I would bed the base if it was me, Just make sure the base screws are torqued the proper amount and I like to add a little purple lock tite to the screws.
