I just bought a Victory 22 today, got it home and tried the takedown. No way that takedown screw would turn. Squirted some Kano Kroil around the screw and waited. Ten minutes later used the supplied hex wrench and gave it some muscle and the screw turned after a little pop. I did notice some dark residue on the screw so maybe SW is applying some loctite at the factory? Will go the O ring route to make sure the screw doesn't work out during shooting.
