Not sure about their sidelocks BPS but they do use it on many of their rifles. Don't know if it's "LocTite" per say but they use some form of the stuff. As far as using a hair drier, it could work. At least some of them put out pretty good heat. Plenty to loosen LocTite enough to be turned out. Heat gun would be better but many don't have them. Most households have a hair drier in them though.
