Personally, after proper cleaning and degreassing, I use epoxy to secure the bases and Blue Loctite for the mounting screws (the bond is not too strong).
Pay attention not to epoxy the screws !
Why epoxy the bases ? Simple, with heavy scope, powerfull caliber, I don't quite trust these small screws that are secured with just a few threads.
To dismout is very easy. You just remove the base screws and with a hot air gun used to strip paint, you heat the bases and snap them off with a rubber hammer.
I fail to understand why Rem, Win and the like don't provide dovetail for scope mounting, like Sako, Tikka, Ruger, Blaser etc.
