This should help you with the scope base removal…don't be afraid to use a torch to heat it…sometimes its required to get these things off…I've removed quite a few, sometimes a heat gun will get it done but sometimes more resin/glue is used on each rail and its more of a problem.

Chances are from what you described…the previous owner may have added some sort of permanent Lock-tite on the screws, should not be that hard to unscrew from the factory, its usually only an issue breaking the bond when seperating the base from the receiver, screws are never an issue…you may need a torch or a really good heat gun to heat up the screws enough to break or melt that bond…if you are not comfortable or you don't know exactly what you are doing I would get some help from someone who's done it before…or better yet a professional gunsmith.
