.... Perhaps there are three, easier alternatives; use a "scout type mount" that fits in the rear sight base, higher scope rings,and simply remove the "ladder portion" of the rear sight . I would assume that you've already tried simply moving the scope further to the rear ? Even if you do knock the rear sight in it's entirety, loose, it will probably have to be cut to slide over the foresight, unless that's already been removed . .... David K.
