Sorry for all the trouble. While the pad was not glued on by the factory, it is possible that someone along the way glued it on. To remove glued on pads you will need to replace the pad as it won't survive the removal process. First tape the butt stock finish with masking tape to prevent little scratches. Using a chisel and hammer remove the pad by cutting the plastic base of the pad. Lay the stock on the side, on some old rags on the bench, put the chisel edge against the center of this layer of plastic. Don't try splitting it away from the wood as the wood will crush and the damage will show in the junction of the new pad and the stock. When the old pad ismostly gone scrape away as much as possible, avoiding damage to the edge of the butt. Lightly sand the butt of the stock, a belt sander is best, to level the mounting area for the new pad. The new pad is then mounted as usual. This is just another of the joys of mounting recoil pads.. Be sure to coat the end grain of the stock, if it is not already.. Good luck.
