I bought a mauser 98, the bases on it are #26 rear and #20 front and look mismatched. The catalogues call for #45 rear and #46 front. I tried Leupold bases but the holes are farther apart on the front base so don't match up with the screw holes! Does anyone know if the 26 and 20 bases work on a 98? A search hasn't come up with any answers. Thanks in advance for help on this.
