I just picked up a model 10 which is topped off with a "Mascot 1" sight rib. It looks like it is designed to allow adjustment of the front sight for windage and the rear sight for elevation. I originally thought this sighting rib would allow me to set up some pre sets for various distances but I cant figure out how that would work the way this one is set up.
Does anyone know where I can find a set of instructions for this rib or can anyone provide some more details esp with regard to pre sets??
