Stoney Point manufactures a quality, machined metal target knob that is designed specifically for a particular manufacturer of scope. They run around $30 each for windage and elevation knobs that screw directly to the scope with a matched slot for adjustment and gradient markings for reference. I used them a few years back and eventually sent the scope to the manufactuer for factory adjustment knobs.
