The Williams FP-AG-TK sight is an air gun sight with target knobs but based on several reviews it can also be clamped on top of the 10-22 Weaver TO-9 scope base. Anyone using one of these or the Williams FP-RU-TK model that's designed specifically for the 10-22 and requires d&t to the side of the receiver? It seems like a taller front sight would be required for either one and I'm guessing a lot taller one for the air gun model that might not work so well for close range shots.
