there is additional adjustment using the " V " or aperture. Loosen the two tiny screws that hold the v on and go up or down slightly if one notch of the elevator is too high and the next notch is too low. a little humbug but it works. Is the v missing? the base has a rough stamped v that the aperture fits onto but it needs the v aperture installed. Most win. M94's have this style sight. Mel
