Last night, I won a Horton Vari-Range Variable Power Lighted Reticle Crossbow Scope. Anybody here have any experience with this glass? This is the model with red and green lights, on 5 cross hairs that adjust according to your arrow speed. I have a Horton with the multi range 4x, unlighted scope. I wonder if i should replace my old glass, which works fine, or sell this new boxed up up wonder.
