Abstract: An interchangeable scope lens covers system comprises a pair of lens covers each comprising a lens cover sleeve that is generally shaped like a hollow cylinder having a generally decreasing diameter from a proximal end to a distal end. Near the distal end, a generally annular lens is removably secured by a lens cap. The lenses are therefore easily removed and interchanged as desired by the user to configure the system to respond to changing shooting conditions. Between the pair of lens covers is attached a plurality of elastic cords or similar materials that hold the lens covers tightly against both ends of a scope tube in order to provide a press fit that keeps moisture, debris, etc. from entering the space between the lens covers and the scope lenses. The press fit forms a seal or barrier between the lens covers and the scope.
