NIKON Switchview BLACK 30mm Throw Lever (16418)

Nikon Switchview Black 30mm Throw Lever (16418) enables quick and easy adjustment of a scope's power setting with a simple push or pull of the lever. Simply clamp it around the zoom ring of a variable power scope, and the extended arm gives the proper leverage to turn a stiff power selector ring, or to rapidly move from high to low power and vice versa.
