Get your gun on target faster and use less ammunition doing it. These targets use patent-pending technology to tell you the exact number of windage and elevation adjustment clicks your scope needs to put your bullet in the bull’s-eye. The system works with scopes using 1/8-, 1/4- and 1/2-MOA click adjustment, and it’s effective for zeroing in at 25, 50 or 100 yards. Per 10. Size: 12" x 12"
