What rings do I need for the Bushnell Banner 3-9×40? The Bushnell Banner 3-9×40 uses standard 1-inch diameter scope rings. Scopes Field
Set your scope magnification to its highest power (9x) and mount the scope loosely in its rings. Slide the scope forward or backward until you see a full field of view without any black "halos" or "donuts" around the edges.
A scope is only as good as its mount.
