The lower settings are for extreme low light, and will not be visible in daylight.

What is the tube size for rings on the 3-12x56? 

Asked by: Madsamoan26
Brochure on the Fullfield IV 3-12x56 is a bit confusing as it says 'Main Tube Size: 1 in.,  but then mentions ' 30mm tube offers more adjustment range'. So Burris may want to update the brochure for this specific scope so both references to tube size say 30mm.
