Eyebox design with a huge ocular provides 4" of constant eye relief without sacrificing your field of view. Smooth zoom control with magnification reference numbers viewable from the shooting position, making adjustments in the field quick and precise. Rugged, one-piece, 1" main body tube is oxygen-purged, nitrogen-filled, and O-ring-sealed for 100% waterproof and fogproof protection.
