APO Objective Lens System - Corrects color across the entire visual color spectrum-virtually eliminating chromatic aberration across the entire field of view
35 mm Tube - Provides more internal room to accommodate a greater range of windage and elevation adjustment to accurately dial longer-range shots
RZR Zero Stop - Rapid Zero Return RZR feature stops the turret from dialing below sight in range using rugged steel components Internal mechanisms stay free of sand dirt dust moisture and other foreign materials-even when setting the zero-stop position
First Focal Plane Reticle - Scale of reticle remains in proportion to the zoomed image Constant subtensions allow accurate holdover and ranging at all magnifications-no shift in point of impact during zoom
Erector Tube System - Precision-machined from premium brass alloy with anti-galling properties for great strength and durability The erector spring of chromium vanadium withstands compression has high fatigue resistance and is tumble-polished to a mirror finish for micro-precise elevation and windage adjustments
