VX-3i brings legendary Leupold Gold Ring performance to a new level. Twilight Max Light Management System provides maximum brightness in all colors and intensified contrast across the entire field of view. Its Dual Spring Precision Adjustments perform with match-grade precision and, when paired with the Custom Dial System (CDS), long range shooting solutions have never been easier. The 30mm main-tube dramatically increases windage and elevation travel while the side focus adjustment makes fine-tuning parallax effortless. The easy-turn power selector can be quickly turned, even with gloves on while watertight seals ensure fog-free performance.
