"The Leapers UTG 4x32 Wide Angle Crossbow Scope is a durable, accurate scope for crossbows with the wide-angle field of view necessary for reliable hunting with the slower, less powerful bow system. The Leapers crossbow scope is built on the robust True Strength platform, meaning it is Rain-Proof, fog proof and shock proof. What makes this scope great for crossbows is its Pro 5-Step rangefinding reticle, which is specially calibrated for estimating range on a 300fps crossbow, helping you make more accurate distance shots. The reticle of the Leapers UTG 4x32 Illuminated Wide Angle Cross Bow Scope can also be illuminated in either red or green using the SWAT (Side Wheel Adjustable Turret) dial on the side of the scope, which makes for easier low-light shooting, especially when combined with the broadband lens coating on the UTG scope. For even more long-range precision, Leapers has equipped the crossbow scope with premium zero-resettable and zero-lockable target-style windage and elevation turrets and its integral angled sun shade will eliminate glare.|Built on Robust True Strength Platform|Integral Pro 5-Step Illumination Reticle for Quick Aiming Acquisition|Side Wheel Red/Green Dual Illumination for Versatile Uses in Different Light Conditions|Superior Quality Precision Broadband Lens Coating Offers a Generous Field of View|Features Premium Zero Lockable and Resettable Target Turrets|Complete with Flip-open Lens Caps and QD Ring Mounts|Parallax Pre-adjusted at 50 Yards|Built in Integral Angled Sunshade"
