The Leupold VX5HD 4-20×52 ZL3 TMOA rifle scope features a fast-focusing eyepiece for quick reticle focus and side focus parallax adjustment that helps from any position. It has a versatile 4-20x zooming range, giving you a wide field of view. The rear focal plane TMOA reticle is fine and minimally covers the target as sub-tensions change with zoom and tune the ballistic reticles. This Leupold VX5HD 20×52 ZL3 TMOA offers a 52mm objective lens with a Guard-Ion-assisted coating, protecting it from scratches and other abrasions, and is sealed to ensure 100% waterproof and fog proof. The Twilight Light Management System adds up to an extra 30 minutes of shooting rays and eliminates 90% more glare.
