The Leupold Mark 5HD 3.6-18x44mm FFP TMR Reticle 35mm Tube scope is a lightweight yet rugged optic designed for serious shooters and hunters who demand peak performance and reliability, offering edge-to-edge clarity, outstanding low-light capability, and a lightweight profile that weighs up to 20 ounces less than comparable scopes. Built around a 35mm tube with a 44mm objective, it delivers a generous eyebox and smooth operation with three revolutions of elevation adjustment and tactile, audible clicks for rapid, precise changes in the field, while the front focal plane design ensures the Combat Competition Hunter reticle scales with magnification for accurate wind, holdover, and range estimation at any distance. Constructed from 6061-T6 aircraft-quality aluminum and sealed with advanced Argon/Krypton waterproofing, this scope is built to withstand harsh conditions, and the Twilight Max HD Light Management System enhances visibility in dim light at dawn or dusk. The M5C3 ZeroLock Elevation Adjustment, combined with a high-speed throw lever, provides rapid target acquisition and confident long-range shots, making it an ideal choice for both range work and serious hunting applications.
