The Leupold Mark 4HD 4.5-18x52mm delivers precision optics engineered for long-range shooting applications. This first focal plane scope combines Leupold's proven optical clarity with tactical-grade construction for demanding field conditions. The PR2 MOA reticle provides fast target acquisition and precise holdover calculations at extended distances.
What Makes This Different
The Mark 4HD series represents Leupold's evolution in tactical optics, featuring their Twilight Max HD Light Management System for superior low-light performance. The 34mm main tube provides 25% more internal adjustment range compared to 30mm tubes, delivering 80 MOA of total elevation travel. First focal plane reticle design ensures accurate ranging and holdover calculations at any magnification setting, unlike second focal plane alternatives that only provide accurate measurements at maximum power.
Key Features
- 4.5-18x magnification range with 52mm objective lens for optimal light gathering
- 34mm aircraft-grade aluminum tube with matte black finish
- First focal plane PR2 MOA reticle with illuminated center dot
- Twilight Max HD coating system maximizes light transmission across all conditions
- Side focus parallax adjustment from 50 yards to infinity
- Locking target turrets with 1/4 MOA click adjustments
- Waterproof, fogproof construction rated to withstand extreme temperature variations
Field testing demonstrates consistent tracking performance across the full adjustment range, maintaining zero retention through repeated cycling. The scope performs effectively in competitive precision rifle matches, hunting scenarios requiring extended-range shots, and tactical applications. Nitrogen purging prevents internal fogging during rapid temperature changes, while the robust construction withstands recoil from magnum cartridges without shift.
