Leupold Mark 4HD Features The Leupold Mark 4HD is built on a 34mm main tube and uses a first focal plane reticle design meaning the illuminated PR2-MOA holdover marks scale accurately with magnification for consistent ranging at any power setting. The three-turn elevation dial provides extensive adjustment range for confidently engaging targets at extreme distances while the ZeroLock windage adjustment won t budge when knocked around in the field or during transport. Illumination brightness settings let shooters adapt the reticle for low-light conditions keeping the aiming point visible from dawn to dusk. A side focus parallax adjustment lets shooters dial in razor-sharp images from as close as 25 yards out to distant targets. Like all Leupold riflescopes the Mark 4HD is waterproof and fogproof standing up to harsh weather and extreme temperature swings without fail. The CR2032 battery delivers up to 1600 hours of illumination runtime ensuring the reticle stays powered through extended hunts or long days at the range. With an eye relief of 3.90 to 4.20 inches and a matte black finish the scope is built for both comfortable behind-the-glass use and a low-visibility profile in the field. This combination of durability precise adjustments and reliable illumination makes the Mark 4HD a dependable choice for serious long-range shooters.
