Leupold Mark 4HD 4.5-18x52mm Rifle Scope FFP Illuminated MOA

The Leupold Mark 4HD 4.5-18x52mm delivers precision optics engineered for demanding long-range applications. This first focal plane riflescope combines Leupold's proven reliability with advanced illumination technology and tactical-grade construction.

What Makes This Different

The Mark 4HD features a 34mm main tube that provides 25% more internal adjustment range compared to standard 30mm scopes. The first focal plane PR1-MOA reticle maintains consistent subtension relationships across the entire magnification range, enabling accurate holdovers at any power setting. Leupold's Twilight Max HD Light Management System maximizes light transmission during critical dawn and dusk shooting periods.

Key Features

• 4.5-18x magnification with 52mm objective lens for extended range capability
• 34mm main tube construction provides 80 MOA elevation and 50 MOA windage adjustment
• Illuminated PR1-MOA first focal plane reticle with 11 brightness settings
• Scratch-resistant Diamondcoat 2 lens coatings on all air-to-glass surfaces
• Aircraft-grade aluminum construction with matte black anodized finish
• Side focus parallax adjustment from 50 yards to infinity
• Capped low-profile turrets with 1/4 MOA click adjustments

Field performance remains consistent across temperature extremes from -40°F to 140°F. The scope maintains zero through heavy recoil and vibration, making it suitable for precision rifle competitions, tactical applications, and long-range hunting. Fully multi-coated lenses deliver 92% light transmission while the nitrogen-filled tube prevents internal fogging in humid conditions.
