The Leupold Mark 4HD 4.5-18x52mm delivers precision optics engineered for long-range shooting applications where target acquisition and tracking matter most. This first focal plane riflescope combines Leupold's proven optical performance with tactical features demanded by competitive shooters and precision rifle enthusiasts.
What Makes This Different
The Mark 4HD series represents Leupold's commitment to delivering professional-grade optics at a more accessible price point than their flagship Mark 5HD line. The 34mm main tube provides 25% more internal adjustment range compared to standard 30mm tubes, while the first focal plane PR2 MIL reticle maintains accurate subtensions at all magnification levels. The 4.5-18x magnification range offers versatility from mid-range engagements to extended precision shots.
Key Features
- First focal plane PR2 MIL reticle with precise holdover points and windage references
- 34mm aircraft-grade aluminum tube with matte black Type III hard anodized finish
- 52mm objective lens with fully multi-coated Twilight Max HD optical system
- 4.5-18x magnification range with side focus parallax adjustment from 50 yards to infinity
- Capped 1/10 MIL tactical turrets with audible and tactile click feedback
- 30mm of total elevation adjustment and 15mm of windage adjustment per direction
- Fast-focus eyepiece with 3.7-inch eye relief across magnification range
Field performance centers on the scope's ability to maintain zero under recoil and environmental stress. The nitrogen-filled tube construction prevents internal fogging in temperature extremes, while the scratch-resistant lens coatings maintain clarity in harsh conditions. Competition shooters benefit from the precise tracking characteristics of the tactical turrets, which return to zero reliably after dialing for distance. The PR2 MIL reticle provides clean sight picture with minimal obstruction while offering multiple aiming points for quick follow-up shots.
