Description

The Leupold Mark 4HD 4.5-18×52 riflescope with the illuminated FFP PR1-MOA reticle (part no. 183623) carries an exceptional 125 MOA of total elevation range, giving this MOA-based reticle system enough turret travel for extreme distances most 4.5-18x scopes can’t dial to. Leupold keeps the illuminated PR1-MOA reticle first focal plane so it scales correctly with magnification, and a 25-yard minimum parallax setting sharpens focus on closer targets than the standard range covers. An M1C3 three-turn dial and side-focus parallax round out the control set. Among high-elevation-travel gun scopes in the Mark 4HD line, this illuminated PR1-MOA variant reaches further than its siblings.

Key Specifications

  • The magnification range is 4.5-18x, providing a 4:1 zoom ratio covering both close and precision long-range work.
  • The objective lens is 52mm, improving light transmission for better low-light performance.
  • The tube diameter is 34mm, giving increased internal adjustment travel for extended elevation correction.
  • The reticle is Illuminated FFP PR1-MOA, so holdover and windage values remain accurate across the entire magnification range.
  • Parallax is adjustable down to 25 yards, enabling sharp focus and accurate short-range zeroing.
  • Adjustment increments are 1/4 MOA, allowing fine, repeatable zeroing and correction.
  • The elevation system uses an M1C3 three-turn style dial with a 125 MOA total elevation range for extreme-distance dialing.
  • The field of view spans 23.1 to 5.2 feet per 100 yards, maintaining situational awareness at low magnification and target detail at high magnification.
  • The scope weighs 27 ounces, balancing rugged construction with manageable carry weight.
  • Illumination runs on a CR2032 battery, with multiple intensity settings for varied lighting.

Frequently Asked Questions

Why does this scope have 125 MOA of elevation? It’s built to reach extreme distances that would exhaust a standard scope’s turret before running out of visible target, useful for dedicated long-range shooters.

Is this the MOA or MIL version? MOA — the PR1-MOA reticle and 1/4 MOA clicks share the same measurement system throughout.
