Leupold Mark 4HD 4.5-18x52 34mm M5C3 FFP - Illuminated PR1-MIL Reticle - Rifle Scope

The Leupold Mark 4HD 4.5-18x52mm with illuminated PR1-MIL reticle is the only Mark 4HD variant that includes an electronic reticle level. The level flashes when the scope isn't level, promoting more accurate long-range shots and simplifying the mounting process — a meaningful advantage when shooting at distance.

The Leupold Mark 4HD is a 4.5-18x52mm first focal plane riflescope with an illuminated PR1-MIL reticle, 34mm maintube, M5C3 ZeroLock adjustments, precision side focus, electronic reticle level, and Daylight Bright Illumination.

Daylight Bright Illumination keeps the reticle visible even in direct sunlight. Motion Sensor Technology (MST) extends battery life by automatically deactivating the illumination after five minutes of inactivity and reactivating instantly when movement is detected. The electronic reticle level flashes to indicate when the scope is off-level, which helps reduce cant-induced error at long range. The first focal plane PR1-MIL reticle scales accurately across the full 4.5-18x range, and the precision side focus adjusts parallax from 25 yards to infinity. The M5C3 ZeroLock elevation dial provides up to 36 MILs of total adjustment in 0.1 MIL clicks across three revolutions. A revolution indicator keeps you oriented in the travel.
