The Leupold Mark 4HD 4.5-18x52mm riflescope with the illuminated PR1-MIL reticle (part no. 183624) adds reticle illumination and a closer 25-yard parallax minimum to the mil-based Mark 4HD platform, useful for shooters working targets nearer than the standard focus range covers. Leupold keeps the PR1-MIL reticle on the first focal plane, so holdovers and subtensions scale correctly with magnification, and the illuminated aiming point stays visible in low light. At 27 ounces this is one of the lighter builds in the 34mm Mark 4HD family. Among illuminated gun scopes for precision shooting in variable light, this PR1-MIL configuration covers both close and long-range work.

Frequently Asked Questions

Why does 25-yard parallax matter here? It lets the scope focus sharply on closer targets than the standard Mark 4HD parallax range covers, useful for varied-distance stages or hunting setups.

Is illumination adjustable for brightness? Yes, the CR2032-powered reticle offers multiple intensity settings for different lighting conditions.
