Leupold Mark 4HD 4.5-18x52 34mm M1C3 FFP Illum PR1-MOA Scope LU183623

The Leupold Mark 4HD 4.5-18x52 34mm M1C3 FFP is a high-performance riflescope built for shooters who need absolute reliability when dialing for distance. The biggest hurdle in long-range shooting is "mechanical doubt"—the fear that your turrets won't track perfectly or return to a true zero after a long day of adjustments. This optic eliminates that anxiety by pairing the rock-solid M1C3 ZeroLock turret system with a first focal plane reticle, ensuring your point of impact stays exactly where you put it.

The real strength of this scope is its consistency. Because it uses a first focal plane (FFP) design, the PR1-MOA reticle scales perfectly as you zoom, so your holdovers stay accurate whether you are at 4.5x or 18x. The beefy 34mm maintube isn't just for show; it provides the extra internal room needed for a massive 125 MOA of elevation travel and increased structural toughness. When you combine that mechanical precision with Leupold’s Professional-Grade Optical System, you get a scope that tames glare and pulls in every bit of usable light when the sun starts to dip.

Built around a rugged 34mm aluminum housing, this Mark 4HD offers the heavy-duty elevation travel required for extreme long-range shots. The M1C3 ZeroLock turrets provide crisp, tactile 1/4 MOA clicks that you can feel even with gloves on, while the large 52mm objective lens and motion-activated illumination keep your sight picture bright and your reticle visible in the toughest lighting. It is a specialized tool designed to give you total dialing confidence from dawn until dusk.
