The Leupold Mark 4HD 8-32x56mm M5C3 Riflescope is engineered for extreme long-range tactical deployment, merging an expansive 8-32x power range with a light-gathering 56mm objective lens. Constructed on a heavy-duty 34mm maintube, it incorporates the tactile M5C3 turret system that delivers 0.1 MIL clicks across three full revolutions alongside a push-button ZeroLock mechanism to stop accidental adjustments. It is equipped with a crisp, illuminated first focal plane PR3-MIL reticle, mapping clean holdovers and accurate calculations at all magnification levels. Driven by Leupold's Professional-Grade Optical System, the glass yields brilliant resolution and high light transmission even in challenging environments. Side focus dials correct parallax distortion down to 25 yards, while integrated Motion Sensor Technology (MST) actively monitors idle time to save battery life.
