Leupold Mark 4HD Features Because the Mark 4HD s PR2-MIL reticle sits in the first focal plane its holdover marks scale correctly with magnification meaning the ranging and holdover references stay accurate whether the shooter is dialed to 6x or 24x a critical feature for anyone using the reticle itself to estimate range or hold for wind and drop rather than dialing turrets. The three-turn elevation dial provides an extended range of adjustment for genuinely long shots while still giving the shooter tactile feedback about which rotation they re on reducing the risk of a shooter losing track of turret position under pressure. ZeroLock windage adjustment mechanically locks the turret at zero preventing accidental movement from bumps or snags during transport or from brushing against gear in the field so the shooter s zero stays exactly where it was set. The side focus parallax adjustment allows tack-sharp images at distances as close as 25 yards useful for shooters who move between close and extended engagement distances. At 34mm the scope s tube diameter provides more internal adjustment travel than a standard 30mm tube giving shooters more elevation and windage range to work with at extreme distances before running out of adjustment. The scope is fully waterproof and fogproof tested to withstand demanding field conditions and backed by Leupold s lifetime guarantee for long-term peace of mind. At 30 oz the Mark 4HD carries a moderate weight typical of a serious long range optic in this magnification class. For shooters who need a genuinely repeatable rugged optic across a wide range of engagement distances the Leupold Mark 4HD is available for sale at GrabAGun.
