Ready your rifles with a versatile Mark 4HD. We took the legendary performance of its predecessors and gave it a slimmer maintube that’s been packed full of professional-grade features. Whether you’re a dedicated enthusiast or a seasoned expert, the Mark 4HD’s optical clarity and lightweight design will get the job done at the range or in the field.
 
The Mark 4HD series features five magnification ranges, providing you with an accurate and reliable option for close-quarter engagements, long-range dominance, and everything in between. They’re available with a three-turn elevation dial for unmatched confidence at extreme distances, a precise ZeroLock windage adjustment that won’t budge when knocked around, and a side focus that delivers tack-sharp images as close as 25 yards. And like all Leupold riflescopes, they’re waterproof, fogproof, and backed by our lifetime guarantee.

Features
A 4:1 zoom ratio strikes the perfect balance between weight and versatility, giving you plenty of magnification options without weighing you down. Model magnification ranges are available in powers of 4x: 1-4.5, 2.5-10, 4.5-18, and 8-32.
The 25-yard side focus allows you to adjust the scope's parallax from 25 yards to infinity, ensuring a crisp, stationary reticle at almost any distance.
Leupold’s Professional-Grade Optical System offers unmatched light transmission that’s designed to outperform in the most challenging lighting conditions, industry-leading glare reduction for a clear image in harsh, direct light, and the resolution and clarity that professional guides and shooters demand in the field.
Motion Sensor Technology (MST™) extends battery life by automatically deactivating illuminated reticles after five minutes of inactivity and then reactivates instantly as soon as movement is detected.
The removable, low-profile throw lever makes changing magnifications quick and easy. It includes a thread protector plug to use when the lever is removed.
These low-profile dials are available on select models and provide up to 71.5MOA of adjustment in 3 revolutions and 1/4 MOA clicks. Visual and tactile revolution indicators ensure you don’t get lost in the travel. The ZeroLock® feature prevents inadvertent adjustments and ensures accurate return to zero.
In First Focal Plane (front focal plane) scopes, the reticle grows and shrinks at the same rate as the target when you adjust the magnification. This allows you to accurately use the reticle feature at any magnification setting. These reticles are ideal in tactical situations but can also aid in range estimation for hunters and target shooters.
Leupold's Custom Dial System® (CDS®) gives you the ability to customize your turret (adjustment dial) to your exact ballistics and environmental conditions. Once your new custom dial is installed, simply range the target, turn the dial to that number, and aim dead on.
Leupold pioneered modern waterproof and fogproof technology using advanced internal gasses and sealing methods that withstand extreme temperatures, elevation changes, and shocks, so the internals of the optics stay moisture free and crystal clear for life.
