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.


  • 4:1 ZOOM RATIO: A 4:1 zoom ratio strikes the perfect balance between weight and versatility, giving you plenty of magnification options without weighing you down.
  • 25 YARD SIDE FOCUS: 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.
  • PROFESSIONAL GRADE OPTICS SYSTEM: 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.
  • M5C3 ZEROLOCK ADJUSTMENTS: These low-profile dials are available on select models and provide up to 30-MILs of adjustment in 3 revolutions and 0.1 MIL 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.
  • CUSTOM DIAL COMPATIBLE: 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.
  • FIRST FOCAL PLANE: 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.
  • ZEROLOCK WINDAGE DIAL: The ZeroLock® system prevents accidental dial movement and allows for repeatable returns to zero.
  • WATERPROOF, FOGPROOF, SHOCKPROOF: 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.
