The versatile 3.6-18x magnification range helps you engage close targets, while also giving you the flexibility to reach out to long distances. With three revolutions of elevation adjustment and multiple reticle options, this scope will max out the performance of the latest long-range rifles and ammunition, guaranteed.

Built around Leupold’s Professional-Grade Optical System, the Mark 5HD offers unmatched light transmission that’s designed to outperform in the most challenging lighting conditions. Its industry leading glare reduction provides a clear image in harsh, direct light, while the resolution and clarity will meet the demands of any professional guide or shooter. Ergonomically designed with more tactile and audible click adjustments, larger numbers, and a high-speed throw lever, the Mark 5HD is built to put accurate fire downrange faster.

The unique combination of features, durability, and professional-grade optical performance guarantees that the Mark 5HD can handle any challenge you throw at it. It's 100% waterproof and fog proof, and like all Leupold® riflescopes, it's designed, machined, and assembled in the USA and guaranteed to perform for life.

Product Details:

5:1 Zoom Ratio:

A versatile 5:1 zoom ratio gives you 5 times more magnification at high power than at low power (model magnification ranges may be available in powers of 5x: 1-5, 2-10, 3-15, 4-20, etc.), so you can adjust your magnification to find the perfect balance between magnification and field of view for any situation. The larger the zoom ratio, the more versatile one scope can be.

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.

Zero Lock Dial:

The ZeroLock® system eliminates accidental dial movement by locking it in place.

Zero Stop:

The ZeroStop system creates a backstop when returning the dial back to zero, so you don't accidently turn the dial a full revolution in the wrong direction.

Lightweight Aluminum Housing:

Aluminum offers excellent durability and ruggedness without adding unnecessary weight.

Motion Sensor Technology (MST):

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.

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.

Side Focus:

The side focus adjusts the scope's parallax, making the reticle clearer and have less perceived movement when you're shooting at different distances.

Twilight Max HD:

The Twilight Max® HD Light Management Systems offers our clearest, brightest image with three main benefits: Best Light Transmission - Maximizes the most ambient light in low-light environments for extended visibility. Best Glare Management - Reduces more glare through maximum lens coatings and minimizes image washout caused by stray light. Best Contrast & Resolution - Creates the clearest possible image using premium high-definition, edge-to-edge lens prescriptions and additional HD lens coatings.


This scopes comes with an illuminated reticle, which can help you get on target faster in low-light situations.

ALUMINA® Flipback Lens Covers Included:

Our high-quality Alumina® flip-back lens covers thread onto the scope to protect the lens from moisture, dirt, and debris.

NightVision Compatible Illumination:

Micro-adjustable illumination brightness settings support modern night vision devices and can be fine-tuned to your equipment's sensitivity.


Leupold pioneered modern waterproof and fog proof 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.
