Leupold® Mark 3HD™ 1.5-4x20mm Riflescope AR-Ballistic Reticle


SKU: LEU180670 Categories: ,

We have a long history of manufacturing rugged and reliable riflescopes that outperform and outlast everything else on the battlefield and in competition. We used that heritage to create an extremely versatile line of tactical scopes for the shooter looking to upgrade every long gun in their safe. The Mark 3HD™ 1.5-4x20mm provides a wide field of view, while also allowing for precise, close to mid-range shots.

Complete with MIL-based adjustments and reticles, HD performance, an exposed elevation adjustment dial, and a low-profile power selector with integrated throw lever, the Mark 3HD series is perfect for anyone who needs a rugged, precise, and repeatable scope. Built around Leupold’s Elite Optical System, it offers the light transmission, glare reduction, and resolution that diehard hunters and shooters demand for all-day performance.

And like every Leupold® riflescope, the Mark 3HD was designed, machined, and assembled in our Oregon factory. We test it to ensure it’s absolutely rugged, 100% waterproof and fogproof, and then we guarantee it for a lifetime of performance.


  • 3:1 Zoom Ratio
    • A 3:1 zoom ratio is very common in many scope models. It gives you 3 times more magnification at high power than at low power, so you can dial your power down for close encounters or all of the way up for long-range shots.
  • High Definition
    • High-definition, calcium-fluoride lenses ensure incredible clarity at all magnification levels.
  • Removable Throw Lever
    • 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.
  • 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.

    • Specifically designed for .223 AR-style rifles
    • Based on a Duplex® style design
    • Provides holdover hash marks for quick target engagement
