LEUPOLD Mark AR MOD 1 4-12x40mm Rifle Scope

Light reflecting off lens surfaces diminishes image quality. So Leupold® engineers developed Multicoat 4®, our own proprietary lens coating system to keep image quality pristine. Multicoat 4 greatly increases the amount of all available light that reaches your eye, while at the same time, it minimizes the reflections of the sky on the outer eyepiece. You’ll never be able to control the light, but with Leupold’s Multicoat 4, you can always make the most of it.

Leupold mechanical and optical scientists, mechanical engineers and product line managers. have dedicated their design efforts over the last year to developing the optical system for Leupold’s newest generation of riflescopes, including the VX-1, VX-2, VX-R and VX-6. The Quantum Optical System™ is a leap forward and provides a new level of optical performance for hunters and shooters. Using the rugged foundation of the legendary Vari-X series and employing state-of-the-art optical and mechanical design software and manufacturing processes, this system delivers new levels of performance in every optical category. Lead free, ecologically friendly glass compositions are used throughout—the geometry of each lens is maximized through a combination of Ze-max® design software and evaluation usingLeupold’s Zygo® Interferometer to minimize wave front error andincrease resolution. The result is razor sharp imaging across the typical light conditions experienced on any hunt—from the bright daylight of varminting to the dawn and dusk hours when big whitetails are on the move. By repositioning optical elements, employing new coatings and importantly, leaving key, time-tested mechanical aspects of the Vari-X system untouched, significant performance gains have been achieved in many other areas as well. The Quantum Optical System has greatly enhanced light transmission (up to 92% in the VX-1 system and 94% in the VX-2 system), resolution and color fidelity—all while preserving the ease of use and nearly indestructible ruggedness that has been a hallmark of Leupold riflescopes for generations.

While we still waterproof other optics with bone-dry nitrogen – technology pioneered by Leupold® – Select models feature our exclusive, proprietary Argon/Krypton gas blend. Its advantages are two fold: it nearly eliminates the effects of thermal shock, and the Argon/Krypton molecules are significantly larger than nitrogen molecules, reducing the diffusion of gases sealed inside your scope even more than our proven nitrogen technology already does. We pioneered riflescope waterproofing, and now with Argon/Krypton we’re exceeding the standards we set ourselves.

Outstanding accuracy, legendary ruggedness, and absolute waterproof integrity. All Leupold® optics offer performance that makes them equally at home in hunting or tactical environments. Leupold Mark 4® Long Range/Tactical riflescopes are excellent choices for both long-range hunting and varminting. Likewise long-range competitive shooters and members of the Fifty Caliber Shooters Association – men and women who shoot competitively at ranges of 600 yards or more – rely on the accuracy and durability of these scopes.See overview of each product for more detailed information on hunting, shooting, and competition applications.
