Multicoat 4: Light reflecting off lens surfaces diminishes image quality. So Leupold® engineers developed Multicoat 4®: a 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.

Quantum Optical System: The Quantum Optical System™ is a leap forward and provides a new level of optical performance for hunters and shooters. 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 using Leupold’s Zygo® Interferometer to minimize wave front error and increase resolution. The result is razor sharp imaging across the typical light conditions experienced on any hunt—from the bright daylight of varmint 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, resolution and color fidelity—all while preserving the ease of use and nearly indestructible ruggedness that has been a hallmark of Leupold rifle scopes for generations. 

Generous Eyebox: The generous eyebox makes it faster and easier to set your eye behind the riflescope and achieve a full, clear sight picture. Setting up for longer shots, you'll appreciate the flexibility it affords, and in close up big game or dangerous game situations, the quick target acquisition will be the difference maker. At high power, the longer eye relief and more generous eyebox gives you incredible head position latitude and an improved sight picture that fills the eyepiece completely - putting you in better position to make the shot of a lifetime.

BAS (Ballistic Aiming System): Leupold’s® Ballistics Aiming System™ is comprised of five specialized reticles – Boone and Crockett® Big Game, Varmint Hunter’s, LR Duplex, LRV Duplex, and the new SA.B.R. reticles – which take into account the variables crucial to accurate, long-range shooting. A special ballistics indicator ring allows users to customize their power settings for their cartridge ballistics, then saves that setting for easy reference in a hunting situation. With multiple aiming points for longer ranges and varying wind speeds, and infinite power selector settings to match your rifle ballistics, the Ballistics Aiming System can help you master the art of accurate, long-range shooting. It has proved so successful in helping hunters learn how to shoot accurately at long range, Leupold expanded your BAS options with additional reticles offering many of the same benefits as the original reticles. They also made them available in more riflescopes than ever. With practice, the Ballistics Aiming System will teach you how to gauge the distance to your target, where to place your reticle for that distance, and even how to compensate for wind deflection. With the Ballistics Aiming System and some practice, you’ll consistently make shots you wouldn’t have attempted in the past.

1/4 MOA Finger Click: Finger click adjustments for windage and elevation (¼-MOA) offer absolute repeatability and dependability over a lifetime of extreme use (metric adjustments – 1 cm per click).
