Exterior lens surfaces are treated with DiamondCoat 2™, an ion-assist lens coating, for higher light transmission and the greatest level of abrasion resistance we’ve ever offered. DiamondCoat 2™ has the additional advantage of assisting in light transmission, for greater brightness, clarity and contrast, and will prove its worth in the wildest places on earth.

Features our exclusive, proprietary Argon/Krypton gas blend, which nearly eliminates the effects of thermal shock, and reduces the diffusion of gases sealed inside your scope even more than our proven nitrogen technology already does.

Get on target faster so you can take the shot of a lifetime. Even at higher powers, the longer eye relief and generous eyebox provides incredible head position latitude, edge-to-edge brightness, and a full clear sight picture that fills the eyepiece completely.

Blackened lens edges reduce light diffusion, so more usable light reaches the shooter’s eye. This results in a brighter image with increased contrast.

The twin bias spring exerts up to 30 percent more holding force on the erector, virtually eliminating erector system backlash and stress on the vital internal workings of the scope, for longer life.

The lockable super fast-focus eyepiece gets you on target fast. Includes a durable Alumina rubber eyepiece guard on select models.

Features Leupold's lockable fast-focus eyepiece for a secure reticle focus.

A versatile 3:1 zoom ratio erector system that is ideal for virtually any situation.

All Leupold® optics offer performance that makes them equally at home in hunting or tactical environments, thanks to their outstanding accuracy, legendary ruggedness, and absolute waterproof integrity.

The 30mm maintube offers incredible strength and allows for the greater range of windage and elevation adjustment.

M5 windage and elevation adjustment dials with audible, tactile 1/10-MIL clicks. Once sighted in, adjustment knobs can be zeroed.

The reticle magnifies along with the image, so you can estimate range at all magnification settings. These reticles are ideal in tactical situations, yet also provide greater accuracy of range estimation for hunters and target shooters.

The tactile power indicator identifies your magnification with a touch.

A 34mm maintube produces unparalleled windage and elevation adjustment travel.

Auto-locking, push-button elevation adjustment for rock-solid reticle adjustment. Features .01 mil clicks, 2 turn zero stop with revoultion indicator.

The Xtended Twilight Lens System™ optimizes the transmission of low-light wavelengths, so you see the details of low-light scenes in greater, brighter detail than with any other scope available.
