Brings the reticle into focus quickly with Fast-Focus eyepiece

The Multi-coat 4® lens system delivers extreme clarity from edge to edge of the visual field, outstanding contrast, and a bright sight picture even in extreme low-light conditions.

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.

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

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.
