Multicoat 4

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.

2nd Generation Argon/Krypton Waterproofing

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.

Dual Use

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 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.
