Ingrained with the thrill of the hunt, the new VX-3 drastically improves optical performance, mechanical function, and durability. Leupold has pushed it to the limit, so you can push yourself to yours. Leupold VX-3, the new standard in riflescope performance. Exterior lens surfaces are treated with DiamondCoat 2, an ion-assist lens coating, for higher light transmission and the greatest level of abrasion resistance Leupold’s 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 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. 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. Crafted from 6061-T6 aircraft quality aluminum.
