These Leupold VX-6 1-6x24 Riflescopes have unique features you can imagine - legendary ruggedness, stunning optics, and a huge 6x zoom ratio that shortens the distance to your next trophy. The Twin Bias Spring Erector System features beryllium/copper alloy leaf springs to withstand the most intense abuse. Built with up to 30 percent more holding force, it virtually eliminates erector system backlash and stress. The VX-6 riflescope offers better optical clarity as a result of its meticulously cut and polished, lead-free glass lenses. In addition to its superior optics, the lenses are produced with none of the environmentally damaging by-products common to standard glass production. Another Leupold-unique feature the blackened lens edges, which work to reduce unwanted glare and diffusion through the lens edges. By using edge blackening, stray light is absorbed rather than reflected, resulting in better resolution, improved contrast, and superior optical performance: no matter what the conditions.
