NXS™ riflescopes are built to standards that exceed virtually any other riflescope on the market. Each must pass a battery of tests—including side and front impact—that would destroy an ordinary optic. Only the highest quality, most durable components are used in NXS™ riflescopes, assuring a lifetime of repeatable precision. NXS™ lenses are painstakingly bedded with our proprietary Mil-Spec formulation, reducing any glass-to-metal contact that can result in breakages, stress, misalignment, and thermal shock. It’s how legends are built.
