Hit your target in the darkest of nights with Firefield® night vision. The NVRS 3x42 Night Vision Riflescope is engineered with a built-in, high power IR illuminator that enhances image details and increases viewing range in total darkness. Its quick-detach weaver mounting system makes it easy to change optics or switch to iron sights, and still maintain return-to-zero reliability. Featuring a 42mm lens for higher light gathering capabilities and a powerful 3x magnification, the NVRS 3x42 offers a clear picture of medium- to long-range targets. Its rock-solid, lightweight titanium body and flip-up lens covers shield it from impact and harsh weather conditions. The flip-up lens covers open to reveal enhanced, multi-coated optics and an illuminated red duplex reticle with incremental brightness adjustment, allowing the shooter to quickly adapt to their surrounding environment.
