The flat dark earth RX30 Dual-Illuminated Reflex Sight with 6.5 MOA Amber Dot Reticle from Trijicon features a 1x magnification and a dual reticle illumination. While the fiber optic illumination provides light for the reticle during the day, the tritium lamp works at night. With this dual-illumination system, you don't need to use any batteries or power supplies. The true-color multiple anti-reflection lens coatings provide images with realistic color and improved brightness and visibility in low-light conditions. The non-magnifying optical system also offers a wide field of view and parallax-free aiming. The ultra-rugged water-resistant aluminum alloy housing is light and durable and has an abrasive- and corrosion-resistant Cerakote finish. The sight can be easily mounted on optional Picatinny or Weaver style rails.
