Trijicon’s technologically advanced Reflex sights offer shooters the perfect combination of speed and precision under virtually any lighting conditions. Their compact size allows for the fastest target acquisition possible, reliable mounting to nearly any weapon, and consistent performance under any conditions. Adjustment is made easy with audible clicks on windage and elevation adjustments. The Dual Illuminated RMR do not use batteries; instead, these RMR sights are illuminated by fiber optics when natural light is available, and the reticle is lit by tritium when in darkness.
