Trijicon RM08 Dual Illuminated RMR

The Trijicon RM08 Dual Illuminated RMR uses fiber optics and tritium to illuminate the reticle.  Fiber optics collect ambient light, automatically adjusting the reticle brightness. In situations with no light, the tritium illuminates the reticle. This version is popular with shooters who prefer a battery free solution.

The RM08 family features a 12.9 MOA triangle reticle in green or amber. The triangle can be used in two unique ways the tip of the triangle offers a fine aiming solution for precision shooting or shooting at distance, or the entire reticle can be used for quick acquisition in close shooting situations.
