The 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 (or low) light, the tritium illuminates the reticle. This version is popular with shooters who prefer a battery-free solution. The RM05 family has a green 9.0 MOA dot, which is simple to use and easy to find. The U.S. Marine Corps chose the 9.0 MOA dot for use in both the SDO and MDO optics programs.Features: Unique, patented housing shape diverts the force of an impact away from the lens, greatly increasing durability.Creates a wide-band light transmission for minimal change in target area color.No need for special tools. 1 MOA per click.Tritium-phosphor lamp illuminates reticle in low-light conditions and fiber optics automatically adjust the brightness level and contrast to available light conditions.Easy-to-use buttons on the sides of the optic allow the user to adjust the illumination brightness, toggle between manual and automatic modes, and power down the RMRA(R) for storage.Multiple primary applications including rifle, pistol, shotgun, and carbine, or use as a secondary sight with a magnified optic.Designed to be waterproof to 20 meters (66 ft.)#html-body [data-pb-style="62DF82898351D"]{justify-content: flex-start; display: flex; flex-direction: column; background-position: left top; background-size: cover; background-repeat: no-repeat; background-attachment: scroll; border-style: none; border-width: 1px; border-radius: 0px; margin: 0px 0px 10px; padding: 10px;}#html-body [data-pb-style="62DF82898352A"]{border-style: none; border-width: 1px; border-radius: 0px; margin: 0px; padding: 0px;}
