The flat dark earth RM05 Dual-Illuminated RMR Reflex Sight from Trijicon is an unmagnified targeting device that features a 9 MOA amber dot aiming point, battery-free auto-adjusting reticle illumination, and lightweight yet durable construction. The Ruggedized Miniature Reflex (RMR) has a forged aluminum housing with a wear, corrosion, chemical, chip, and scratch-resistant Cerakote ceramic coating. For additional reliability when paired with a heavy caliber pistol or rifle, the RMR has a tempered glass window and robust o-rings capable of maintaining their seal to a depth of 65 ft.

Trijicon's battery-free illumination system employs a tritium phosphor lamp and fiber optics to automatically adjust reticle brightness depending on ambient lighting conditions - day or night, indoors or outdoors. Impact point correction dials with 1 MOA audible clicks and a parallax-free multicoated sighting window make the RMR well-suited for close-range targeting atop almost any firearm. An array of optional RMR mounts enable the reflex sight to be rail-mounted or paired with a pistol, shotgun, or ACOG weapon sight.
