RM07: Trijicon RMR Sight Adjustable (LED) – 6.5 MOA Red Dot Developed to reinforce precision and accuracy with any style or caliber of weapon, the Trijicon RMR (Ruggedized Miniature Reflex) is designed to be as durable as the legendary ACOG. The RM07 is an LED sight powered by a regular CR2032 battery. Housed in rugged forged aluminum, the RMR is terribly tough yet lightweight. New easy-to-use adjusters with audible clicks allow for quick windage and elevation adjustments. With eight to be had brightness settings, the reticle will also be manually adjusted by pressing the plus or minus buttons on either side of the unit. To change to auto adjust mode simply press both buttons concurrently and release. To avoid wasting battery life turn the optic off by pressing both buttons concurrently and holding for 3 seconds. The Trijicon RMR is more difficult than any alternative and suitable for military, law enforcement and hunting applications.
