Developed to improve precision and accuracy with any style or caliber of weapon, the Trijicon RMR (Ruggedized Miniature Reflex) Type 2 is designed to be as durable as the legendary ACOG. The RM01 is an LED sight powered by a standard CR2032 battery. Housed in rugged forged aluminum, the RMR Type 2 is extremely tough yet lightweight. New easy-to-use adjusters with audible clicks allow for quick windage and elevation adjustments. The new Trijicon RMR Type 2 is tougher than any alternative and suitable for military, law enforcement and hunting applications. Comes installed on a RM36 mount for use on 1.5x, 2x, and 3x ACOG rifle scopes. Mfg: Trijicon
