The RMR Type 2 Adjustable LED sight puts the illumination control in the users hands. 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 RMR for storage. The automatic mode functions the same as the LED RMR version. If a manual mode has been chosen the RMR will remain in manual mode for 16.5 hours following the last push of a button. After 16.5 hours the optic will default back to the automatic mode so that the RMR will be ready for your next mission or task. All RMR Type 2 Adjustable LED sights are compatible with night vision devices with the 3.25 dot size being the most popular. The user can also lock out the buttons so that the RMR functions in automatic mode only. This ensures that inadvertent button pushes do not cause a loss of aiming solution. The 6.5 MOA dot in the RM07 gives the user the biggest dot available in our LED and Adjustable LED operated models. The bigger dot size gives the user the ability to locate the dot quickly which is ideal for close quarter engagements or is a great solution for those who have vision problems.*Does not include mount. The RMR Type 2 has identical physical dimensions and mounting footprint to that of the original RMR Type 1. If selecting an RMR for mounting on the Glock MOS Springfield OSP Walther PDP or H&K VP9 Optics Ready a Trijicon RMR mounting kit AC32064 is required.
