My first trijicon rmr - Trijicon RM06 RMR Type 2 1x16mm Reflex Red Dot Sight

I brought this red dot for my VP9 optic ready slide, good so far. Surprisingly its smaller than I expected. Installation was simple and easy, convenient to have a torque wrench for proper mounting. I appreciate the auto adjustable dot brightness during change in light conditions. The glass has a light greenish tint that I perfer for it to be clear. I havent abused it yet but confident it'll hold up if it come down to that situation. Im debating if I should buy another one for my gpr AR15.
