my humble review of the trijicon rmr ( rm07 6.5dot) red dot sight on a glock 17.in my opinion this is the future of pistol shooting,an outstanding system but only paired with fixed suppressor sights ,they help the shooter find the dot and allow for a backup sight when the rmr fails.now the bad the rmr sight is not ready for prime time.my first sight lasted 400Rd's the lens came unglued and out of focus to the point where the backup sights were unusable.i called trijicon and was met with ambivalence and directed to the website for a return repair invoice,i did receive it 4 days later.i was not happy after talking to trijicon ,so i called brownells for a replacement sight, i called on a Monday and had a replacement sight on Wednesday. outstanding service.so i mount the new sight and off to range to sight in ,at approx 100 Rd's the lens came unglued and out of focus. one can not rely on a combat sight that has the lens glued in place-if trijicon corrects this problem then and only then is it a good usable sight and an outstanding shooting system- PS i tried to post a question about the service life of the rmr on another forum with 20+pages of rmr info and was banned for life?????
