Trijicon RMR Adjustable (LED) Sight 3.25 MOA Red Dot, Coyote Brown

First, the RMR06-HRS (Coyote) that I received in Nov 2019 was verified to be authentic by Trijicon.An amazon review really won’t do this optic justice, and if you’re considering one, it’s likely that you’ve done the research elsewhere, or are familiar with the sight.The 3.25 MOA reticle is clear and easy to spot, and I’ve tried to find fault in the thing. It’s not magically there–alignment is just as important as with irons, but if I do my job (and practice), it shows up right where I’d expect. In my very limited range time since getting this, I tend to agree with what I read prior to making the purchase: it’s almost imperceptibly slower than iron sights at close range, and markedly faster past about 7 yards. To me, the trade off for greater versatility and confidence with difficult shots is worth it.Fit and finish are what I’d expect: nice looking dark coyote/FDE hard anodizing (not Cerekote on this model), and a piece of equipment that looks and feels like it will outlive me, regardless of how much I (ab)use it.Of note, for mounting on a Glock MOS slide, a RMR Glock Mounting kit is needed; it includes a sealing plate and correct-length screws to interface with the MOS adapter plate (the ones included with this item are too long for that purpose). Mounted as such (or against any flat, smooth surface) it is designed to be waterproof to over 60 feet.A few other particulars that I was wondering about prior to purchase: This model can be turned off manually, but batteries will last over four years always left on. It auto-adjusts, just like the non-manual adjusting LED model, and defaults back to this setting after 16.5 hours if manually adjusted. I have never found conditions where it doesn’t auto-adjust to what I perceive to be the best level, though some internet reviewers have reported conditions it struggles with. I find the ability to dim it at the range makes it easier to sight in, and very nice for practice with iron sights. For the few with night vision, the manual reports that it has a NVD setting.
