Having owned my MRO for about 10 months now, I definitely feel it's a good optic for the money and am generally happy with my purchase. Having heard of some of the QC issues on this model, I was definitely a bit hesitant at first, but mine has performed very well so far and have a lot of confidence in Trijicon that they stand behind their products. All that being said, the MRO is not a perfect red dot and if you are seriously interested in purchasing it, there are a few things you should know about it beforehand. If you can live with these issues, then you will probably be very happy with it. Bluish Hue: The optical clarity of the MRO is quite excellent, just like every other Trijicon optic I've used, but when shooting with both eyes open, there is a slight, but noticeable bluish hue to the lens. I have however found this coloration is more noticeable indoors than when used in natural light outdoors. Though I personally prefer a more colorless optic, I don't think it's an issue and hasn't adversely affected the function of the optic on any practical level. Magnification: For me, this is the biggest con of the MRO and something that caught me by surprise when I first tried it. This optic has a very, very slight, but noticeable amount of magnification to it. When shooting with both eyes open, the closer you are to the target, the more noticeable the magnification becomes. On a practical level, it doesn't really affect function for me, though if I were using it more in very close quarters, I might have more of an issue with it. Regardless, for $500 +/-, it's a little disappointing considering I've used Holosun optics that were less than half the cost of the MRO that didn't have these issues, are perfectly clear and close to, if not as durable. Glare: Yes. In certain situations there is some glare to this optic and if you crank up the brightness too much in darker spaces, you will notice this, and in some cases, a halo effect. Glare will also be an issue when exposed to direct sunlight. Part of this I attribute to the large objective and feel that's just a price you pay, although I imagine some of it may be reduced with the use of a kill flash. Regardless, when using the correct brightness settings for your environment, most of these potential issues shouldn't give you any problems. Lens covers: There are not a whole lot of options for lens covers for the MRO and the ones you can find are severely overpriced in my opinion. Fortunately, I found a tip online that suggested the Butler Creek #17 for the front objective and sure enough, it works great! Highly recommended. Summary: Overall I definitely like my MRO very much. But if you're seriously in the market for one, I would strongly suggest trying it out first before buying and especially, comparing it to other red dots like the AimPoint Micro as there are distinct Pros/Cons to each that will likely influence your preference. Lastly, unless you are LEO or Military, I would also suggest also comparing it to some of the Primary Arms / HoloSun optics offer some very competitive options at less than half the cost.
