The Trijicon MRO leaked datasheets have been making waves across the internet. The optic is very small, not much larger in width and height than the generous 25mm objective lens. It has a snag free design with nothing protruding from it other than the brightness adjustment dial. This combined with 5 years of battery life off a single CR2023 makes for a compelling backup sight.
Pricing has been rumored to be about ~$500. A trusted source of mine sent in the below image showing the retail price to be $579 for the optic without a mount. That said, I was also told that the dealer pricing is VERY aggressive, so expect dealers to push these aggressively and for them to sell below MSRP.
I think Trijicon might be onto a winner here!
