Cool product, high quality - Meprolight M21 Self-Powered Day & Night Reflex Sight w/ Dust Covers

I typically run Aimpoints and Eotechs but decided to give this a go for a more authentic look on my X95. Full disclosure, I much prefer active illumination, which I knew, and the only thing I don't like about the M21 is the lack of reticle brightness and adjustability, and there is no etched black base reticle like an ACOG (that you could use with the fiber optic covered). That aside, the optic is rock solid, the mount is rock solid. I assume the glass is tinted to provide more contrast with the passive reticle, but its not too dark. I really like the triangle reticle, similar aiming strategy to an ACOG. Overall, this is a solidly build optic, it's just not for me.
