Very good optic for the money - SIG SAUER Romeo5XDR 1x20mm Red Dot Sight

I do like that the battery life is north of 40k hours. I do like the reticle, but there are some distracting visual artifacts in some lighting conditions. There are four reticles to choose from which is very cool, especially at the price point. The emitter creates a halo effect at certain brightness levels and there's a strange reflection in the glass that I find to be somewhat distracting. I would recommend this optic to those that are Predator movie franchise fans and those that prefer green dot sights.
