This red dot not only looks great, but performs great! The only issue I have had with it so far is the battery tray. It closes with no issues, but the rubber O ring seems to be a little too loose and it likes to scoot out of the way a little bit. I had to hold it in place with the tool for the optic while pushing the tray closed before tightening the screws for it down. -1 star. Not a huge concern since I shouldn’t have to worry about the battery being changed anymore than other optics. Additionally, it is nice not having a huge dial on the side of it obstructing my view. That was the main selling point for me on this optic. +1 star.

The reticle is a little bloomy with my astigmatism, but the optic is rugged and reliable with solid battery life

Great value… it seems higher quality than expected. Solar failsafe and multiple reticles are a nice extra. It also includes two mounts. Biggest issue so far is that it was kind of hard getting the battery door closed. The o ring seemed to prevent it closing as tight as the pictures show.

Solid optic, quick shipping and an excellent price! The inclusion of two mount heights is a definite plus as well
