    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 optic, great price and Fastest shipping around!

    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
