Holosun red dot - Holosun Paralow 2 MOA Dot Red Dot Sight 1x20 mm

The price is decent and does not break the bank. I took it out to the range, and it held its zero. Reviewing the manual reveals all the light settings. The only issue is that there is no way of switching off the red dot, so that would be my only con about the optic. Overall, it is nice and sleek, and it fits other riser rail mounts, which is what I ended up doing with mine.
