I have some Primary Arms optics. They have performed quite well on .22s over the past couple years and tens of thousands of rounds. However, I'd pass on their reflex sight based on the one I have seen. It's a 5MOA green dot that has no manual brightness settings. The brightness is controlled by a light sensor but indoors or outside it's just WAY too bright to comfortably use. From what I have read on forums, the brightness control ( lack of) seems to be a common complaint. The guy who bought it returned it to Primary Arms no questions asked and ordered another MicroDot.
