My first prismatic red dot - Primary Arms CLx 1x18mm Prismatic Red Dot Sight

Glass is very clear. I have astigmatism, and the red dot never starbursts or anything. Does what I need it to do on my AP5. The mount allows me to use the iron sights on my AP5, though it doesn't really matter since it's a prismatic and the reticle is etched, but it's a plus.
