Selling my Primary Arms Gen2 Multi-reticle Red Dot Sight. It's been working reliably on my 9mm AR up until recently. Right now, on occasion the dot (or any one of the other reticles for that matter) disappears - only to come back after a few seconds (or shots) or if you twist on the brightness dial. Bottom line, it isn't reliable enough for shooting matches anymore but for plinking it'll do just fine. It's a 90%er. I would part with it for $25.
