Great for price point - SIG SAUER OPMOD Romeo5X 1x20mm 2 MOA Dot Compact Reflex Red Dot Sight

I purchased the 2 moa dot / 65 moa circle version for my Kel-Tec KSG, as it's advertised for shotgun use. When the product arrived I was extremely happy with the finish and clarity of the sight picture/ reticle. I had mounted it and proceeded to sight it in; this was easy enough. A few clicks in either direction and I was dead on zero. This was short lived however, and the front lens caved in from the shock of a 12ga prior to 30 rounds or so. Could be a fluke, as it seemed very well made; it could also be the KSG as the sight mounts above the barrel, forward of the bolt and chamber area.
