Now, it was mounted to the handgun via dovetail mount instead of being milled in; I'm not sure if that matters for durability purposes or not. Others can chime in on that aspect since I'm pretty much done with this experiment for now. Hopefully you have better luck than I did, but if you don't, rest assured that Insight will take care of you. Each of my 4 replacements was sent free from Insight after returning the broken optic.
That's the sort of feedback I was looking for. Albeit not what I was hoping for. Thanks man!
