I'd like to thank Enone for the great design. The lower mount dimensions fit like a glove. The rail portion also works like a charm. For this I made it much lower profile. The height of the original cramped my style. So this one doesn't sit as high up as the original. Here you can still use the iron sights if you take off your optics, and I find less compensation needed at longer range with the optics. I also beefed up the thickness of the clamp fingers and removed some upper material so it prints faster and with less material.
