This red dot comes with all the original markings and the red dot works great. I don’t have NVGs, so I can’t test the IR settings. I usually turn the dial to position 9 for a clearly visible red dot.
The high mount that came with it was not as shown on the photos. It is the same shape, but with screws instead of a clamp mount, and different markings. The marking I got was from Daniel Defence, which also looks very good.
