Yes, I originally had this sight mounted to the top of the carry handle but I now have the carry handle removed with the sight mounted right to the flat top. I purchased a flip up rear iron.
Yes, my rear iron and the holo sight are set up co-witness. If the battery ever fails on the optic, I will already be looking through the irons anyways.
My sight picture with this setup looks like a normal iron sight sight picture with the crosshairs of the optic kind of floating in the middle and lined right up with the irons. I absolutely love it this way. Everyone else who shoots it also seems to really like it as well.
