Last nite I got my CASM mounted so I could raise the EoTech up off the op rod area and rid myself of it trapping the brass. Well, it's like sitting a turtle on a post... Way too high! No cheek weld to speak of. I can see something else happening on that setup just don't know what yet.
My other CASM works great on my Standard using low rings toting a 3-9x50. Very solid mount.
