I want a QD mount that will allow an ACW with my flip-ups. Front sight post is right at 1.25" and the dot of the T-1 is about .75" in the factory mount (from the top of the mono-rail). So, I guess I need about .625" of riser. I don't see any listed with absolute heights. The ADM CAS-V looks about as close as anything. Any help or ideas?
