I'm looking for a set of QD rings for a flat top AR. The scope mount that came with the rifle doesnt allow the scope to be mounted far enough forward for proper eye relief. I like to have the scope sit about where the rear iron sight is, with my head forward. I also dont want to get to high with the rings. I was looking at the A.R.M.S. QD rings, but they dont appear to have one with a cantilever. I've seen pictures of rings similar to this, (one standard and one cantilevered) but cant find who makes them. Any links or suggestions? TIA.
