Correct, with my buis flipped up, the 1moa dot was sitting on the tip of the front post(touching if not slightly covering) in the center of my aperture.
Unfortunately this is without a qd mount, but I figured if I can see my sights through it, who cares. I guess the only way it would hurt is if I got paint or something on my lens. haha.
I also have high cheek bones and I felt that the optic on the rail was perfect for me. Many people use risers for the lower third cowitness but I liked it fine without.
Edit: If you prefer lower than absolute, you may want to look into an Aimpoint T1 or something. I dont know the height of different risers for it but I can tell you that it would be way too low on the rail. I have tried it out of curiosity.
