As stated my peep was set 5.5inches from my Dloop and I was NOT able to get maximum range with this site. When I figured that out my confusion stopped and I was able to shoot 3 inch groups @ 90 yards.
I moved my peep to 6.5 inches and haven't looked back!
Cons: My peep was only at 5.5 from my Dloop
