This is what I have the 3-9 version of that scope mounted in and it works pretty well. They are around 100$ at local outlets. http://www.leupold.com/hunting-shoo...ystems/mark-2-ims-1-integral-mounting-system/
run what was recommended at the link above. or make sure that the rings put the centerline of the scope tube at 1.4-1.5" above the rail. thats the height needed for the flat top ar, unless it has a raised rail on it.
What's the point of this? Why not leave the question up, so if others have the same question they can get it answered with a search instead of posting and waiting?
