IMHO, you would be mixing apples w/ oranges. the dial-a-range is for single aim point devices. In other words a single red dot or single xhair scope. The three dot red dot is for three ranges already, usually around 20,30, and 40. The dial-a-range is also called the dial-a-rage as the rope cockers tend to want to move the dial on ya. Some guys have pinned it solid and use multi aim point devices like a compensating scope or three dot red dot. Hope this helps.
