its really personal preference , I prefer the lower 1/3 because when I use the RDS I dont have all that sight taking up the whole sight picture . and when I do need to use my irons my RDS wont be on anyway . Either way I have more sight picture thru the RDS with lower 1/3 . again its really personal preferenceI was planning to use "absolute cowitness", iron sight and red dot both centered on top of post. What is the advantage of using the lower 1/3?
If I use absolute cowitness, is a riser necessary? Is so, how much?
