1/2 MOA clicks and a 50 thou aperture - that's pretty darn nice for BU sights!
Of course, you'll probably want a bigger hole for SHTF type shooting.
At what distance from your eye is the front sight hole 8 MOA? 8 MOA is a pretty good fit for those HP target bulls. They are 6 MOA.
I havent measured, but somewhere around 30". If i were to guess. Whatever it is, its very comfortable and easy to get behind. In all, im pretty happy with the sights. Also, the rear peep is removable and interchangeable. With it removed, it allows for quicker target acquisition, but is less precise. For a SHTF situation it would work fine. I was watching a video on these sights and guys were getting on targets almost as fast and just as accurately as a red dot. Of course red dots are better in low light, but these work well, for what they are. I also believe they were designed for 3 gun competition. The sizes of aperatures im using are more for precision, rather than speed.
