[QUOTE="Shodown, post: 2776129, member: 35438"] The front sight does not necessarily block the view of a red dot. It will depend on how high the mount is for the red dot. If you put a red dot of some sort directly onto the flat top rail then yes, it might block it (depending on the red dot), but if you get raised mount (absolute cowitness or lower 1/3 cowitness) then it basically be in line with the front sight. Absolute cowitness = the red dot will be exactly in line with the front sight. Lower 1/3 cowitness = the front sight will be in the lower 1/3 of the red dot. I have an LMT 10.5" MK18 upper with an A2 front sight on my AR pistol paired with a Primary Arms microdot mounted to an American Defense lower 1/3 cowitness and I really like it.
