General question a few of my infantry buddies and I were sitting around talking about last night, and I'm looking for input on. The M16A2 had two apertures on the rear sight. the 0-2 was 0.200" and the unmarked one I believe was 0.052". On my new M4, the BUIS I was issued only has one aperture and it measures 0.075". I know that the smaller apertures allow less light to enter the eye, so in low light situations we always used the 0-2. Now I have an aimpoint and aside from zeroing my BUIS never use it, but why did the army choose 0.075". Is smaller more accurate, or does it mearly decrease the ability of the shooter to misalign their sights? Is 0.075" just some sort of compromise?
Thanks in advance,
