But I know for a fact that I can outshoot my red dots with my irons on a slow fire black bullseye from a rest or prone unsupported. Irons allow for as much precision as you know how to get from them--and that can be quite a bit if you know what you are doing.
Now go to a more practical timed run and gun application the Red Dot wins because its accurate enough but its also very quick and somewhat forgiving at 50 yards and under.
I am considerately more precise with iron sights out to about 150 yards when I have a high contrast target for which my sights are regulated. Under those circumstances, my irons are more precise than even magnified scopes! It is when the targets are changed to something that my irons are not or cannot be finely regulated for that magnified optics begin to allow for more precision.
When time becomes more critical, a daytime illuminated 1.5-5 or 2-7 Leupold scope is lightning fast and quite accurate out to 300 yards.
