I have 3 different china made reflex sights. all work great in the sunlight. Also all of them work for target acquisition cause I know how to set the sight up and how to tune a gun so it's useful.

That being said, a reticle with a circle is going to be more useful than a dot. Airsoft, even well tuned will shoot a cone, to a certain extent so do real steel but you're talking about groupings in fractions of an in vs inches at airsoft ranges.

With a big circle that's properly zeroed on a sight that's both eyes open, you can just put the circle on target and your bbs will more than often land there... if you've zeroed it properly. The way I've done it is that at max effective range for my gun, where they start dropping out of the circle is balanced with the widest point of spread that my shots will make. That way anything closer than that I know will land in the circle reliably.

Beyond that if the guy doesn't fit in the circle I know my rounds will fall short and I need to start holding over, and I know immediately my rounds may be off line from the circle, so those shots are carried on the wings of little fairies and pixies.
