Never used the sights for the airsoft, I know where it will hit before it gets there but the wind has a lot more effect than the sights have had so far.
I shoot one or two shots followed by a short burst, since we can se the bb it is not that hard.
Iron sights! For our ranges and area we can operate in!
Scopes are good for distance recon only! So I can see you big deal the gun don't shoot but 200 feet.
Red dots need batteries and they break.
If I had to set down in stone how I do it "both eyes open, sights over lapping sight picture" right eye dominant, like pistol combat shooting, bring the sights and gun to the eye, and tons of practice,is what it amounts to.
You must know where 'it' will hit before you pull the trigger. I shoot with in an inch to two max, at 40-60 feet but I spend all day shooting cans and 2 inch fence posts at our propety, so people are not that hard to hit.
