@ Mr. G36!
Geez, I'm so behind the airsoft times. I've only ever used a bare RDS. Does iron sights + RDS help with aiming? I would think, if the red dot is on target, you're gonna hit it, whether the iron sights are there or not.
However, I really only have experience with bare iron sights or a good scope. =P
This is why I love this forum.
