Shooting with irons is a lot of fun no question, and every AR owner should know how to hit the broad side of a barn using them.
I have back up iron sights on all my rifles, but all of them have a Aimpoint or magnified optic. You cannot beat the speed and pin point accuracy of red dots, and with Aimpoints failure is very very rare. Can't say that about most other brands of RDS, though.
