They still are. You asked for optics choices. Standard iron sights are always the back-up. Get a mount where you can use the iron sights along with your optic. Rather difficult sometimes for a civilian to properly use the iron sights available on a standard or mil-spec AR. This is obviously where many manufacturers make their money. Iron sights were good out to 500m back in the day I remember. Things change just like we do.
I'm surprised by the number of people voting for irons. I figured red dots would be the run away winner.
