What's the difference between reflex optics (MOS) and standard iron sights?

Optical sights: Within the reflex optics, you look through the reticle and focus on the target and alignment of the dot.

Standard sights: With standard iron sight shooting, you align the front and rear sight with a hard focus on the front sight.

Optical sights are popular in competitive shooting and are becoming increasingly popular for home defense and target shooters.
