On my plinking gun (the one I'm teaching my son rifle with) it is the included Magpul sights only.
Optics can offer many different advantages, depending on the one used. More leeway in eye position/cheek weld (or lack thereof), faster (no lining two thing up), usable even in very low light (red dot/holographic/illuminated reticle), magnification, light gathering, etc.
A good optic that matches your use for the gun is usually a good investment
