Do you  really need a scope on your AR15?

Yes and No!

Yes: A "Quality" scope can be an excellent addition to your AR15 equipment list. For Close Quarters work.  a Red dot optics are hard to beat and for distance work a variable power scope can be dialed in for long distance shots. A quality optic will do you no good if not mounted to your AR15 with AR15 Scope Mounts equal to your scope. If you have a need or just want to add one, check out the scopes we have to offer.

No: If you do not use your AR15 for work or varmint hunting you most likely do not need a scope on your AR15. However since when does "need" have anything to do with it.
