Default New guy question about AR-15/M4 Classification

So, I am completely new to the gun/rifle world. My boss, who collects guns, has gotten me interested, so here I am. I have a question that I could probably research on Google, but I think you guys would probably explain it in laymen's terms. What are the differences between the AR-15 and a M4? I see pictures of the two and can't really tell much difference. Maybe I am an idiot or maybe I just have no knowledge of rifles. Thank you.

The AR-15 is the civilian classification of the rifle. It is a single fire weapon, almost always with a longer barrel to meet Federal Firearm Rules.

An M4 is the military version, is usually a short barreled weapon capable of fully automatic fire and single shot capability.

The lower receiver on the M4 has wider cuts inside the unit and there is an extra hole drilled laterally through the unit.

I will move this over to the correct section.

The M4 generally has a different cut barrel for a M203. I believe the military only uses carbine length M4s. I really cant think of anything else.

One other difference: the M4 is truly "milspec" and the parts that go into it must meet military specifications. ARs sold to the public, not the military, are of varying quality so you want to choose one of high enough quality for your use. Research is important if you need a rifle that will hold up under hard use. Just because an AR manufacturer claims their AR is milspec doesn't mean a thing. As you gather opinions here you'll find out which ARs work well and ones to avoid.

^ Probably the most important difference.
