whats the difference between an M4 and a AR15? I know the M4 has a colapsable stock and shorter barrel. Any other differences?

I was thinking about that just today. How many people saying they have an M4 instead of saying ar15. But really I think m4 and I think auto fire. It's the latest updated military version of the carbine. Barrel has some different configuation, flat tops, flip up sights.......red dot scopes.......

ya but M4's dont come with all the gadgets on them. they come with stock sights, a short barrel, and a colapsable stock. The extra stuff is added on later depending on the job it's needed to do. I was actually wondering if any of the internals or anything like that are different.

no internals that I know of except, lower cutouts and barrel scallops that help bullet feed where these parts mate up. The other difference is the flat top. I don't think there are any other deffernces other then the cuts/shape of the barrel.

Don't know how accurate this is or if it helps but I'll throw it in anyway.
