Ive recently fed my curiosity to get a ar15. I just had a question about barrel types..

I see some that are flat all around like this:

and some that have a 1inch give or take portion that is smaller and more skinny like this:

What are the differences and uses of each type? what are their pro and cons?

Well im no AR expert by any means, iv been doing some research cause im loking to purchase one this summer. But that cut (if im not mistaken) is to mount accesories, like a granade launcher to. (only accessory i can think of).

if im wrong pelase correct me, this might be stupid, but i want a barel with that cut cause I think it looks cool, lmao. dumb reason but whatever. lol.

the only difference between the two really are how much they weigh. I can't speak as to whether it has anything to do with mounting anything.. if it does, that'd be the first I've heard that.

The thicker barrel is heavier... the one with the cuts in it are lighter.. and more preferable for the average use of an AR.

You have the heavy barrel, the R-4 heavy, and the R-4 lightweight profile.

here are the R-4 barrels. http://www.rockriverarms.com/item-detail.cfm?ID=AR0202ASY&storeid=1&image=bblr407.gif&CFID=38975990&CFTOKEN=29596276
