*the information below does not necessarily reflect every AR-15*
-M-4 has a 14.5" barrel, making it a title II firearm.
-Carbine AR-15's have a 16" barrel, making them legal. They look like an M4 with a little extra on the end.
-A1 upper receivers have a carry handle and can only be adjusted for windage. A1 handguards are triangular in shape (think Vietnam era M-16).
-A2 Upper receivers look like A1's, but the rear sight aperture has it's own housing that can be adjusted for windage and elevation. A2 handguards are more round than A1 handguards.
-A3 uppers only have a rail on the top for mounting optics.

www.ar15.com has LOADS of information on the AR-15. If you can find one, I would suggest picking up a DPMS catalog and read that. It's 3/8" thick of pure EBR goodness, and it's not the only catalog out there.

The bohica rocks. Gingerbreadman gave good info for ya to look at also. As for the .50 BMG Bohica...they weigh the gun down more but shooting them is pretty easy. If you have ever shot a heavy turkey load from a 12ga shotgun its very similar, the 50 might be slightly more potent but the report is far more extreme than that of a shotgun. My suggestion to anyone with an AR...buy the bohica and get a press for .50 cal reloading.

This thread describing A1, A2, A3 was right below yours. Also, the search function works perfectly fine. Try it...there is plenty of AR information to go around.
