Technically an M4 is a military weapon capable of fully automatic fire, an AR-15 is semi-auto. In practical terms, however, a civilian M4 is just a short barrel carbine version of the M16/AR-15 platform.
"The whole of the Bill (of Rights) is a declaration of the right of the people at large or considered as individuals.... It establishes some rights of the individual as unalienable and which consequently, no majority has a right to deprive them of." (Albert Gallatin of the New York Historical Society, October 7, 1789)

"A free people ought not only to be armed and disciplined, but they should have sufficient arms and ammunition to maintain a status of independence from any who might attempt to abuse them, which would include their own government." - George Washington

It's pretty much like Jpyle said. The old Armalite company designed the AR-15 (which stands for ARmalite 15 - their 15th gun design) then sold the manufacturing rights to Colt. The first rifles Colt supplied to the military were stamped Colt AR-15 but later when the military accepted the rifle it was renamed as the M16. Those first AR-15s were full auto but today the term is a generic one for civilian and LE semiautos.

Anyway you can call your Stag an AR-15 or M4 or M4gery if you like. And parts designed for any of those should work in your rifle. Except for legal reasons you can't get parts that would change your rifle to full auto or burst (or a few other controlled parts).
