M4 is the select fire variat made by Colt. I think the designation A2 is a carry handle upper, A3 the flattop upper. Lots of companies use these designations to identify the configuration of there AR15's. (AR-15's being semi auto. )
Also the M4 and variants have a heavy, tapered barrel, for the military to attach a grenade launcher.
