M4 is a nomenclature which was coined by the military. Is is a select fire weapon, with both semi-automatic and either burst of full auto firing modes.
Civilian legal lookalikes which fire semi-auto only can be purchased, and some (such as Bushmaster's) are even marketed under the name "M4". However, most of these "M-forgeries" do not meet the specifications prescribed by the Department of Defence for the actual M4 carbine.
The M4 can select semi-automatic fire or three-round bursts. The M4A1 can be switched from semi-auto to fully automatic.
A semi-automatic M4 derivative can cost as low as $800 from ImpactGuns. But for a civilian to acquire a fully automatic, military grade M4, be ready to spend up to $3000.
