M4A1

Overview
The M4A1 is pretty much a variant of the M4 series of carbines, which is based off of the M16 assault rifles. Unlike the normal M4, the M4A1 is capable of semi-auto and automatic fire, while the original M4 is limited to semi-auto and burst.

Ghost Legacy
Ghost II was originally planned to use the M4A1, however, due to a game-breaking bug, Ghost II was canceled and the M4A1 never made it in.
