This gun is a gas-operated, totally automatic rifle introduced by FN Herstal, a Belgian company in 2001. It uses a box magazine with a capacity of 30 rounds. The most unique feature is ejection of spent cartridge casings forward and to the right side through a tube that runs above the barrel. By ejecting them in this way, the gun is useful for left or right-handed users without modification and at a safe distance from the shooter’s face. Its effective range is to 1,600 feet.
FN also very recently introduced a civilian version of the F2000, the FS2000.
