The F2000 is a 5.56x45mm NATO bullpup rifle, designed by FN Herstal in Belgium. The F2000 made its debut in March 2001 at the IDEK defense exhibition held in Abu Dhabi, in the United Arab Emirates, and is still used by various countries today.
With a modular weapon system, its principal component is a compact 5.56x45mm NATO-caliber assault rifle in a bullpup configuration. Gas-operated and fully automatic, the F2000 is a selective fire weapon operating from a closed bolt. Both safety system and trigger mechanism were adopted from the P90 personal defense weapon. Using a unique ejection system, the F2000 is a fully ambidextrous, bullpup rifle with the spent cartridge casings being ejected forward and to the right side of the weapon through a tube running above the barrel.
