Editing FN F2000 (section)

===Features===
The F2000 is a gas-operated, fully automatic and ambidextrous bullpup rifle. Both the safety system and trigger mechanism were adopted from the [[FN P90|P90]] [[personal defense weapon]]; the selector toggle is a rotating disc located below the trigger. The fire selector doubles as the weapon's manual safety and secures the firearm against accidental discharge (the selector/safety disc has 3 settings: "S" safe, "1" [[Semi-automatic firearm|semi-automatic]] mode, "A" fully automatic fire). The "safe" setting disables the trigger. The hammers, group pins, and springs are steel while all other components are nylon injection molding. The shell of the rifle is made of composite materials.

The F2000 is fed from standard [[NATO]] box [[magazine (firearms)|magazines]] ([[STANAG magazine|STANAG 4179]]) with a 30-round cartridge capacity using [[5.56×45mm NATO|5.56×45mm]] ammunition. The magazine catch/release button is installed symmetrically in the pistol grip, in front of the magazine; the magazine catch is operated by an oversized actuator useful when wearing [[NBC suit|NBC]] gloves. The F2000 is not configured from the factory to have a drop-free magazine system due to the friction from the removable dust gaskets. The magazine needs to be pulled out manually.

The rifle does not have a hold-open device; the bolt does not stay back after the last round is fired. The charging handle is placed on the left side of the receiver, just above the hand guard, and can be operated by left-handed shooters. There are no access points for the possible ingress of dirt or debris; the charging handle slot is sealed.

The weapon's primary sight is a telescopic sight with a fixed 1.6× magnification (the reticle also enables use in low-light conditions) contained in a plastic housing above the receiver (mounted on the MIL-STD-1913 rail), the secondary sight is a non-adjustable fixed notch and front blade, molded into the optical sight housing cover. The sight cover and sight module can be quickly removed to reveal the Picatinny rail.

The rifle's chromed hammer-forged [[steel]] barrel is stated to retain accuracy after 20,000 normal (non-sustained) rounds. The barrel also features a [[flash suppressor]] with an angled cut at the tip which directs the muzzle blast upward, compensating for muzzle rise. The F2000 has an optional [[bayonet]] lug mounted near the muzzle, and an adjustable gas regulator with two settings: "normal" for standard ammunition meeting NATO specifications, and "adverse", used to send an increased volume of gas into the system to ensure proper functioning when fouled or when using low-pressure ammunition.
