FN F2000

The FN F2000 is a gas operated, fully automatic 5.56×45mm NATO bullpup assault rifle, designed by FN Herstal in Belgium. It is fed from STANAG box magazines with a 30-round capacity.

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 a Picatinny 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.

One of the modules developed for the F2000 system is a proprietary lightweight 40mm underslung GL1 grenade launcher that uses standard low-velocity 40×46mm grenades. The launcher is a single-shot breech-loaded reverse pump-action weapon with a barrel that slides forward for loading and unloading, locked by axial rotation of the barrel.

The grenade launcher comes with a basic flip-up ladder sight, but it was intended to be used with a specially designed optoelectronic fire control system designated FCS, developed in cooperation with the Finnish company Noptel.

The aiming module is installed in place of the standard optical sight and becomes the weapon’s primary sight when mounted, but its main purpose is to accurately determine and indicate the range of a grenade target. The module is powered by a 9 V battery pack, installed in the stock, behind the magazine well. The power pack is also intended to power any other tactical accessories or systems that could be introduced. The FCS integrates a low-power laser rangefinder (precise to within ± 1 m), a day-time aiming channel with an electronically projected reticle, a measured range display reading and a diode elevation adjustment indicator. The F2000's aiming module grants a +2 to Shooting rolls with the F2000's grenade launcher.
