The FN F2000 is a modular weapon system; its principle component is a compact 5.56x45mm NATO-caliber assault rifle configured in a bullpup layout. The F2000 is a selective fire weapon operating from a closed rotary bolt.
The rifle consists of two main assemblies: the barrel receiver group and the frame, joined together with a pin located above the oversized trigger guard. The barrel group has an integral MIL-STD-1913 Picatinny rail used to mount optical sights. The frame or lower receiver contains the trigger group, the bolt and bolt carrier assembly, return mechanism and magazine well. A removable handguard is installed in front of the trigger which completes and encloses the trigger guard.
F2000 Tactical
The F2000 Tactical railed variant is similar to the standard model, but it lacks the optical sight, and comes instead with an extended top receiver MIL-STD-1913 rail with flip-up iron sights.
FS2000
The FS2000 is a civilian-legal, semi-automatic version of the F2000 that first became available in June 2006. The FS2000 Tactical model is equipped with an extended barrel with a permanently attached flash suppressor and a 1:7 in right hand twist rifling rate; the bayonet lug was not included on the FS2000 rifles. The lower hand guard can be removed in the same manner as the F2000 to accept the same variety of accessories. It comes with a Picatinny rail optic rail along with backup iron sights. The rear flip-up National Match-sized aperture is adjustable for windage, while the removable front sight is adjustable for elevation. A small number of the early models featured a stepped barrel contour as well as a demilled bayonet lug. A measurement of the stepped barrel's rifling was as long as the non-stepped barrel, revealing that the stepped barrel is not simply a shorter F2000 military barrel with an extended flash hider.
