FN FS2000 Standard

Intended for civilian ownership, the FS2000 is a 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 muzzle brake 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. Measurements on the stepped barrel's rifling were as long as the non-stepped barrel, revealing that the stepped barrel is not simply a shorter F2000 military barrel with an extended muzzle brake which is similar to the PS90. A variant of the FS2000, called the FS2000 Standard, is equipped with the factory F2000 1.6× magnification optic and sight cover. It does not contain the grenade launcher computer.
