Chambered in 5.56x45mm NATO/223 Remington, the FN FS2000 CQB is a civilian legal, semi-auto only variant of the proven F2000 selective-fire bullpup carbine that offers an integrated MIL-STD 1913 top and bottom mounting rails and emergency backup folding sights. The FS2000 carbine is gas-operated and uses a rotating bolt lockup for reliability and greater accuracy. Its 17.44 in cold hammer-forged MIL-SPEC barrel is fitted with a muzzle brake. Fired cases are ejected through a forward port away from the operator. The matte black thumbhole design polymer stock is ambidextrous. Models with 10- or 30-round detachable box magazines (DBM) are available.
