The standard F2000 comes with a plastic forward handguard and an optical sight with 1.6x magnification. The sight cover and sight itself can be removed to reveal a Picatinny rail. The forward handguard can be removed to equip a variety of accessories such as laser aiming modules (LAM), 40 mm grenade launcher with push-button safety, 12-gauge shotgun, M303 less-lethal launcher, or the triple rail found on the F2000 Tactical. The optical sight can be replaced with a special computerized fire control system designed for the 40mm grenade launcher. The fire control computer makes firing regular grenades much easier, though it cannot fire smart grenades. There is an Israeli system that uses the M203 and computerized sight to fire 40 mm airburst grenades. Neither of these should be confused with the 20 mm and 25 mm grenades of the U.S. OICW program.
