The FN FAL is a battle-rifle designed by FN Herstal. It is chambered in 7.62x51 NATO, and has been widely used. This variant is equipped with a AN/PVS-4 night vision sight (non-toggle-able i.e: cannot be switched between night vision and normal crosshairs), only available from helicopter crashes. This weapon is one of the rarest finds in the game but, because of its optics, this weapon can only be used at dusk/night/dawn with any precision while firing.
This weapon will likely be removed in the future, and a AN/PVS-4 scope attachment added instead.
