The FAL is a top-notch assault rifle. Although it lacks the range of the AK-112, a burst from the FAL will actually deal damage, unlike AK AP ammo without an AP fix patch, or AK JHP ammo with a fix patch, which both won't. The 7.62mm rounds it uses are pretty rare, though, so burst at your own discretion.
The FN FAL is a battle rifle designed by Belgian company Fabrique Nationale d'Herstal (FN prefix) after World War II.
The rifle is based on a gas-operated mechanism. Selective fire modes were available when it was initially designed around intermediate power cartridges such as the German 7.92x33mm Kurz and the British .280 (7x43mm). Once NATO standardized on the more powerful 7.62x51mm round the FAL was successfully adapted to chamber it, but the selective fire capability was usually removed as the recoil proved uncontrollable when set to fully automatic.
