It is capable of powerful armor piercing semi-automatic, burst or automatic firing modes. It also comes equipped stock with an under-barrel grenade launcher that makes the weapon more difficult to wield, but capable of dumb firing up to six grenades one at a time that detonate on impact with a hard surface with a wide blast radius. The under-barrel launchers uses the Explosives skill.
