The Saab Bofors Dynamics-produced Carl Gustaf recoilless rifle or MAAWS stands as a highly versatile, man-portable anti-tank and anti-structure weapon system. The most modern variants fielded by Swedish rifle companies have been fitted with the Swedish Aimpoint sighting system. The Gustaf M4 anti-tank weapon system, can be fired from the standing, kneeling, sitting or prone positions, and a bipod may be attached in front of the shoulder piece. An operating handle called the "Venturi lock" is used to move the hinged breech to one side for reloading. The Carl Gustaf Recoilless Rifle is renowned for being one of the loudest weapons on the battlefield. Because of these features, the Carl Gustav gun is defined as Swedish punch.
