The Carl Gustaf recoilless rifle earliest prototype was built in 1946, and it has been used in many countries for more than 70 years through a series of derivative models. This is due to the light weight and low cost of its body and shells. It can also be combined with a variety of shell types, allowing Carl Gustaf the versatility to be used in modern changing battlefields.
The U.S. military named the Gustav recoilless rifle as the "Ranger Anti-tank Weapons System" (RAWS), and the M3 Gustav recoilless rifle prototype displayed for the 1st time in 1991. Shortly after, Bofors introduced the Carl Gustaf M3 version. The improvement on its predecessor was to reduce the weight of the launcher body: The inner lining of the launch barrel, including the rifling, was made of thinner steel. The reinforcing material of the external structure is made of lightweight carbon fiber and epoxy resin, and all parts that do not need strength are made of aluminum alloy or plastic, all of which greatly reduces the weight of the original transmitter by about 6 kg.
