The Thompson was also known informally as: the "Tommy Gun", "Trench Broom", "Trench Sweeper", "Chicago Typewriter", "Chicago Piano", "Chicago Style", "Chicago Organ Grinder", and "The Chopper".
The Thompson (named Thompson submachine gun by the maker) is an American submachine gun, invented by John T. Thompson in 1918, that became infamous during the Prohibition era. It was a common sight in the media of the time, being used by both law enforcement officers and criminals. In 1938, the Thompson submachine gun was adopted by the U.S. military, serving during World War II and beyond.
The Cyberguns M1A1 is almost completely metal. Only parts that are not metal are the stock, pistol grip and front hand guard. Those 3 parts are very good looking wood imitation parts. Due to license that Cygerbun owns, there are also authentic markings on the gun which seal the whole deal with this gun being a genuine SMG of the WW2.
Internally the gun is full of quality parts. The gears are steel mixed together with metal bushings. Of course everything is Marui compatible.
This package comes with a gun, magazine, battery and charger.
