(Alternate History) Homemade Sub Machine Gun

(Fair warning: there is some stuff here about Gun Politics)

An example of a Homemade Sub Machine Gun. Such weapons are from time to time in the hands of criminals by police in the US, either Local, State or USFP (United States Federal Police). Such weapons come in a variety of shapes and calibers, this one is 11.5mm Browning, which is the most common. Other common calibers include 9mm Inter-Atlantic, 8mm SN (Shin-Nambu) and 7.62 Tokarev are also common cartridges used by these weapons. It also has a home made magazine for 24 rounds. This one was found in the use of a fringe political group called the Brotherhood of Liberty, one of several extreme groups which subscribes to a number of rather reactionary ideas based around the Jeffersonian Ideals, being against urbanization, the Federal Government and for "bringing back America to the ideals of the Founding Fathers", which generally translates into racism and repealing numerous amendments in the US constitution, among them being the 16th which was passed in 1877 after the brutal Uprising of 1876( in which a number of Confederate Veterans and their associates in the South launched a series of large scale attacks against federal troops, federal officials, northerners engaged in reconstruction, black people (their main target) and white southerners who they saw as collaborators, killing some 30,000 people before being contained, most of which were civilians) and repealed the previous 2nd Amendment.

Private ownership of automatic weaponry has been a crime since 1919 in the United States after the development of sub machine guns and light machine guns during the great war. Even so, some criminal and terrorist organizations still manage to acquire such weapons on the black market. Black market weapons do get into the US, but there are often complications with this. Often when dealers in the black market will manage to get in a shipment of guns of a specific caliber to an area, they do not get the ammunition for them. Several criminal organizations are involved in the underground manufacture of weapons and ammunition, either to be sold on the street or to be used by the criminal organization itself. Most of the guns that are made are pistols, though compact Sub Machine Guns are also made. Occasionally rifle caliber carbines are made, but these are pretty rare. These weapons are generally functional, but are usually of very poor quality construction. This is often made all the worse due to improperly stored ammunition, low quality home made ammunition and a lack of proper maintenance. More often than not, the more serious criminal organizations will avoid making or using them for this reason. As well as avoiding unwanted heat for illegal manufacture of firearms. Several times, most notably in 1986 and 1998, there had been police busts in which several hundred of these weapons have been found. These finds have been accompanied by the release of a number of low budget action movies involving terrorist armies of fascists rising in the US in the following year.
