Heavy scrap smg

Simple idea for a simple improvised/post apocalyptic submachine gun chambered in a rather large and heavy 45 acp cartridge instead of something smaller like 380 acp with a construction of simple materials like tubing, scrap metal and some scrap wood.

Chambering 45 acp.

Action type - open bolt full auto only.

Fire rate - 380-480 rounds per minute.

Manual of arms - To fire the heavy scrap smg the bolt has to be open as it is an open bolt smg, This is done by pulling/tugging on the grooved bolt extension on the firearms back that is connected to its bolt.

The gun has no safety features so keep your finger of the trigger until you are ready to shoot.
