Abstract: A disposable weapon system includes at least one ammunition round having a projectile, a propellant charge, and a casing strong enough to withstand the firing forces of the ammunition round containing the propellant charge and for securing and sealing the projectile. The disposable weapon system also includes a device for igniting the propellant charge of the ammunition round and a stick magazine having at least one through-bore complementary to and surrounding the casing of the ammunition round. The disposable weapon system further includes a barrel forward of the magazine that has a front end, a rear end adjacent to the magazine, and an inside surface forming a central bore aligned with the ammunition round within the magazine. The central bore forms a pressure tight seal with the magazine to allow the projectile of the ammunition round to traverse the central bore and exit the front end of the barrel.
