"Sten"

"Sten" is a generic Nomad term for any homemade/modified submachine gun, in honor of the original Sten gun. The stats given are for a typical example, but they range from very reliable to almost-certain-to-blow-off-a-shooter's-hands. They are available in several different configurations, and may be chambered for any ammunition from .22 Long Riffe (1D6), through 9mm Parabelfum (2D6+1), to .357 Magnum (2D6+3) and 12mm Caseless (4D6+1). Stens are also known in streetpunk culture as zipper-guns.
