Functioning Panzerfaust

The panzerfaust 60 was a WWII German anti tank weapon with a warhead that shot from a metal tube and lobbed itself onto enemy armor and exploded.
The most defining feature about the weapon was that it was recoilless, meaning that the user would not be knocked back by by recoil from the warhead launching. The weapon was meant to be fired once and discarded where the user would grab another one and fire that.
This version is a functioning model very similar to a potato gun and able to be reloaded an unlimited amount of times.
