Speed-Y-DOF-1's nut launcher
Another example of improvised weapons, this was a pair of copperlyke pipes with a balloon duct taped to one end of each pipe, with a laser pistol mounted underneath. It could launch small items, like nuts.
The pistol grip's barrel mount was inaccessible without disassembling the whole thing, which made changing barrels a problem.
This was destroyed when the Tsar Nuclear Device detonated.
