Too much time on my hands, so I dusted off my 180.

Got me thinking about a hipac mod. Does anyone know if its been done or if they would make one? Now that I think of it, a few of the suppliers of old school parts sell an extention co2 tube so I wonder would it hold up like a 2260 tube for a few really hard shots. I think it would be cool to have a duel fuel carbine, one thats even a little handier than a disco. What do ya'll think?
