CPS Custom Assault Rifle

CPS Custom Assault Rifle: "I initially built the pump out of CPVC. With the correct o-rings and some duct tape I managed to make it work with a wooden stick. Unfortunately, even if the pump shaft was more than one feet long, it only had a volume between 30mL and 40mL, which isn't much for a homemade. At least it was on par with regular CPS Super Soakers."
