Paintball CO2 Fill Device

The CoolFire Trainer Paintball CO2 Fill Device is compatible with every Trainer Barrel and works with Paintball CO2 Tanks. It screws directly onto the CO2 Tank to allow re-filling of the barrel.

IMPORTANT: A CO2 Fill Device is needed to make the CoolFire Trainer Barrel function. If you do not already own a CO2 Fill Device, please select one of the available Fill Devices.
