Air Saver Adaptor For Airguns, Airsoft, Paintball

The 88 Gram CO2 Saver Adapter saves you CO2 because it lets you remove an 88g, 90 gram CO2 cartridge from an airgun without having the left over CO2 leak out.

The valve on the adapter closes when it's removed from a gun, so you can take it off and still have CO2 next time you want to use it.
