This is a clever device that replaces the standard 88-gram CO2 Cylinder that powers 88-gram CO2 Rifles.
It uses two 12g cylinders in place of a standard 88g Cylinder, thus saving on the purchase of the expensive 88-gram cylinders.
It can also be removed from the air rifle once gassed, without any leaking, and then reinserted at any time.
You could use the adapter in two different guns and swap it when needed or take the adapter out when not using your gun and not waste any gas.
Supplied with eight 12 gram CO2 Cylinders.
