Walther Co2 88gram to 12gram conversion kit
This kit has two major advantages for people using the 88gram Co2 to power their Co2 guns
This convertor allows the use of 2 12gram Co2 bulbs instead of the 88gram, which actually works out cheaper
The end of the adaptor has a valve which prevents Co2 from escaping. The valve does not open until the adaptor is screwed into the gun and it closes when it is removed. This saves your gas. You could use the adaptor in two different guns and swop it when needed or take the adaptor out when not using your gun and not waste a 88gram´s worth of gas.
