1. This NEW WA M4 GBB Airsoft Gun assembly is extremely sophisticated. DO NOT attempt to dissemble the gun without consulting us. No Guarantee will be honored if the gun has been dissembled. 

2. HFC134a airsoft gas is recommended. Although HFC22 Green Gas/Top Gas can be used for WA Gas Blow Back, it is NOT RECOMMENDED because the internal mechanism is designed for HFC134a airsoft gas. It may not withstand the prolonged high pressure of higher power gas. Please note No Guarantee will be honored if the gun has been fired with HFC22 Green Gas/Top Gas.
