Good to know about green gas.
When owning a airsoft replica what works on green gas, you need to keep in mind that the performance chances when the temperature drops or rises. So it is possible your replica won't be able to shoot with your standard green gas when it is cold outside. When this is the case you can use another green gas like Nuprol 3.0, This kind of green gas performs better in cold temperatures.
