We have a great range of airsoft green gas, and we also sell red gas and even black gas for airsoft guns. Green gas is the most commonly used gas propellant in bb guns. If you are buying gas for a pistol with a plastic body, this is the one you want as red and black gas could be too powerful for your gun and damage it. Green gas also has an amount of lubricant in it that will help keep your gun maintained. red and black gas is dry so they will eventually dry out your guns seals and could make your mag leaky. but on the flip side red and black airsoft gas are more powerful and work better in cold temperatures. We have a big selection of airsoft gas's from the big brands like nurpol, swiss arms and abbey gas etc, and we have the cheapest green gas prices in the UK.
