Airsoft Gas & CO2

Gas guns run on a propane-based gas (often sold as green gas, in several pressures) or on CO2 capsules. Use the gas your gun's maker recommends: a stronger gas than the gun is built for wears it out faster.

Gas pressure falls as the temperature drops, so gas guns lose power on cold days.

The catalogue lists 34 gas and CO2 products; the brands with the most are ASG (ActionSportGames), Nimrod, Nuprol, Umarex and Specna Arms.
