NUPROL 2.0 Mini GREEN 85g Gas. Green Gas used to fill Airsoft Gas Blowback Pistols and Weapon Magazine created by NUPROL and designed to be cleaner, with a higher performance than WE Europe’s old Green Gas. The gas comes in a smaller bottle than the traditional NUPROL 2.0 Gas, which is designed to fit into pouches and pockets for easy carrying during an Airsoft Skirmish. Give your FPS a boost, whilst keeping everything running smooth and clean. The Gas is an excellent all year round gas from NUPROL. This gas is a must have for any Airsoft Skirmisher who has a Gas Blowback Pistol, Carbine or Rifle and wants to re-gas their magazines in the field, allowing them to play for longer without having to go back to the safe zone to re-fill magazines.
