Green Gas designed for use on gas powered Airsoft pistols, Rifles and Shotguns. The gas comes in a lightweight aluminium can and has a heavy duty metal nozzle meaning it won't snap. 

Full description


This green gas can comes sealed with a pull tab so you can guarantee the gas has not been used before. This type of Gas is slightly more powerful than standard Airsoft Green Gas by other companies, and as such is more suited to Rifles, Shotguns and Pistols with an Alloy Slide. Unlike other comparable Green Gas, Ultrair does not have lubricant in its composition, meaning improved accuracy at a small cost of performing slightly more routine maintenance to keep your seals fresh. This ASG green gas is perfect for all Airsoft gas gun users, providing a good and consistent gas level even in variable temperatures.
