HOW TO REFILL A GAS AIRSOFT GUN

Updated: Jun 25, 2021

GREEN GAS OVERVIEW

The term Green Gas is commonly misunderstood as Greenhouse Gas which refers to water vapor, carbon dioxide, methane, or ozone. However, in airsoft, the chemical composition for airsoft green gas is very different.



Just to reiterate, a magazine is the part of your gun dedicated to holding the plastic BB pellets which are used as the primary ammunition in airsoft skirmishes.


For GBBs, magazines are also used to store the propellant gas used to provide velocity to each shot and, ultimately, fire the BBs down the gun’s barrel to hit your target.



HOW TO FILL YOUR GUN WITH GREEN GAS

It's easy to fill your gun with green gas, as with most gas airsoft replicas have the green gas reservoir in the magazine. Green gas bottles have built-in adaptors, making them easier to insert into the mag. Once it's in, charge for five to eight seconds then stop.



First things first, remove the cap from your gas canister and make sure you’re holding it upside down as illustrated below.


This stage is important as the gas is actually stored in a liquid state and holding it in this position will help facilitate a much smoother draining process into the magazine.

Next, insert the nozzle into the fill port whilst ensuring both the gas can and the magazine are correctly aligned with one another.


The can should not be off to one side but, instead, held in parallel to the magazine in order to provide an optimum transfer process and avoid snapping the nozzle.


Now all you need to do is simply apply pressure down onto the gas bottle for about ten seconds (ish) and then release – you should hear a quiet ‘hissing’ noise but don’t worry, this is perfectly normal.


Using an intervallic method helps to acclimatise the gas and the magazine to the change in temperature and will allow more gas to be held in each magazine.


Repeat this process in ten second stages until the hissing noise becomes louder and you begin to see gas leaving the magazine. At this stage, the magazine is completely filled with gas and ready to be used in your .
