How to Convert a CO2 Pistol to Green Gas
Environmentally sound with green gas (a gun image by timur1970 from

Target pistols that are able to fire as fast as the trigger is pulled use CO2 gas cartridges to "power" the weapon. You can replace the CO2 gas cartridge with a more environmentally friendly "green gas" cartridge, providing that the target pistol's design includes using "green gas" as an alternative to CO2. Converting a CO2 target pistol to use green gas only requires the purchase of green gas cartridges and a green gas magazine that will replace the CO2 magazine the target pistol is currently using. Adult supervision is required should the person converting the target pistol to green gas be a minor.

Skill level:

  8. 8

    Insert the green gas magazine into the bottom of the target pistol's handle. Push the green magazine up into the bottom of the target pistol's handle until it clicks into position.

  9. 9

    Go into your backyard. Cock the firing mechanism of your target pistol that will now be using green gas instead of CO2.

  10. 10

    Aim the target pistol at a tree or rock that is free of any person or object that could be damaged if the projectile misses the target. Squeeze the trigger to fire the projectile. Wait as the target pistol is reloaded using green gas.

Tips and warnings

  • Be sure that the airsoft gun being used with green gas has been designed to accept this type of gas--otherwise the airsoft gun's internal components will be damaged.
  • Never aim any kind of weapon, real or pretend, at a person.
