Power your airsoft guns with Green Gas and CO₂! Whether you run gas blowback pistols, rifles, or SMGs, we’ve got the fuel you need for consistent performance. Green gas provides smooth operation and often includes silicone oil to protect seals and extend the life of your gun, while CO₂ cartridges deliver higher pressure for stronger recoil and reliable year-round use — even in colder weather. Both options are essential for serious players looking for realism, durability, and power. Shop East Coast Airsoft for the best selection of green gas and CO₂ at competitive prices and stay game-ready. Do note, these items cannot be shipped online and are ONLY available for in store pickup!
