Hostile Green Gas

Hostile Green Gas is a premium, high-pressure propellant engineered to keep your gas-powered airsoft guns firing harder, faster, and more reliably. Manufactured and filled in the USA using DOT-approved canisters, this green gas is designed for peak performance and consistent output across a wide range of conditions. Formulated with a silicone-based lubricant, Hostile Green Gas protects and conditions internal O-rings and seals, preventing dry rot, leaks, and long-term wear inside gas magazines, pistols, rifles, and gas-powered grenades. With an output of approximately 115 PSI at 70°F, this blend delivers stability and power shot after shot. Built with safety in mind, each can features an integrated pressure-release valve that automatically vents excess pressure caused by heat or over-pressurization, reducing explosion risk and ensuring true field-ready reliability.
