As CO2 is almost always a gas at the the temperatures normally found on Earth, it is pressurized and mixed with oil so that it becomes a liquid for storage in containers suitable for use in air guns.

Some air guns use spring-powered pistons to compress regular air as a source of propellant. The cra
