Gas Powered Airsoft Guns
Gas Powered Airsoft Guns Gas-powered airsoft guns use
pressurized gas to propel pellets. These guns are capable of automatic and
semi-automatic operation. The most common gases used are "green gas" (which
consists of a mixture of propane and a polysiloxane lubricant)
and HFC-134a. Less commonly used gases include "red gas" (which is
actually HCFC-22), CO2 and nitrogen/high
pressure air. Red gas is usually avoided unless the airsoft gun has
undergone modification, as its relatively high critical pressure can cause
damage to the airsoft gun. CO2, nitrogen, and high
pressure air are less common because they need to be stored at higher
pressures than "green gas" or HFC-134a.
