Gas Airsoft
Guns are powered by compressed refrigerant gas, The compressed gas is inserted
in a valve that is usually on the bottom of a removable magazine. The gas
is then stored in a well in the middle section of the magazine and then
released through another valve when the trigger is pulled. When the trigger
is pulled, a pin pushes the release valve causing the gas stored in the
gas well in the magazine to exit the pistol through the magazine past the
barrel section while propelling the BB.
