There are several different designs. Spring: when you cock the rifle is compresses a spring in an air tube. When you fire, it releases the spring and the spring forced air out of the tube and this fires the BB out of the barrel. C02; A C02 cylinder holds gas and each time you pull the rigger some gas is released into the chamber behind the BB and this gas fires a BB out of the barrel. Air: You have to pump the gun or rifle with an onboard pump several times to store compressed air in a chamber. When you pull the trigger it releases the air and this fires the BB out of the barrel.
Rooms with a gas fire place need fresh air because the gas and the fire put off too much carbon monoxide. The fresh air will keep you from getting carbon monoxide poisoning.
