Gas operated systems are mechanisms that utilize gas pressure to perform work. Commonly found in firearms, these systems use the gas produced from burning gunpowder to cycle the action of the firearm, eject spent cartridges, and load new rounds. This method enhances the efficiency and reliability of the weapon. In addition to firearms, gas operated systems are also used in various machinery and engines. For example, in automobiles, gas-operated engines convert fuel into energy, using the pressure generated to move pistons. This principle is fundamental in many modern technologies, providing power and functionality across different applications.
