Gas-operated systems are mechanisms that utilize gas pressure to perform work. Commonly found in firearms, these systems use the gas produced from igniting gunpowder to cycle the action, eject spent cartridges, and load new rounds. This method enhances the efficiency and reliability of the firearm. In addition to firearms, gas-operated systems are also used in various machinery and engines, such as internal combustion engines. These systems harness the energy from gas to power pistons or turbines, converting chemical energy into mechanical energy, which is essential for many modern vehicles and industrial applications.
