In firearms terminology, which term refers to a fully automatic weapon operated by the energy of the gas?

• A. Bolt-action
• B. Gas operated
• C. Spring powered
• D. Pneumatic

Answer: (B)

The term that correctly describes a fully automatic weapon operated by the energy of the gas is "gas operated." This classification indicates that the firearm utilizes the gases generated from the combustion of gunpowder in the cartridge to cycle the action. In gas-operated firearms, a portion of the gas is diverted through a port in the barrel to push a piston or operate a bolt carrier, thereby ejecting the spent cartridge and chambering a new round without the need for manual action by the shooter. This mechanism is fundamental to the operation of many modern automatic and semi-automatic weapons, as it allows for rapid fire and efficient cycling of rounds. This operating system is distinct from the other choices, which represent different methods of firing mechanisms in firearms. Bolt-action relies on manual cycling of the action, spring powered refers to mechanisms using a compressible spring for operation (commonly seen in airsoft and BB guns), and pneumatic relies on air pressure for propulsion instead of gas from combustion.
