Which of the following describes the kind of weapon that fires from the open bolt position?

• A. Revolver
• B. Automatic rifle
• C. Shotgun
• D. Machine gun

Answer: (D)

The correct answer is a machine gun, as machine guns are designed to fire from the open bolt position. This design allows for cooling of the chamber and ensures that the weapon has a round ready to fire when the trigger is pulled. When the trigger is activated, the bolt closes, chambering a round, and then firing it. Firing from an open bolt configuration provides several advantages. It reduces the risk of an accidental discharge when loading the weapon, as the bolt remains back and is not in a position to strike a round. Additionally, this mechanism can improve cooling rates, which is particularly beneficial in sustained-fire scenarios typical of machine gun use. In contrast, revolvers, automatic rifles, and shotguns typically fire from the closed bolt position, where the chamber is sealed and a round is in place when the weapon is ready to fire. Understanding these differences is crucial for recognizing how various firearms operate under different conditions.
