M240B is fired from what position?

• A. Closed bolt position
• B. Semi-automatic position
• C. Open bolt position
• D. Fully automatic position

Answer: (C)

Open-bolt operation is used to manage heat during sustained automatic fire. In the M240B, the bolt is held to the rear when the gun is ready, with the chamber empty. When you squeeze the trigger, the bolt moves forward, chambers a round, and fires, then continues cycling as long as the trigger is held and ammunition is available. This open-bolt state helps keep the breech cooler and reduces the risk of cook-off during rapid, continuous fire. The other options describe firing modes or bolt states that aren’t how the M240B is configured for automatic fire.
