Which part of the M240 should be inspected after the ammunition belts have been removed?

The correct answer focuses on the importance of inspecting the chamber for rounds and brass after removing the ammunition belts. This step is crucial because it helps ensure that the weapon is clear and safe for handling. A thorough inspection of the chamber checks for any live rounds or spent cartridge casings that may still be lodged within, which could pose a safety risk during maintenance or operation.

Additionally, looking into the chamber after removing ammunition belts allows for the identification of any potential malfunctions or blockages that could affect the weapon's performance. Ensuring that the chamber is clear contributes to a thorough safety protocol in handling the M240.
