What must be done when clearing the M240 after raising the feed tray?

When clearing the M240 after raising the feed tray, it is crucial to visually and physically inspect the chamber for ammunition. This step is essential to ensure that no rounds remain in the chamber, which could lead to an accidental discharge or other safety hazards. By taking the time to conduct both a visual and a tactile inspection, the operator confirms that the weapon is clear and safe to handle, preventing unintended consequences. This procedure aligns with best practices for weapon handling and safety protocols, underscoring its importance in firearm operation and maintenance.

Reviewing the operating manual, extracting the belt ammunition, and replacing the feed tray cover are important actions related to the operation of the M240, but they do not specifically address the immediate safety concern of confirming that the chamber is clear. Therefore, the inspection of the chamber takes priority when the feed tray is raised.
