What action should be taken first when performing a malfunction clearance on the M249 AR?

When performing a malfunction clearance on the M249 Automatic Rifle (AR), the first action that should be taken is to clear the weapon. This step is crucial for ensuring safety and preventing any accidental discharges. Clearing the weapon involves placing it in a safe condition by removing the ammunition source and ensuring the chamber is empty.

Once the weapon is cleared, you can safely proceed to inspect other elements, such as the ammunition and the chamber, to diagnose the malfunction without the risk of the weapon firing. By prioritizing the weapon's safety first, you establish a secure environment for further troubleshooting and maintenance. This systematic approach minimizes the risk of injury to personnel and maximizes the effectiveness of the malfunction clearance process.
