During remedial action on an M4, which step is performed first?

• A. Check the chamber
• B. Remove the magazine
• C. Place the weapon on safe
• D. Lock the bolt to the rear

Answer: (C)

Placing the weapon on safe is the first move because safety comes before any handling during remedial action. By engaging the safety, you prevent the trigger from being moved accidentally as you inspect and clear the rifle, reducing the risk of an unintended discharge while you diagnose the malfunction. After that, you would follow the remaining clearing steps—removing the magazine, locking the bolt to the rear to inspect the chamber, and so on—to identify and clear any obstruction or misfeed. The other actions are essential parts of clearing, but they should come after you establish safety first.
