When a stoppage occurs, what should be your immediate action after shouting "misfire" three times?

After shouting "misfire" three times, the immediate action to take is to try and move the bolt to the rear of the gun. This step is crucial because it allows the operator to clear any potential obstruction or issue that may be causing the stoppage. Moving the bolt to the rear can help ensure that the firearm is safe and functioning correctly.

This action helps in revealing whether a round is still chambered or if there's a failure to extract the spent casing. It is a necessary safety measure to address the stoppage and progress toward clearing the malfunction. Being proactive in this manner is essential in maintaining situational awareness and ensuring the safety of the crew and the surrounding environment.

The other choices do not prioritize safety or effective resolution of the issue. Waiting indefinitely for assistance could lead to unsafe conditions, while performing a safety check without addressing the immediate mechanical issue may prolong the situation unnecessarily. Attempting to fire another round is typically not advisable in case of a confirmed misfire, as it poses a severe risk of an unexpected discharge or further complications in the firearm's operation.
