Which statement best describes when to perform a function check?

• A. It should be performed constantly during use.
• B. It should be avoided to prevent wear.
• C. It should be conducted after maintenance or installing a new component.
• D. It is unnecessary if the weapon is clean.

Answer: (C)

A function check is performed after maintenance or after installing a new component to verify that the firearm operates correctly with the recent changes. This step confirms that the action cycles, the safety functions as intended, and the trigger and reset work properly, ensuring the weapon will function safely before returning to service. It’s not meant to be done constantly during use, and simply being clean doesn’t guarantee reliability. After maintenance or part installation is the proper time to confirm everything works together as designed.
