How often should the M240 be cleaned and maintained?

The correct approach to cleaning and maintaining the M240 is to do so after each use or when the weapon is dirty. This frequency ensures that the firearm operates reliably and safely. Regular maintenance is crucial because the operational environment can introduce dirt, dust, and debris that may affect the weapon's performance. Additionally, cleaning the M240 after each use helps to prevent carbon buildup, which can lead to malfunctions if not addressed promptly. This practice is in line with military standards and best practices for weapon care, emphasizing that a weapon should always be maintained in optimal condition to ensure its readiness for use at all times.
