What should be done if you encounter excessive resistance while operating the M240?

When encountering excessive resistance while operating the M240, the best course of action is to inspect for obstructions. Excessive resistance is typically a sign that something is wrong, such as a blockage or foreign material interfering with the weapon's mechanisms. Conducting a thorough inspection allows the operator to identify any obstructions that may be causing the issue, ensuring that the weapon functions properly and safely.

This step is critical, as forcing the weapon to operate or applying lubricant without first diagnosing the problem can lead to more significant mechanical issues or malfunctions. Contacting maintenance personnel is also important, but it should be a follow-up action taken after identifying the nature of the resistance in order to provide them with accurate information.
