What should be done if the M240 experiences a “failure to fire”?

In the case of a “failure to fire” with the M240, it is important to allow time before inspecting the firing mechanism. This pause is crucial because a failure to fire may be due to a hangfire, where the round is still in the chamber but has not ignited, posing a significant safety risk if the weapon is immediately cleared. Typically, a designated wait time (often around 30 seconds) is recommended to ensure that any delayed ignition can occur.

After this waiting period, the operator can safely inspect the firing mechanism and determine the cause of the failure. This methodical approach prioritizes safety and ensures proper handling of potentially dangerous situations during weapon operation. Being vigilant and following established protocols reduces the risk of accidental discharges, enhancing the overall safety of the crew and the effectiveness of the mission.
