What should you check first if your M240 experiences a misfire?

The first step when experiencing a misfire with the M240 is to look for issues with the ammunition. Misfires can often be attributed to faulty or improperly loaded ammunition, which includes problems such as ammunition that is damaged, has incorrect or improperly seated primer charges, or is not compatible with the weapon system. Ensuring that the ammunition is in good condition is paramount, as even a perfectly functioning weapon cannot fire if the ammunition is compromised.

Addressing ammunition issues first allows the operator to rule out one of the most common causes of misfires, ensuring that any further steps taken—like inspecting the weapon itself—are necessary. Identifying ammunition issues also prevents wasting time and effort on mechanical checks if the root cause lies within the ammunition itself. Furthermore, a thorough understanding of your ammunition type and its condition is vital in maintaining overall weapon reliability and readiness.
