How many rounds can the M240B fire in one minute with a hot barrel?

The M240B machine gun is capable of firing a high volume of rounds, especially when the barrel is hot, indicating that it has been previously fired and is thus more responsive. When operating at high rates of fire, specifically with a hot barrel, the M240B can achieve a cyclic rate of approximately 200 rounds per minute. This cyclic rate is indicative of the weapon’s design, which allows for sustained fire without significant overheating issues, especially when used within the specified operational parameters. Understanding the weapon's maximum rate of fire is crucial for effective target engagement and managing ammunition during combat scenarios, making the knowledge of this figure essential for any Marine trained in the use of the M240B.
