What is the sustained rate of fire for the M240?

The sustained rate of fire for the M240 is defined as the rate that can be maintained over extended periods without overheating the weapon. The choice indicating 100 rounds per minute (RPM) in 6-9 round bursts aligns with the operational guidelines for sustaining effective and reliable firing capabilities.

The rationale behind this rate is that it allows the operator to maintain accuracy and control while managing barrel heat and ammunition expenditure effectively. Firing in 6-9 round bursts helps prevent overheating compared to a higher sustained rate, which would lead to expedited wear on the barrel and potential malfunctions.

Engaging targets at this sustained rate allows crews to provide continuous fire support while ensuring the weapon remains operational over time, particularly in combat situations where precision and reliability are paramount. Each burst's brevity helps with aiming and dispersing fire, reinforcing the effectiveness of the M240 in sustained engagements.
