What is the sustained rate of fire for the M240B machine gun?

The sustained rate of fire for the M240B machine gun is 100 rounds per minute. This rate allows for consistent and effective engagement of targets while managing the heat buildup in the weapon. Sustained fire is designed to minimize overheating and barrel wear, making it crucial for maintaining the weapon's functionality during extended engagements.

The M240B is designed for continuous firing, but to ensure reliability and performance, its sustained rate reflects the appropriate rhythm for firing while allowing for adequate cooling intervals. This is in contrast to other rates of fire such as cyclic or rapid fire, which are higher but not sustainable over the long term due to heat generation. In a practical combat scenario, understanding and employing the sustained rate enables operators to maximize effectiveness while preserving the operational integrity of the weapon system.
