What is the sustained rate of fire for the M249?

The sustained rate of fire for the M249 is 85 rounds per minute. This rate of fire is vital for maintaining effectiveness during prolonged engagements while managing heat buildup and ammunition consumption. The sustained rate allows gunners to employ the weapon effectively without overheating it, which is crucial for ensuring reliability and accuracy in various combat scenarios.

The M249 is designed to provide a balance between firepower and controllability, making this rate of fire an optimal choice for infantry maneuvers. A higher rate of fire can lead to excessive heat, potentially causing malfunctions and reduced accuracy, while a lower rate may not offer sufficient fire support. Thus, understanding and adhering to the established sustained rate of fire is essential for effective gunnery practice in the USMC.
