What is the transition time between bursts at the sustained rate of fire for the M240B?

The transition time between bursts at the sustained rate of fire for the M240B is 4-5 seconds. This time frame is essential for maintaining optimal functioning of the weapon system while preventing overheating. Sustained fire is characterized by firing at a rate that allows for cooling between bursts, which helps to maintain accuracy and prolong the life of the barrel.

The 4-5 second interval is designed to provide sufficient cooling for the barrel after a burst of fire, ensuring that the weapon does not become too hot to operate effectively or safely. This cooling period allows the barrel temperature to decrease, which minimizes the risk of malfunctions or damage to the weapon due to excessive heat buildup. Understanding this timing is crucial for gunners to apply proper firing techniques in different combat scenarios, ensuring effectiveness while also preserving the integrity of the machine gun.
