What is the sustained rate of fire for the M4A1 service rifle?

The sustained rate of fire for the M4A1 service rifle is characterized by a consistent firing tempo that allows for effective use over an extended period without overheating the weapon. This rate typically ranges from 12 to 15 rounds per minute. The rationale behind this specific range involves maintaining accuracy and barrel cooling, as a higher rate of fire could lead to overheating and degradation of the weapon's performance. In practical terms, this means a soldier can fire between 12 to 15 rounds consistently while still allowing for necessary pauses to ensure accuracy and the longevity of the rifle during operations. This sustained rate of fire reflects a balance between operational effectiveness and maintaining the reliability of the firearm in various combat scenarios.
