What is the sustained rate of fire for the M4 Rifle?

The sustained rate of fire for the M4 Rifle is 12-15 rounds per minute. This rate is considered the sustained firing capacity that can be maintained over a longer period without risking overheating the barrel or causing malfunctions due to excessive firing.

Sustained rate of fire is typically defined in the context of maintaining accuracy and control while achieving effective firepower. In contrast to higher cyclic rates of fire, the sustained rate helps ensure that the ammunition can be used effectively for operational purposes without compromising the weapon's integrity or reliability. This rate takes into account the need for barrel cooling and the necessity for the shooter to reset and engage targets properly.
