What is the sustained rate of fire for the M16A2 rifle?

The sustained rate of fire for the M16A2 rifle is recognized as being between 15-25 rounds per minute (RPM). This rate is defined as the amount of ammunition that the rifle can consistently fire while maintaining accuracy and preventing overheating. It is crucial for operational effectiveness, particularly in defensive and suppressive fire situations. The sustained rate of fire takes into account the need for the shooter to maintain control over the weapon, allow for periods of cooling, and perform necessary tactical maneuvers. Understanding the sustained rate helps in planning ammunition logistics and establishing effective firing strategies during engagements.
