What is the maximum effective range of the M16?

The M16 rifle has a maximum effective range that is officially recognized as 550 meters when using standard 5.56mm ammunition. This range is established based on the ability of the rifle to deliver accurate fire with sufficient lethality to target engagements within that distance. The effective range is influenced by several factors, including the proficiency of the shooter, environmental conditions, and the type of ammunition being used. While the rifle can technically deliver rounds beyond this distance, it is within the 550 meters range that the M16 is expected to perform most reliably, allowing for both accuracy and efficient target engagement. Understanding this range is crucial for tactical planning and operational effectiveness in the field.
