What is the maximum effective range of the M16A2 on a point target?

The maximum effective range of the M16A2 on a point target is 550 meters. This figure represents the distance at which a trained marksman can effectively engage a target with accurate and controlled fire using the weapon. The M16A2's design allows for precision aiming and high velocity, contributing to its effectiveness at this range. The rifle's capability to maintain accuracy at distances up to 550 meters is fundamental for military operations, as it enables personnel to engage various threats while remaining at a safe distance.

The other choices, while they may reflect capabilities of the M16A2 in different contexts such as area targets or under varying conditions, do not align with the specific effective range for point target engagement, which is firmly established at 550 meters. This knowledge is critical for operations planning and tactical engagements in combat situations.
