What is the effective range for a point target using the M4?

The effective range for a point target using the M4 is indeed 500 meters. This distance is determined based on the rifle's design and ballistics characteristics, specifically concerning accuracy and lethality. The M4 carbine is optimized for engagement at moderate ranges, which makes 500 meters a practical and realistic range for accurate engagement of point targets, assuming the shooter is trained and conditions are conducive to effective shooting.

While other options suggest longer ranges, they exceed the effective combat engagement distances typically associated with the M4. Beyond 500 meters, factors such as environmental conditions, bullet drop, and target movement can significantly impact hit probability, making it increasingly challenging to engage point targets reliably. Thus, the 500-meter range is recognized as the effective maximum for skilled personnel to maintain accuracy with the M4.
