What is the maximum range of the M4 carbine?

The maximum effective range of the M4 carbine is indeed 600 meters. This range represents the distance at which the weapon can be expected to consistently hit a target in combat conditions. The M4 is designed for versatility in various combat situations, providing accuracy and stopping power within this range. Its lightweight design, shorter barrel, and adjustable sighting systems contribute to its performance, making it a highly effective weapon for both close quarters and longer-range engagements.

When considering the other options, it's important to note that while the M4 can technically fire a round beyond 600 meters, effective targeting and engagement become significantly less reliable at those distances. The weapon's design and the ballistics of the round it fires determine the optimal range for achieving effective accuracy, which is why 600 meters is recognized as the maximum effective range for the M4 carbine. A target beyond this distance would likely exceed the capability of effective fire, thus being less practical in operational environments.
