What is the maximum range of the M27 Infantry Automatic Rifle (IAR)?

The maximum range of the M27 Infantry Automatic Rifle (IAR) is indeed 800 meters for effective fire. This range is defined by the rifle's capabilities in delivering accurate fire at distance, which is crucial for infantry engagements.

The M27, designed primarily for suppression and close support in combat situations, benefits from its design features that enable it to effectively deliver rounds at this maximum range while maintaining a manageable rate of fire. This capability allows infantry units to increase their firepower in engagements, providing a distinct advantage in both offense and defense.

The other mentioned ranges do not accurately reflect the effective maximum range of the M27, as they are lower than the actual capability of the rifle. The correct understanding of the weapon's performance is essential for effective tactical planning and operational effectiveness in field conditions.
