What is the maximum effective range for grazing fire with the M240-B?

The maximum effective range for grazing fire with the M240-B is 600 meters. Grazing fire is a technique used to engage targets while keeping the projectiles flying just above the ground, making it effective against enemy personnel in the open or near cover. At 600 meters, the M240-B is capable of maintaining a flat trajectory, allowing for precise targeting and minimizing the risk of rounds ricocheting off the ground.

Other ranges listed, such as 800 meters, 3725 meters, or 1800 meters, refer to different application scenarios for the weapon. For instance, 800 meters is often considered the maximum effective range for most direct fire engagements, while the much larger figures pertain to the weapon's overall range capabilities, which are not applicable for grazing fire. Thus, knowing the correct parameters for different firing techniques, like grazing fire, is crucial for effective combat operations.
