What does the term "bore sighting" refer to with the M240?

Bore sighting refers to the process of aligning the weapon's sights with the barrel to ensure that the point of aim corresponds with the point of impact on a target. This is particularly important for the M240 machine gun, as it allows the shooter to achieve greater accuracy by ensuring that any adjustments made to the sights are reflective of the actual trajectory of the rounds being fired. By aligning the sights directly with the bore of the barrel, users can correct any misalignments and improve overall targeting effectiveness. This process is a fundamental aspect of maintaining and operating the firearm accurately, ensuring that when the trigger is pulled, the rounds will hit where intended.
