What does sight alignment refer to?

Sight alignment refers specifically to lining up the rear and front sights of a firearm to ensure accuracy when aiming at a target. Proper sight alignment is crucial for hitting the intended mark because it ensures that the shooter’s line of sight is in direct alignment with the barrel of the firearm. The rear sight is adjusted to allow for a clear view of the front sight, which must be centered within it and aligned with the target. This alignment is fundamental in marksmanship, as any misalignment can lead to inaccurate shots.

The other options pertain to different aspects of shooting but do not represent the concept of sight alignment. Aiming without assistance refers to shooting skills and practices without external help, adjusting scope settings involves fine-tuning the optics to improve long-range accuracy, and establishing distance to the target concerns estimating how far away the target is for better shot placement. These factors are important in their own right, but they do not define sight alignment.
