Which of the following describes proper sight alignment?

Proper sight alignment is fundamental to accurate shooting. The correct choice emphasizes that the front sight must be centered within the rear sight's aperture or notch. This alignment ensures that the shooter can maintain a consistent point of aim, which is critical for precision when taking a shot. When the front sight is properly aligned with the rear sight, the shooter can effectively focus on the target while keeping the sights aligned, leading to better accuracy.

In contrast, other options suggest incorrect practices. Misaligning the sights for a wider field of view can result in decreased accuracy, as the shooter may not be able to intuitively gauge where the bullet will strike. Similarly, having the rear sight higher than the front sight disrupts the alignment necessary for straight shooting. Lastly, adjusting the sight based on distance is important for calibration, but it does not pertain to sight alignment itself; sight alignment should always prioritize centering the front sight with the rear sight for any distance.
