What is the effect of raising the rear sight on bullet impact?

When the rear sight is raised, it causes the angle of the barrel to change, effectively increasing the line of sight above the line of the bore. As a result, the bullet will rise higher in its trajectory before eventually falling due to gravity. Therefore, raising the rear sight will cause the bullet to impact lower than where the sight is aimed at a specific distance. Understanding this relationship is crucial for making precise adjustments in shooting to ensure that the point of aim aligns with the point of impact.

In this context, when a shooter wants to adjust for a perceived higher trajectory of the bullet, lowering the rear sight will create a point of aim that corresponds to the bullet's impact zone. This highlights the importance of sight adjustments in relation to bullet drop and the trajectory caused by gravity.
