If a shot is left, which direction should the rear sight be adjusted?

When a shot consistently lands to the left of the intended target, adjusting the rear sight to the right is necessary to correct the aim. This adjustment works by changing the line of sight of the rifle or pistol, effectively moving the point of impact to the right, aligning it more closely with where the shooter is aiming.

In practice, when the rear sight is moved to the right, the shooter is creating a slight angle to the left in relation to the bore of the firearm, enabling bullets to strike closer to the center of the target. This is based on the principle that for every adjustment made to the rear sight, the point of impact shifts in the opposite direction of the adjustment. Thus, moving the rear sight right compensates for the shots hitting left of the target.
