If the shot is below the target and needs to be higher, it could be achieved using both sights facing towards the target, either the rear sight should be moved higher or the front sight should be lowered. Keep in mind: Adjust the rear sight in the same direction to get it in harmony with the point of impact to move & the front sight is adjusted on the contrary. If the shot is above the target and needs to be lowered, the way to go about it is using both sights pointing straight at the target, the rear sight should be moved downwards, or the front sight should be moved upwards. Afterward, they are adjusted to move the line of sight closer to the group, and the process is repeated until the perfect alignment. However, in the real world, it generally takes numerous attempts to establish a group. Theoretically, it is possible in a single shot-fasten the firearm into a vise, fire a shot, and adjust the sights, resultingly, they point at the center of the target.

Line of sight to meet the point of impact with precision. Even, if you have got the best iron sights but if the sights are not adjusted the way they should be, they won’t hit the target.
