Calculating Sight Correction
In order to get the most out of your new firearm, or maintain one you already own, usually requires you to sight it in. Whether using iron sights, scopes or red dots, the calculations provided by this tool will help you get the job done and make the most of your time shooting.
Use this calculator to determine how much you need to move your sights to correct your point of impact. All units entered must be in decimal format for this calculator to function.
Rear Sight Corrections
Rear sight corrections move in the direction that you wish to move the bullets impact. So if you are shooting low and can move your rear sight you would move it UP by the amount indicated.
Front Sight Corrections
Front sight corrections move in the opposite of the direction that you wish to move the bullets impact. So if you are shooting low and can move your front sight you would move it DOWN by the amount indicated.
Please remember that if your shots need to move diagonally to hit the center of the target you will need to perform this calculation TWICE. Once for the horizontal movement required and once for the vertical movement required.
