Enter the line of sight and the optic center to rifle bore distance into the calculator to determine the sight height. This calculator helps in setting up a firearm scope for accurate shooting.
Sight Height Formula
The following formula is used to calculate the sight height:
SH = LOS - OC
Variables:
- SH is the sight height (inches)
- LOS is the line of sight from the shooter’s eye to the target (inches)
- OC is the distance from the optic center to the rifle bore (inches)
To calculate the sight height, subtract the optic center to rifle bore distance from the line of sight distance.
What is Sight Height?
Sight height is the vertical distance between the center of the bore of a firearm and the optical axis of the sighting device, such as a scope. This measurement is crucial for accurate shooting as it affects the bullet’s point of impact, especially at different ranges. Properly calculating and adjusting the sight height can improve the accuracy of long-range shots.
How to Calculate Sight Height?
The following steps outline how to calculate the Sight Height.
- First, measure the line of sight (LOS) from the shooter’s eye to the target in inches.
- Next, measure the distance from the optic center to the rifle bore (OC) in inches.
- Use the formula SH = LOS – OC to calculate the sight height (SH).
- Finally, enter the measurements into the calculator to get the sight height in inches.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem:
Use the following variables as an example problem to test your knowledge.
Line of sight (LOS) = 2.5 inches
Optic center to rifle bore (OC) = 1.5 inches
