Sight Height


How do you determine the sight height of your scope/sights on your rifle or handgun?

You measure, using a ruler, from the approximate center line of the scope (where the horizontal crosshair is in the scope) to the center line of the barrel.

For scoped rifles, this is typically 1.5 inches, but it can vary, depending on scope height.
For handguns or rifles using open/iron sights, it is around 0.9 inches (measure to the top of the front sight).

What if you mounted a laser under the barrel of your rifle or handgun? You would measure from the center line of the barrel to the center line of the laser. Enter the sight height as -1.5 or whatever the value is (make sure you include the negative sign).
