Sight Height Calculators
The goal is to make the front and rear sights the same height above the center of the barrel. When you make your measurements you MUST use a caliper or micrometerto come up with a decimal number (for example, .875) in inches for the calculator to work. A few thousandths can have a substantial effect on your sights performance.
Front Sight Height
