Calculating Rear & Front Sight Height Combination:

1. Measure the diameter of the barrel at the point of the rear sight is going to be installed and at the point of the front sight going to be installed (example: 1.0" rear sight and .750" front sight).
2. Divide the diameters by 2 (example: 1.0" / 2 = .500" and .750" / 2 = .375").
3. Check the rear sight height adjustment chart. You want to be about 1/3 up from bottom adjustment. using a sporting rear #67 adjusts from .300" to .510". Total adjustments is .210". Divide .210" / 3 = .070". Add the .070" to the lowest adjustment height (which is .300") and you come up with .370". This is 1/3 up from bottom adjustment.
4. Add the 1/3 adjustment to the center line distance (example: .370" + .500" = .870").
5. Subtract the front sight center line figure from the rear sight height (example: .370" + .500" = .870").
6. You need a combination of front ramp and front sight with the height of .495". Ramps are measured from the base to the bottom of the dovetails. Front sights are measured from the bottom of the dovetail to the top of the bead.
7. Or you could go with a front sight height of .588". .495" (height need from top of barrel to top of sight) + .093" (which is the depth of the dovetail cut in barrel).
