YOU can calculate the exact front sight height needed.
Shoot it @ 100yds with the issue front sight, and the Skinner set in the middle of it's elevation adjustments.
Measure, in inches, how high/low (probably high) your POI is above your POA @ 100yds.
Plug that measurement into one of the online sight height calculators at the Skinner or Brownell's websites to find out what your front sight height should be.
