Short: height adjusts from .50″ to .75″ above bore height, suitable for front sights up to .375″ on Favorite rifles with muzzle diameter about .65″

To be sure you are getting the correct rear sight, use the following formula to find the height of your front sight above the bore:
(muzzle diameter / 2) – .080″ + front sight height
If you are shooting at longer distances, you may need extra height in your rear sight to compensate for the bullet’s drop
