Pyramid Sight System Elevation Modification Instructions:

The amount of needed shim will vary depending on the firearm, caliber, load, and particular barrel and/or rail.  Start with one .015″ (pink) shim then add additional shims as necessary. Each increment of .002″ to .0025” of elevation shim will affect bullet impact by approximately 1″ at 25 yards.
