In the figure above you need to know 3 measurements.
- Sight Radius = Distance from rear sight to front sight in inches.
- Distance to Target = Distance from front of barrel to target in inches.
- Error = Amount of error in inches.
Adjustment in inches = ( Sight Radius * Error ) / Distance to Target.
For example if your revolver shoots 2.5" low at 25 yards (25*36= 900) and your sight radius in 5.00 inches then:
5.0" * 2.5" / 900" = 0.01388888" is the amount to adjust.
Depending on direction of error.
Front Sight Rear Sight
Error is LOW LOWER RAISE
Error is High RAISE LOWER
If you need to These sights are adjustable in the rear.
