The guide advises prioritizing rear sight adjustments for simplicity and accuracy.

Quick Summary

When adjusting iron sights, remember that to raise the Point of Impact (POI), you raise the rear sight. However, to achieve the same POI increase with a front sight, you must lower the front sight. Front sight adjustments are opposite to rear sight adjustments.

Frequently Asked Questions

How do you measure a handgun front sight for replacement?

To measure a handgun front sight for replacement, you measure its height from the very top of the sight blade down to the top surface of the firearm's slide. This ensures you select a sight with the correct height for proper zero.

What is the correct way to measure a rifle front sight?

For rifle front sights, the measurement is taken from the top of the sight blade down to the bottom edge of the dovetail cut. This method is distinct from handgun front sight measurements and is crucial for accurate replacement.

How do front and rear sight adjustments affect Point of Impact (POI)?

To raise your Point of Impact (POI), you raise the rear sight. Conversely, to raise POI with a front sight, you must lower the front sight. Front sight adjustments are opposite to rear sight adjustments for both elevation and windage.

What is the best practice for adjusting iron sights?

The recommended practice for adjusting iron sights is to always try to adjust the rear sight for both elevation and windage. This simplifies the process and reduces confusion compared to adjusting the front sight.
