How To Zero Fixed Revolver Sights

This guide details the process of adjusting fixed rear sights on a revolver by carefully milling the sight notch. The instructor demonstrates using a milling machine with an indicator to ensure precise, incremental adjustments. The process involves making light cuts, test firing, and repeating until the firearm is zeroed, emphasizing controlled material removal for accurate sight alignment.

Quick Summary

Adjusting fixed rear sights on a revolver is achieved by milling the sight notch. This process involves making precise, incremental cuts with a milling machine to shift the point of aim. For example, milling the left side of the notch allows for adjustment to compensate for shots impacting left, ensuring the firearm is accurately zeroed.

Frequently Asked Questions

How do you adjust fixed rear sights on a revolver?

Adjusting fixed rear sights on a revolver typically involves carefully milling the sight notch. By removing material from one side of the notch, you effectively shift the point of aim. For instance, milling the left side allows the front sight to be adjusted further right, compensating for shots that impact left.

What tools are needed to mill fixed revolver sights?

To mill fixed revolver sights, you will need a milling machine, an indicator to ensure the sight is level, and a milling cutter. Precision is key, so a stable setup and controlled movements are essential for successful adjustment.

How much material should be removed when milling a revolver sight?

It's best to remove material in small, incremental amounts, such as 0.005 inches, when milling a revolver sight. After each small adjustment, test fire the firearm to check the point of impact and continue making adjustments until the sights are properly zeroed.

Can milling fixed sights on a revolver alter the sight notch shape?

Yes, milling fixed sights can alter the shape of the notch. You might end up with a square bottom in a rounded area, depending on the original sight cut. This is generally acceptable and does not affect the functional ability to sight the firearm.
