- Align the sights: Look through the rear sight aperture and line it up with the front sight post. Your goal is to center the target using the front post while looking through the rear aperture.
- Adjust if needed: Use the adjustment knobs or screws to move the sights horizontally or vertically. This allows you to zero your rifle and improve accuracy.
- Aim and shoot: With the sights aligned on your target, you can confidently pull the trigger knowing your aim is guided by the build sights.
By following these basic steps, builder sights help create a reliable aiming system without complex optics. They are simple, durable, and easy to use, especially as a backup in case main optics fail.
