In this blog post, we will explore an easy trick to get your rifle’s bore sight perfectly zeroed using a lathe. Whether you are a seasoned shooter or just starting, this method is a great way to ensure your rifle’s accuracy and achieve outstanding shooting results. So, let’s dive in and discover how to zero a bore sight for your rifle using a lathe.

Are you struggling with zeroing your scope or firearm sights? Are you looking for an easy solution to help you with bore sighting? There is a tool called a bore sight that can be used to adjust your scope, helping you to hit your target with pinpoint accuracy. However, if the bore sighter is improperly aligned, it can leave you frustrated and shooting way off target. In this article, we will explore an easy trick to zero a bore sight for your rifle with a lathe.

How does a bore sight work?
Before diving into the process of zeroing your bore sight with a lathe, let’s understand how a bore sight works. A bore sight emits a laser beam that is aligned with the axis of the bore. The laser is projected through the bore of the firearm and into the distance, allowing you to adjust the scope or sights until the laser is directly on target. This process gets you significantly closer to your optimal zero position, narrowing your groupings before you even take your first test shots.

Using a Bore Sight to Zero Your Rifle
Now that you understand the benefits of using a bore sight let’s look at how to zero your rifle using a bore sight and a lathe.

Step 1: Align the bore sighter
The laser diode of a bore sighter may not be perfectly centered, making sighting the distance difficult. To solve this problem, first, check to see if the bore sighter is properly aligned. If not, you can do this by adjusting screws on the device. There are four screws in most bore sighters that can be adjusted with the use of an allen key. Loosen the screws slightly if the beam is too high or too low and tighten them if the beam is off-center.

Step 2: Rotate the Bore Sighter
Place the bore sighter on your lathe with the beam directed away from any objects that can cause reflection or deflection. Turn on the lathe slowly and observe the laser beam. You should see the beam straight and steady. If not, the bore sighter is not aligned.

Step 3: Adjust the Screws
If the beam is off-center, adjust the screws on the bore sighter. Loosen the two screws that are opposite each other, and tighten the other two screws in the opposite direction to get the beam centered. Repeat the process until the beam is perfectly centered.

Step 4: Repeat the Process
Use the lathe to rotate the bore sighter and make sure the beam does not move. A rifle vise can also be used to stabilize the bore sighter. As with any adjustment, firing a few rounds is necessary for perfect alignment.

Zeroing a bore sighter for a rifle with a lathe is an easy and efficient way to improve accuracy. It requires finesse and precision, but anyone can do it with consistent practice. This method ensures that you’ll be shooting accurately and confidently on your first rounds at the range.
