Achieving precision in shooting requires not only skill but also the right tools and techniques. Bore sighting is one such technique that proves invaluable for marksmen. But what exactly is bore sighting, and how can you master it? Let’s explore.

Bore Sighting: A Step-by-Step Tutorial

Bore sighting might seem like a task for seasoned marksmen, but with proper guidance, anyone can learn it. Here’s a comprehensive step-by-step guide:

Step 1: Prioritize Safety – Verify the Firearm is Unloaded

Before starting a bore sighting, ensure safety by double-checking that the firearm is unloaded. Remove the magazine, then open the action to visually inspect the chamber. A few seconds of vigilance can help to avoid major mishaps.

Step 2: Stabilize Your Firearm – Ensure Stability

To get an accurate bore sight, the rifle must be held steady. Using a gun vise is ideal, but sandbags or other rests can also work. The objective is to keep the firearm stationary throughout the process.

Step 3: Insert the Bore Sight – Select the Appropriate Type

Muzzle-inserted and chamber-inserted bore sights are the two primary varieties. When employing muzzle-inserted bore sights, slide them carefully into the barrel’s end. For those that are chamber inserted, place it within the chamber just like a cartridge. A laser or a visual reference point for alignment will be produced using the best laser bore sight.

Step 4: Align Your Sights – The Core of the Process

To observe the reference point that the laser bore sight provides, such as a laser dot or another marker, look through the sights or scope of your rifle.  Adjust the crosshairs or sights to align with this reference. This step ensures that your sights or scope are properly aligned with the bore’s true center.

Step 5: Fine-Tune the Alignment – Attention to Detail

After you have overall alignment, fine-tune it by slightly adjusting your sights or scope until they are precisely centered on the reference of the bore sight. Patience is crucial, as small adjustments can greatly enhance accuracy.

Using a Red Dot Sight with a Bore Sight

You can zero a red dot sight using a bore sight. The process is similar to that for other optics. Typically, 25 yards is a recommended starting distance for initial bore sighting.

The Advantages of Bore Sighting


Every round counts in shooting, both in terms of cost and firearm wear. Bore sighting significantly reduces the number of rounds needed to zero your sights or scope, saving ammunition, and time, and reducing wear on your firearm.


Bore sighting provides a solid foundation, ensuring that every subsequent adjustment to your sights or scope is more accurate. 


Bore sighting allows you to align your firearm’s sights without firing a shot. Bore sighting is a silent solution that works well if you want to avoid disturbing the peace or are in an area where shooting is not an option.

What is the Ideal Distance for Bore Sighting?

While 25 yards is a common distance, factors such as firearm type and intended use can influence the ideal range.

How Much Does Bore Sighting Cost?

DIY methods can be almost free, while professional services might charge between $20 and $50. The price range for laser bore sights varies based on brand and quality, from $30 to over $100.

Expert Tips for Successful Bore Sighting

  • Optimal Distance: For many rifles, starting at 100 yards is effective, though this may vary based on the rifle and ammunition.
  • Regular Checks: Periodically verify your zero, especially if the firearm has experienced any impacts.
  • Traditional Methods: If you don’t have a laser, traditional bore sighting by looking through the bore to align with a distant object is still effective.
