Precision in shooting isn't just about skill; it's also about the tools and techniques at your disposal. One such technique that has proven invaluable for marksmen is boresight. But what is it, and how do you use it? Let's dive in.

How to use a boresight? - Step-by-Step Guide

Using a bore sight might seem like a task reserved for seasoned marksmen, but with a bit of guidance, it's a skill anyone can master. Here's a detailed breakdown:

Step 1: Safety First - Ensure the Firearm is Unloaded

Before you even think about bore sighting, safety should be your top priority. Always double-check to ensure the firearm is unloaded. Remove the magazine, open the action, and visually inspect the chamber. Remember, a few seconds of caution can prevent a lifetime of regret.

Step 2: Secure Your Firearm - Stability is Key

To get an accurate bore sight, your firearm needs to be as steady as possible. Using a gun vise is ideal, but if you don't have one, improvise with sandbags or rests. The goal is to ensure the firearm remains stationary throughout the process.

Step 3: Inserting the BoreSight - Choose Your Type

There are two main types of bore sights: muzzle-inserted and chamber-inserted. For muzzle-inserted bore sights, gently insert the device into the end of the barrel. For chamber-inserted ones, it's like loading a round into the chamber. Once inserted, the bore sight will emit a laser or provide a visual reference for alignment.

Step 4: Alignment - The Heart of the Process

Now, look through your firearm's sights or scope. You should see the reference point provided by the bore sight, be it a laser dot or another marker. Adjust the cross hairs or sights to align with this reference. This is where the magic happens: you're ensuring that your sights or scope align with the true center of the bore.

Step 5: Fine-Tuning - It's All in the Details

Once you've got a general alignment, it's time to refine. Make micro-adjustments to your sights or scope until they're perfectly centered on the bore sight's reference. Remember, patience is key. Small tweaks can make a big difference in accuracy.

The Benefits of Bore Sight: Why It Matters?

Bore sight offers several benefits:

  • Efficiency: In the world of shooting, every round counts, both in terms of cost and the wear on your firearm. Bore sighting dramatically reduces the number of rounds you'll need to fire when zeroing in your sights or scope. By starting with a bore sight, you're not just saving ammunition; you're also saving time and reducing the wear on your firearm. It's like having a roadmap before you embark on a journey, ensuring you don't waste fuel wandering aimlessly.
  • Accuracy: Imagine trying to build a house without first leveling the foundation. The end result would be skewed, right? The same principle applies to shooting. Bore sighting lays a solid foundation, ensuring that every subsequent adjustment you make to your sights or scope is more accurate. It's the difference between building on solid ground versus shifting sands.
  • Convenience: There's a certain satisfaction in knowing you can align your firearm's sights without firing a shot. Whether you're in a location where firing isn't feasible or you simply want to avoid disturbing the peace, bore sighting offers a silent solution. It's like tuning a musical instrument by ear; it requires skill, but the results speak for themselves.

Bore Sighting FAQs: Addressing Common Queries

What's the Difference: Sighting vs. Siting?

When it comes to firearms, words matter. "Sighting" a gun refers to aligning its sights for accuracy, while "siting" is about placement or location.

How Far Should I Be for Ideal Bore Sighting Distance?

The distance can vary, but 25 yards is common. Factors like firearm type, intended use, and bore sighting method can influence the ideal range.

Is There a Magic Yardage for Bore Sighting?

Typically, a range of 25 to 50 yards is suggested, but it's essential to consider the firearm's specifics and the shooter's comfort.

How Much Will Bore Sighting Cost Me?

DIY methods can be almost free, but professional services might charge between $20 to $50. Laser bore sights can range from $30 to over $100, depending on quality and brand.

Expert Tips for Effective Bore Sighting

  • Best Distance: For many rifles, sighting in at 100 yards is a good starting point. However, this can vary based on the rifle and ammunition.
  • Regular Checks: It's wise to check your zero periodically, especially if the firearm has experienced bumps or falls.
  • No Laser? No Problem: Traditional bore sighting, where one looks through the bore to align with a distant object, is still effective.


Bore sighting is an essential step for anyone serious about accuracy. Whether you're a seasoned shooter or just starting, understanding and utilizing bore sighting can make a world of difference. Do you have any bore-sighting tales or tips? Share them in the comments below!
