What is a Bore Sight and What Do They Do?

A bore sight is designed to help you line up your scope and sights perfectly so you can be able to hit your targets consistently with accuracy and precision. Using a bore sight will help you determine whether or not your current settings are perfectly aligned or if they are slightly off in either the upward or downward direction. Then, you’ll need to be able to make the right adjustments until it’s lined perfectly with your target.

Types of Bore Sights

There are a few popular types of bore sights that are often used by so many rifle owners. Each bore sight has its own unique features and functions but serves the same purpose in making sure that your sights and scopes are lined up so your aim is perfect and not off. The following are the types of bore sights currently on the market:

Collimators and Arbors

These types have been around for decades. Arbors and collimators are two accessories that work together to ensure that you’ll have a much better aim. Arbors or “spuds” are small barrels inserted into the muzzle of your 9mm AR rifle of choice. A collimator is a graph paper-like device that you can use while looking through the scope of your rifle. These are even more effective when you’re trying to adjust the scope’s windage and elevation settings.

Sightmark 9mm Luger Boresight

Magnetic Bore Sights

These include strong magnets that will make it easier for you to attach to your muzzle. These are made to fit many calibers and rifle types, especially 9mm AR rifles. These will definitely come in handy whenever you want to check your zero after a long day of transporting your rifle. If you need to double check how your zero is holding up once in awhile, a good magnetic bore sight might be your best choice.

Laser Bore Sight

Laser bore sights are obviously easier to use. But they do require some reflective targets in order for them to work effectively. Once again, these bore sights are rather easy to insert into the muzzle of your rifle, so you won’t need to worry about whether or not it will be a struggle to tack it on.

Aspects to Consider Before Buying

While you’re looking for a 9mm AR bore sight of your own, it’s important to consider some of the aspects that will weigh into your final decision. At the same time, you’ll need to know which characteristics are key in what makes a bore sight stand out. Here are some aspects that you should consider while looking for a bore sight:

Price

If you’re a budget shopper, you will likely hold the price to a higher priority. However, you should always make quality a high priority as well. That’s because the latter is much more important.

If you’re on a budget, find the best quality bore sight that is within your budget range. Even if you spend something that’s high on your desired budget scale, it’s way better to spend a little extra than on something that’s cheap and disappointing.

What Type of Bore Sight Do You Want?

Your decision will boil down to this question: what kind of bore sight will you need for your personal use? Are you looking for a laser bore sight or a magnetic bore sight? You’ll need to find which one will work easier for you so you can use it to your advantage.

Material

As mentioned earlier, quality should be a high priority on your list. What better way to determine which bore sight is high-quality than finding out what kind of materials it’s constructed from. Most bore sights will be made from high-quality materials like steel to ensure that not only it’s durable but stands the chance of lasting you a very long time.

Review of the Best 9mm AR Bore Sights

Below are five of the best 9mm AR Bore Sights that are currently on the market. While you’re looking through each one, it is important to note the characteristics and functions. This way, you’ll know exactly whether or not it will match your ideal bore sight.

Once you find a winner, you’ll be closer to making your rifle more accurate than ever. Now, let’s kick off our list by revealing our “best overall” choice for best 9mm AR bore sights:

Pros

  • Easy to Insert in the Muzzle
  • Very Portable, Can Fit in Your Pocket
  • Allows For Better Accuracy For 9mm AR Rifles
  • Laser Beam is Very Visible, Especially in Daylight
  • Very Lightweight, No Additional Weight Added to the Rifle

Cons

  • None

What Recent Buyers Report

Most recent buyers were able to easily attach this bore sight to their muzzles. Once installed, they were able to use the laser sight on a bright sunny day. The sight allowed them to align their scopes and sights with such precision. Even some users have relied on this for when they want to check to see if their zero is still intact.

Why it Stands Out to Us

One reason why we chose this was due to the fact that the laser beam is actually visible in broad daylight. This makes it a step ahead of other laser bore sights that fail to be visible in such conditions. Aside from that, it’s an easy to use bore sight that will take minutes to help you get your scope zeroed in and ready to go.

Who Will Use This Most

Since it has a range from 15 to 100 yards, this will probably be used by target hunters and competitive shooters. But don’t count out the hunters as well. All three applications place a high value of importance on accuracy. If you fit into this category, you’ll find yourself using this bore sight as well.

What Could Be Improved and Why

One of the things that might improve with this bore sight would be increasing the battery life. The battery is said to last an hour, but it may not be enough for those who are constantly trying to sight in their scopes. So a slightly more powerful battery could be needed in order to meet such an improvement.

Bottom Line

If you’re looking for one of the best 9mm AR bore sights in the business, the Sightmark 9mm Luger Bore Sight might be your best option. You can simply install it and zero in your favorite 9mm AR in a matter of minutes. Once all is said and done, you’ll be able to fire off one scary, accurate beast at the range. 

Pros

  • Adapters Are Easy to Use.
  • Adjustable to Accommodate All Kinds of Calibers
  • Laser Beam is Quite Bright, Can Be Visible in Daylight Conditions
  • Super Durable, Doesn’t Break if You Accidentally Drop it On the Ground
  • Very Lightweight, Doesn’t Add On Any Weight to the Front of the Barrel

Cons

  • Battery Life is Short, Some Report it Dead On Arrival
  • Some Fitting Might Be a Challenge For Some Calibers
  • Some Have Struggled to Keep the Bore Sight in Place

What Recent Buyers Report

One recent buyer said that this was the most flexible bore sight he’s seen. Not only has he used it on his 9mm AR, but he has used it on other rifles. It’s easy to adjust and will fit different calibers with little issue. He says that from here on, it’s his “go-to” choice for bore sights.

Why it Stands Out to Us

This is a small bore sight that you can take with you just in case you need to make sure your shots are lined up perfectly. Sometimes, the thought of whether or not we’re shooting straight will cross our minds (don’t think that’s never happened to you).

This way, you’ll be able to use it on the go and be able to zero in and make adjustments if necessary. Just be sure to have some paper targets on hand in case your out in the woods and not at a nearby range.

Who Will Use This Most

The most likely users will be casual target shooters and hunters. Especially if they’re looking to sight in their rifles from 100 to 200 yards out. For a rifle to have quite a bit of reach, it does come down to finding the right bore sight to make sure your shots are accurate for targets at that distance.

What Could Be Improved and Why

Once again, we revisit the battery issue. Only this time, we’re talking about a new bore sight. Find a battery that is the same size and is a bit more long-lasting. Otherwise, do away with the battery altogether so a user can find a battery of their own to ensure that the laser will last longer. 

Bottom Line

If you’re looking for a laser bore sight that will work with so many different rifles, you’d be hard pressed to find anything quite like the Laserlyte. Once you have this added on, you’ll be able to use it for one rifle and end up using it for a few more. It’s that darn reliable and will definitely make your shooting considerably better. 

Best for the Money:
SiteLite Mag Laser Boresighter

SiteLite Mag Laser Boresighter

Pros

  • Excellent Quality
  • Can Fit Most Calibers
  • Great For Both Pistols and Rifles
  • Laser Beam is Quite Bright For Most Targets
  • Lifetime Warranty Available if Something Were to Happen to it

Cons

  • May Not Work For Glock-Style 9mms
  • Batteries May Arrive Either Weak or Dead
  • Some Have Complained About the Laser Not Being Bright Enough 

What Recent Buyers Report

Most recent buyers were able to use this bore sight without any issues with the fitting. Some of them have elected to dig out the battery it came with and replace it with a more powerful battery (i.e.--longer lasting). This was a favorite among 9mm AR users and also those who have different caliber rifles. The bore sight is also a favorite among pistol owners as well.

Why it Stands Out to Us

For something that is considered affordable, it’s solid in terms of construction. Performance wise, it does a great job aiding you in sighting in your scopes and making sure that each and every shot you get off is straight, precise, and accurate. This is as close as your going to get to a versatile bore sight since it will work with both rifles and pistols.

Who Will Use This Most

This might be the closest you can get to a universal bore sight. It will be used by those who will either have a 9mm AR or any rifle or pistol of any caliber. This will have the ability to fit any caliber. If you have multiple firearms that you can zero in with ease, this might be the bore sight that can handle it all.

What Could Be Improved and Why

One of the things that we think can improve is making sure the laser is visible from a much farther distance. Some have reported seeing it as far as 25 yards out. Making it go out a little farther can make zeroing your rifle in beyond that a lot easier.

Bottom Line

If you’re looking for a bore sight that will work to your advantage for any rifle or pistol (including your 9mm AR bore sight), then you’d be insane to pass up the opportunity to look at the SiteLite Mag laser bore sight a little further. This might be the last one you’d ever buy for a while for a few good reasons. One, it is quite durable and two, it fits almost any rifle or pistol you can think of. What more can you ask for?

MidTen 9mm Bore Sight Cal Red Dot Boresighter Rem Gauge with Three Batteries

Pros

  • Easy to Install in the Muzzle
  • Easy to Add Batteries in the Compartment
  • Laser is Quite Bright Up to a Certain Distance
  • Allows Quick Sighting in of Your Rifle Scope or Pistol Sight
  • Excellent for Red Dot Sights that can Reach Out to 50+ Yards

Cons

  • Some Fitting Might be Required
  • May have a Hard Time Ejecting When Finished
  • Some Complained About the Laser Beam Pulsating Erratically

What Recent Buyers Report

Most recent buyers were able to add this onto their muzzle with no trouble. The batteries were decent and were able to last them quite a while. Most users were able to sight in their rifles and pistols in a matter of minutes. One user said his 9mm AR pistol was sighted in within 10 minutes.

Why it Stands Out to Us

At this point, you probably assume that we’re not too crazy about the idea of having batteries included. This bore sight proved us wrong. It’s convenient that these come with three batteries that actually have a decent life. This blows the competition out of the water in that regard.

Who Will Use This Most

This will likely be used by those who are getting tired of dealing with short-lived batteries. This sight will also be used by shooters who want nothing more than to quickly zero in their rifle or pistol and be done with it. If you hate wasting time with ineffective bore sights, this one might be right up your alley.

What Could Be Improved and Why

A potential improvement that we can address is making some adjustments to the end of the bore sight so it won’t risk getting stuck in the muzzle. The reports on this were few and far between, but it still might be expected for some users.

Bottom Line

This bore sight actually has included batteries that work. That is a win for you if you just want something to work right out of the box. The MidTen will definitely give you a better chance at shooting more precise and accurate shots on your 9mm AR rifle or pistol, even with targets situated from 50 to even 100 yards out.

G-Sight Firearm Dryfire Laser Training System with Cartridge, Tripod, and App

Pros

  • Affordable for Most Budgets
  • Perfect For Training Applications
  • Works Well as a Starter Bore Sight
  • Keeps Shots Straight Through 500+ Rounds
  • Laser is Really Bright, Can Be Visible at Various Distances

Cons

  • Some Fitting Might Be Required
  • The App Might Need Some Improvements
  • Might Be a Challenge to Insert and Even Remove

What Recent Buyers Report

For most recent buyers, this was their first ever bore sight. Overall, they were quite satisfied with it and found it easy to use. This was excellent for sighting in rifles that were best used in target shooting and competitive shooting situations. The sighting-in process was quick and took no more than 10 minutes for most users.

Why it Stands Out to Us

This is the one bore sight that uses the power of a mobile app. Who knew you could use a bore sight with just a touch of your phone. Either way, it’s interesting to see how it works out with something like a bore sight of all things. Modern technology...meet your newest friend.

Who Will Use This Most

Anyone who has never used a bore sight before in their lifetime. This is as close as your going to get to a starter bore sight. You’ll learn the ins and outs of how it all works with the use of the app. In the future when you find a new bore sight to work with, you’ll know exactly what to do.

What Could Be Improved and Why

The app might be an interesting feature, it will improve over time. One thing we’d like to see is real-time measurements so you can make some adjustments to your scope’s windage and elevation. This way, you can be really precise with not just your shots but also with the exact MOAs with your scope adjustments.

Bottom Line

If you’re looking for a bore sight that is something that you might say is “21st century” compatible, then the G-Sight Luger Training Laser might be your cup of coffee. If only the rest of the bore sights would get with the times and get an app of their own.

Conclusion

The best 9mm AR bore sight is out there. Eventually, you might own one of the five listed above. Be sure to find out which one is more your style and once you have it in your hand, you’ll want to give it a whirl at the range.

Remember, this is a bore sight that’s going to stick with you in the long run. So find one that is reliable and actually gets the job done by making your shots more accurate than ever.

How Many Yards Do You Need to Bore Sight a Rifle?

To begin, you should start at 25 yards with paper targets. Then you can move up to 50 yards once you are able to consistently hit the bullseye from that distance. Do this until you are able to reach 100 yards with consistent bullseye hits.
