If you have ever been in a situation where you’re sighting in a pistol or rifle, but you seem to be using a whole lot of ammunition to do so, it might be time to pick up a bore sight and learn how to bore sight a rifle. Most of the bore sighters on the market today make sighting simple by including a laser.

Laser bore sights are a common staple for those who own firearms as they allow you to quickly and easily sight in without heading to the gun range.

This gives you the option of sighting in a rifle at home no matter what the weather looks like outside.

Because of how helpful these sights can be, having one is something every firearm owner should consider. Today we’re going to be looking at eight of the best laser bore sights on the market and explaining exactly what they offer you.

Things to Consider When Choosing a Laser Bore Sight 

Just looking at our reviews of the best bore sights on the market, you have probably come to realize that these devices come in many shapes and sizes. While all can do the same job of making sighting in a firearm more easily, they often use different features to do so. This can make it more difficult than expected to find the bore sight that is perfect for your situation.

We’re going to offer a bit of information about the different features and characteristics of bore sighters and how those things can impact your experience. This should give you a great start for finding the model that best fits your needs.

Type of Laser Offered 

Knowing which kind of laser a bore sighter has is extremely important when it comes to how you can actually use it. Every laser manufacturer is a bit different and some may be better for your needs than others. There are a few different things to be aware of when considering a bore sight and its included laser.

Laser Class 

One of the ways you can determine the quality of the laser is by looking at the class. Many of the bore sighters on the market have a class III laser, but there are a few that use higher quality ones. If you aren’t familiar with laser class, it affects how visible the laser actually is.

A laser with a lower class is going to be more visible in all situations. Lasers with a high class are also considered to be more dangerous for your vision. However, class III lasers are considered to be among the safest.

Laser Color

When you see a bore sight mentioning a laser color, you might think that the choice is arbitrary, but it is anything but. It is a good rule of thumb that green lasers tend to be easier to see than red lasers will be. This may not be the case 100% of the time but it’s fairly close.

Green lasers are more powerful in most cases, whether because they run on a different wavelength or because they are in a different class. In addition to that, the human eye is better that spotting the hues of green than with red. If you choose a green bore sighter, this will allow you to zero in your optics and sights over a longer distance than with a red laser.

Laser Brightness 

You can have two lasers that are exactly the same class, but where one is brighter than the other is. The best option is to choose a laser that is very bright as it makes zeroing in your firearms easier when it’s sunny outside. If that isn’t possible, you will need to zero in on a clouded day, an evening, or inside before you get started.

Versatility Offered By a Bore Sight

You may notice that some of the lasers on our list can be used on many different weapons of various calibers, while others must be used only on a single caliber. There are other differences as well, some of which you will want to think about before purchasing the right bore sight for yourself.

Additional Calibers

If you go for a unit that fits more than one caliber, it will typically come with several adapters that let it fit the barrel of additional firearms. Every time you use the sighter on a new firearm, you will need swap out the adapters. This might sound frustrating, but it really doesn’t take much time.

When you get a bore sighter with multiple caliber fittings, the sighter will come with everything you need to do so. In many cases this will be a simple single screwdriver.

Keep in mind that while this kind of sight is often reliable and precise, it may not fit flash hiders or muzzle breakers so not every rifle in your arsenal may be able to use them.

You also have to remember each and every time to change the adapter between firearms. That means unscrewing the current one and mounting a different one in its place. This involves using a small screw to screw the adapter to your sighter. This can be difficult in situations where there is little light.

There are a few models that allow the use of the bore sight on separate firearms without using screws that you might drop and lose. Some have a magnetic platform that attaches to the barrel. This is the most convenient option.

Single Caliber

On the other hand, a single caliber device is going to be the simplest to use. Since they are created for a single caliber, there’s no need to worry about adapters or screws. As soon as the bore sight comes in the mail, you can begin to use it.

Two types off single caliber bore sighters are available on the market. One is like the multiple caliber device in that it attaches to the barrel of a firearm using a magnetic platform or sliding right into the barrel. The other is more like an actual firearm cartridge which loads into the chamber and shows exactly where your gun is aiming.

Price Considerations 

As with any other product you decide to purchase, laser bore sighters are going to come in many different price ranges. This might seem strange as they all do the same thing. However, there are reasons for the price variance which we will share so you can ensure you are purchasing the right product for your specific needs.

Inexpensive Models

Most of the models that are least expensive are going to be class 3B lasers. These lasers are considered to be safe but are just on the edge of that. This means you should avoid staring directly into the light from the laser. When designed for use on a single caliber, they will have a simple design that makes them efficient for use, despite their low price.

The lasers on most of these lower end sights are going to be red, which works well in situations with low light but may not be easy to see under bright daylight or artificial light. This is a disadvantage, but the lasers are still completely usable indoors or under dim light.

Those that have a versatile design to work on multiple calibers tend to make use of screw on adapters. This makes it more challenging to switch them out in the field, but it can still be done.

Mid-Priced Models 

When you choose a mid-priced bore sight, you are often going to get a higher quality laser than with the inexpensive models. Most of the time these lasers will be more power efficient, which means the batteries last longer, as well as being safer in general.

While most of these models will use red laser light, the laser tends to be brighter so you can see it from farther away. Those with multiple caliber fitting may use high quality adapters or magnetic platforms so swapping them out is a bit easier. The ones that are single caliber tend to be very accurate.

High End Models 

The more expensive bore sights tend to be equipped with green laser light, which makes them easier to see in all sorts of light conditions. Most of them will be multiple caliber so you can easily use them with many firearms. The sights in this price range tend to offer magnetic platforms so swapping them out is the easiest of all.

In addition to offering lasers that are more visible, they tend to be the most power efficient so the batteries will last a very long time. This can be the most useful if you have several firearms that use separate sights and scopes that you rotate throughout the year. It also works well for professionals who don’t want to deal with a lot of maintenance.

How to Use a Bore Sighter 

If this is your first time using a bore sighter, you want to know how to actually use it. It’s a lot easier than you might think. There are six steps involved and each will only take a short amount of time to get through.

The first thing you want to do is make sure your firearm is unloaded. Then you want to set up a sack of sand, bipod, or some other target at some distance from where you will be using the sight.

Next, install the bore sighter and zero the optics of crosshair on the laser.

Once that’s done, remove the sighter and load the gun. Then fire one single round at the center of the target.

Unload your gun once more and put the sighter back on. Look through the optics or sights and adjust them so the sighter is centered right on the target with the crosshairs on the hole the bullet made in your target.

Take off the bore sight one more time and load your firearm.

Shoot at the center of the target. If all went well, this shot should go right through the center. If that isn’t the case, start back with step four and go through the rest of the instructions again.

The Top Bore Sights of the Year 

At this point, you should have the knowledge you need to choose the right bore sight for yourself. A laser bore sighter will help make zeroing in your firearms a breeze. It makes the process easier as well as very precise.

Follow our instructions for how to use a bore sighter and you will quickly be able to zero in using only a couple of bullets rather than many more.

It isn’t that challenging to find the best bore sighter when you have the knowledge about what to look for. This buying guide will help you make the decision about which model is best for you.
