Laser Bore Sighter Buying Guide
As you could see from our short reviews, bore sighters come in different sizes and shapes. Even though they are used to provide the same results, they use different features to do it. This is why finding the best laser bore sighter might be more difficult to do than you would expect.
In the following section, we take a look at how the characteristics and features of a bore sighter can influence your experience, and we explain how to find the right model for your needs.
Type Of Laser
The type of laser the bore sighter comes with is really important in how you can use the unit. Not all the lasers manufacturers use are the same, and some are better than others. Here are some characteristics you should look for.
- Laser Class – The class of the laser is one way of determining its quality. Most bore sighters come with class III lasers, but there are some models that use better ones. The class of the laser affects the laser’s visibility, and the lower the laser class, the more visible the laser will be. Higher class lasers are also more likely to be dangerous for your vision, but class III lasers are considered safe.
Laser Color – The color of the laser might seem like an arbitrary characteristic, but it’s anything but. As a rule of thumb, you will be able to see the green lasers better than the red ones. For one, green lasers are often more powerful, whether they’re in a different class or because they’re running on different wavelengths. Another reason why green lasers appear more visible to us is that our eyes are capable of spotting the different nuances of green better than they do red. Using a green bore sighter will allow you to zero in your sights and optics over longer distances (you will need a rangefinder as well).- Laser Brightness – Even if they belong in the same class, some lasers are dimmer than others. It’s ideal to find a bright laser because that will allow you to zero in your firearms in broad daylight. Otherwise, you will either have to zero in your sights indoors, or you have to wait for a clouded day or for the evening to come before starting.
Versatility
As you could see from our reviews, some laser bore sighters can be used for more calibers, while others can be used for a single caliber. Here are some of the differences you’ll notice when using the two types of sights.
- More Calibers – The units that can be used for more calibers usually use different adapters to fit on the firearm’s barrel. These adapters have to be changed every time you want to use the sighter on another firearm, but luckily, they’re not difficult to change. The bore sighter will come with all the equipment you’ll need to change the adapter, which in most cases be a single screwdriver.
Even though these models are usually precise and reliable, their design might not be compatible with muzzle breakers or flash hiders, so you might have some problems adapting them on all your rifles.
On the other hand, every time you have to change the adapter, you will have to be careful to unscrew the adapter that’s currently in use and mount another one in its place. This is done by screwing the adapter on the sighter using a small screw. Needless to say, this might be difficult to do in the field, especially if you’re using the sighter at dawn or in the evening light when the laser is more visible
However, there are some versatile units that can fit on multiple caliber rifles without having to use screws. Models like the Sightmark Universal Bore Sight use a magnetic platform to attach themselves to the rifle’s barrel. This will allow you to zero in the sights of different firearms without having to deal with all the screws and adapters.
- Single Caliber – Single caliber laser bore sighters have the advantage of being very easy to use. Since they’re not supposed to be used on different caliber firearms, they don’t come with screws and adapters, and you can use them as soon as you open the box.
There are two kinds of single caliber bore sighters. Some of them attach themselves to your firearm’s barrel, just like the versatile models. They either use a magnetic platform or simply slide into the barrel without any problems. Other models, such as the Sightmark Rifle Boresight, are designed to mimic the real cartridges. These units can be loaded into your rifle’s chamber, and they will show you precisely where the rifle is aiming.
Both of these designs are easy to use, and they can be very precise.
Price
Just like with every other product on the market, laser bore sighters come at different price ranges. And since most of them do similar things, you might be wondering what the price differences are all about. Well, let’s take a look at how the price influences the performance when it comes to laser bore sighters.
- Cheap Models – These models usually use class 3B lasers. While these lasers are considered safe, they’re right on edge of the safelight spectrum, so it is advisable to avoid staring directly at them. If they’re designed to be used on a single caliber, they have a simple design that makes them efficient, despite their low price.
The laser emits a red light that’s visible in low-light conditions, but not very visible in broad daylight or bright artificial lighting. While this is a disadvantage, you will still be able to use them with good results indoors or when the light is dim.
If they have a versatile design, and you can use them on multiple calibers, they usually come with screw-in adapters. This makes them more difficult to adapt to the field, but they can be efficient, nonetheless.
- Medium-Priced Models – Medium-priced models usually use better lasers than the cheap ones. The lasers they use are not only safer, but they’re also more power-efficient, so their batteries will last for a long time.
Even though they use a red light, the laser is brighter, so you will be able to see it from a greater distance. If they have a versatile design, they might come with ingenious adapters or magnetic platforms that will allow you to use them on different models without too much trouble. If they’re designed for a single caliber, they’re highly accurate.
- High-Priced Models – These models usually use a green laser light, so they’re easier to spot in all types of light conditions. They are usually versatile, so you can use them on multiple firearms. Even though they’re versatile, they come with magnetic platforms that allow you to use them in the field without too much fuss.
Not only do these models use more visible lasers, but the lasers are also more power-efficient, so their batteries will offer a long lifespan. This is especially useful if you have multiple firearms that use different scopes and sights you rotate during the year. This can also be very useful if you’re a professional or amateur gunsmith, as it will lower the unit’s maintenance.
How To Use A Laser Bore sighter In 6 Easy Steps
Now that you know how each characteristic can influence your experience and you can choose the right model for your needs, let’s take a look at how to use a laser bore sighter.
- Unload your gun and set up a bipod or a sack of sand at a certain distance from the target
- Install the bore sighter and zero the crosshairs or optics on the laser
- Remove the bore sighter, load the gun, and fire a single round aiming at the center of the target
- Unload the gun and install the bore sigher again. Look through the sights or optics and adjust them so the sighter is still centered on the target, but the crosshairs are centered on the entry hole the bullet made.
- Remove the boresight and load the firearm again.
- Shoot aiming at the center of the target. The shot should pass straight through the center. If it doesn’t, repeat paces 4 – 6.
