Top 10 Best Bore Sights (Jan. 2020): Review & Buyer’s Guide
- Erik Himmel
In my younger days, I have seen my father and uncles use optical sights to increase the zeroing factor of firearms. They always used to search for the top options on the market so they could hit the target more often than not. After college, I started to practice shooting as well and it was really a fun sport for me.
I had used different alternatives but I missed targets, I ended up wasting most of my rounds. Later a laser bore slighter changed my game. It helped me align the nozzle to the scope in a much better way as I could easily zero in the gunsight/iron sight efficiently now. Understanding the functionality of a boresight will help you in hunting or practice. Hopefully, this buying guide will provide you with the necessary information so you can choose the best bore sight for yourselves.

Nonetheless, we are not affiliated with any particular brand, instead, we maintain objectivity in our approach to picking the right products and detailing them in our reviews.
Why do you need a bore sighter?
Boresighter is a tool that allows the user to adjust the sight of optical firearms to assist in aligning it with the barrel's position or its bore axis. This is a pre-align method to increase the zeroing speed. This device takes less time to adjust and helps in aiming the target in shooting practice.
To choose the right one from so many options you need to understand technicalities of the device, including the material used, technology, design specs, cost, usage, accuracy, and other design aspects.
We made it easier for you as we have not only selected a better slighter based on the user experience but also on the technical level. It is better to read the entire guide before you invest your money.
Things to consider when buying a bore sight
For a common man, the description of a product is the main source of information. It will cover different aspects including information about materials, specifications, usage, unique factors, and other info. If you are not an expert, you will not understand whether the features are better or marketing gimmick. Still confused about what is the best laser bore sight? To reduce confusion, we have explained some of the key aspects below.
Being a modular gadget, a boresight is added to the firearm. This makes it obvious for its build to have high durability. Aluminum alloy is considered as the core building material as it not only ensures better durability but reduces total weight. Bronze is also a good choice as it provides a better balance to the firearms. Brass material is another material, which provides high durability along with compact and lightweight features.
There are majorly two types. The first type is a cartridge system, which is inserted in the chamber. It gives a laser beam and requires charging. The second type is the arbor type. It is attached to the muzzle. Cartridge type connector is more accurate compared to arbor type.
3. Laser specs
If you want high accuracy laser beam for excellent sight, you will need at least Class IIIA sensor. The better class will provide better output. You need to check the distance aspect based on your preference. Further, selecting an active beam laser helps in better sighting in the day time as well.
Is bore sighting accurate? Well, laser sighters should be accurate if you use them properly. A laser bore sight works the best for targets that are at a distance of 100 yards or more. They're easy to attach, easy to configure, provide better flexibility for different caliber and should last long. Universal sights are considered as the go-to options. But, some premium bore sighting laser devices can help in bettering the shooting experience with fewer parallax issues.
5. Versatility (More caliber vs Single caliber)
The sighters should handle single caliber and multi-caliber weapons. As the speed of firing varies, the adjustment or zeroing also varies. As a result, target locking should be perfect. It should be compatible with all kinds of guns as it is not feasible to buy separate models for each gun.
Fitting is a major aspect. A lightweight, durable and easy to mount sighter will allow the user to control the zeroing aspect properly. I did face issues with fitting as there were very few options for my gun. Now, there are so many options. Better fitting will definitely increase the aim output. Our review will help in understanding the fitting issue. Besides, you can also use a DIY laser bore sight to fit it correctly to the firearm.
Price should be flexible. It is better to set a budget and then set up an offset of 5% to 10%. This allows you to control and filter your buying options. This is just a suggestion as it helped me in finding the right sighter. Usually, the price of boresight ranges from 13 to 260 USD.
How did we pick these bore sights?
Initially, our team spent around 28-hour online research before extracting 20 highest rated bore sights from the most reliable brands at the time of our research. We field-tested each model for a period of two weeks. The Ranger Expert squad and a group of volunteers did the hands-on testings.

We reached out to the industry experts for their opinions on our choices. That reconfirmed our final ten list to be the top choices from expert's perspectives as well.
Our extensive research work and relentless testing will be paid off if our audience find them useful when making their buying decisions. Our buying guide might not match everyone's expectations, but it will never disappoint you if you find your choice here.

The case looks very premium and compact in size. Graduation scale is measured at 4.0 inches for every 100 yards/300 feet.
One major aspect is it includes three expandable and compatible arbors. This is really great considering the price. Arbors can also cover the calibers from 0.22 caliber to 0.45 caliber. However, they could have used better quality or grade laser sighter such as IIIR for professional use. This would have been a great feature.
