Best Laser Bore Sighter Reviews and Buying Guide

In the old west sighting a gun required a keen eye and a lot of experience. Most of us have seen an old western or two with a sharp shooter sitting on top of a rocky outcropping staring down the barrel of their rifle at a distant target with one eye closed steadying their aim before unleashing a surprisingly accurate shot.

How successful these old cowboys really were is up for debate, but that was the reality of bore sighting before we came up with more sophisticated methods.

Technology has improved a lot in the last 150 years and there aren’t too many hunters these days that would really on their eyes and their instincts to sight the bore of a gun. Some use magnetic boresights, but laser bore sighters are the focus of this article.

These are extremely accurate little devices that can definitely give you an advantage when out on a hunt. In fact, there aren’t too many expert hunters these days that don’t use them.

A boresight is used to align your guns optical sight accurately with the bore of your gun so that you hit the target almost every time – at least you will if you’re a good shot.

Even the best sharp shooters will have a difficult time finding the target if their weapon isn’t properly aligned. That makes a boresight an essential part of your hunting gear and laser sights provide the most accurate option.

While they may seem like a relatively small part of the puzzle, their importance can’t be overstated. Bore sighting is something you want to get good at if you’re going to have success on the hunt.

Below we cover some of the best laser bore sighters available then we’ll discuss what features to look for before you buy.

Laser Bore Sighter Key Features

Below are the key features to consider when buying or using the best laser bore sighters.

Calibre Specific

Some of the top rated laser bore sighters are calibre specific. This means you have to be careful when purchasing one as it won’t be much use to you if you choose a sighter with the wrong calibre for your firearm. That’s not a major issue for most, but it can be a bit of a pain if you own several different firearms of different calibers.

If you have to buy different bore sighters for each one of your firearms it can be a relatively expensive proposition. If on the other hand you’ve been using the same rifle for the past decade that’s probably not a concern and calibre specific sight are typically more affordable.


The whole point behind using a laser bore sighter is to improve the accuracy of your firearm so you you’ll want to ensure that it fits snugly and doesn’t move around at all. A laser may travel in a straight line, but if you’re off center before you even begin you’re defeating the purpose.

Accuracy is the single most important feature to consider when you’re selecting a bore sighter. If the sight you’re considering doesn’t have a stellar reputation for accuracy it’s not worth your money.

There are many different bore sights to choose from and a lot of them are quite affordable – you don’t have to settle to save a little money.

Ease of Use

There are some pretty complex bore sighters on the market and while they may be accurate, durable, and ideal for the expert – they may not be ideal for the occasional hunter. It’s almost always better to look for a device that’s easy to use.

If you’re using a calibre specific sight it should fit snugly and quickly into the barrel. The best multiple calibre bore sights are magnetic and simply fit onto the end of your rifle – no fuss, no muss.

Daytime or Nighttime Use

There are essentially two different types of lasers employed on bore sighters: red ones and green ones. The red ones are most common, but they are only really effective in low light situations. Green lasers are visible even in the middle of the day. Some of the better laser bore sighters have both red and green laser attachments. If you can afford one of these they are ideal and give you the best range of options for sighting your firearms.


Some laser bore sighters are designed to be used on multiple different calibre firearms. In some cases this is done by using different adapters that can screw on to the end of the sight and they still fit inside of the barrel.

Others are designed as a one size fits all option and attach to the barrel of your gun using a magnet instead of going inside the barrel. Both types can provide you with accurate sighting of your weapon and it really comes down to personal preference.


You should also take a look at the durability of the sight. Some of the more expensive laser bore sighters cost well over $100. That’s a fair bit of money to splash out on a little device that you’re only going to use for minute or two each time.

Some are made from brass and some are aluminum – either material can be very durable and it’s best to take a close look at the manufacturer’s reputation when making a decision.

Final Thoughts

Finding the best laser bore sighter for your needs is highly recommended and an essential piece of equipment in any hunter’s bag of tricks.

These little devices can significantly improve accuracy and they can last a long time if properly taken care of. There are both calibre specific and multiple calibre options.

Both do a good job and which one you choose really comes down to individual comfort. The main thing is to make sure you have a good one for your rifle and that you always have working batteries in it.
