In order to achieve the most accurate shot every single time, you need to complete a process known as bore sighting. This must be done on all weapons and it is mandatory for hunters and those who like target shooting. If we add the fact, AR15 is one of the best and the most popular weapons in the country, we can understand why knowing how to use laser bore sight AR 15 is an important skill. Below, we will guide you through the process and explain all the main aspects.


What is a bore sighting and why it is important?

Before you learn how to use laser bore sight[1]https://en.wikipedia.org/wiki/Boresight_(firearm) AR 15 you need to know why this process is so important. Basically, it is used to line the center of the barrel to the scope or sight of your rifle. As such, the accuracy is at the highest level possible. This is known as zeroing in and it is done by all experts and even beginners. It helps you get a more accurate shot, decreases wasting the ammo, and improves your success when hunting or when shooting in the targets.

There are two methods you can use. The first one is using your eye. You will need to remove the bolt and look through the barrel. Adjust the sight accordingly and you are done. But, this isn’t the most accurate method. A more preferable method is using laser sighters.
In general, you can use both of these methods. However, when it comes to AR15, the latter is more appealing. This rifle doesn’t allow you to remove the bolt and look through the barrel in seconds. This is a complicated process. On the other hand, using a laser sighter is much easier, simpler, and more accurate.
