Which boresights are best?

In the past, the process of sighting in your rifle scope required hours of shooting and copious amounts of wasted ammo. Thankfully, modern technology has led to the creation of the boresight. 

These handy devices quickly attach to your rifle and emit a high-powered laser beam, allowing you to accurately line up your rifle scope without firing off a bunch of ammo. Designed to improve your shot accuracy, a high-quality laser boresight is the best way to improve your outdoor experience without wasting time or money. If you are in the market for a durable one-shot boresight, check out the Aexon Absolute Zero Red Laser.

What to know before you buy a boresight


When it comes to boresights there are two main types: collimators or lasers. A collimating boresight is designed to sit in front of your firearm sights and project a grid pattern on the sight picture. This type of boresight does not require batteries to operate, but it can be pretty tricky to operate. Designed to make boresighting simple, laser-bore sights easily attach to your firearm and emit a high-powered laser beam onto physical or simulated targets. Since the laser beams are easily visible, this type of boresight tends to be the most accurate and offer the best, real feel when it comes to lining up your scope and shot accuracy. 

Attachment style

No matter what type of boresight you chose, you need to be sure to choose an option that features a secure attachment style. Typically there are three different types of bore-sight attachment styles to choose from; magnetically mounted, arbor-mounted or chambered devices. 

  • Magnetically mounted: Designed to connect to the muzzle of your firearm, magnetically mounted boresights offer the easiest installation without sacrificing shot accuracy. However, be warned that magnetically mounted boresights accuracy is dependent on level of the rifle bore. While most rifle bores and barrel crowns are perfectly perpendicular, an older or damaged rifle may have some deviation, which would negatively impact the accuracy of the boresight. 
  • Arbor mounted: Inserted directly into the rifle bore, arbor mounted boresights have an expanding collar that holds the boresight in place. While some may be a bit apprehensive about inserting something into their firearm, arbor-mounted boresights do tend to be the most accurate when it comes to lining up your point of aim and rifle scope. However, arbor-mounted boresights do require caliber adapters depending on the type of gun you are using. 
  • Chambered devices: Ideal for handguns, chambered boresights are designed to resemble the caliber bullet for your gun. These devices can be inserted directly into the chamber and are relatively accurate when it comes to lining up firearm sights. However, you will have to buy different types of chamber boresights if you are looking to sight in multiple guns of different calibers. 

Your gun

The most important factor to consider when choosing your boresight is the type of gun you have. If you have a hunting rifle, then an arbor or magnetic mount boresight may be best since they offer the best resemblance to a rifle scope. Handguns using a chambered device may work best since they offer the best firearm sight practice while also allowing you to improve your shot accuracy without wasting ammo. 

What to look for in a quality boresight


To ensure the best experience opt for a boresight that features a high-powered and highly visible sight-in system. No matter the type of attachment style of your boresight, you need to be sure that the boresight you chose will be able to hold up in both outdoor and indoor environments.  

How much you can expect to spend on a boresight

You can expect to spend anywhere from $30-$150 on a high-quality boresight.
