Key features to consider when choosing a bore sighterBoresighter attachment mechanism

This consideration typically has three categories to consider:

Cartridge bore sighters

They are calibers inserted into the gun chamber and will illuminate once the bolt is closed. The main drawback of using this kind is that the custom settings may limit usage in a particular variety of guns. They are loaded just the same way a bullet is loaded.

Muzzle inserted bore sighters

These require insertion at the calibers or muzzle and are economical because they may work excellently in different firearms though that may depend on the adapter and o-ring being used. The only issue that may arise with the kind is that the bore sighter’s stem might be long for some guns.

Magnetic attachment bore sighters

These are super-flexible since they’re meant to be used on all firearms that are made of magnetic metals. These might be quite expensive owing to flexibility in their usage, though they can be handy for someone who uses different types of rifle and guns for different purposes. They can save a lot of cash since once won’t be required to buy a different bore sighter that fits the kind of gun they wish to use.

Boresighter functioning mechanism

When it comes to the functionality, there usually are two main categories which include:

  • Mechanical bore sighters

These are somehow frequent, and they use a number of arbors that are made with a defined size for every caliber. Once you’ve selected the right arbor and put it in the muzzle, you can then attach and align the bore sighter to the arbor.

  • Laser bore sighter

This one works by projecting a dot on a target, then aligns your sight with the bore and the dot.

Nature of the laser for laser bore sighters

The nature of the laser, in this case, may refer to things like the color, illumination distance, and the size of the beam. As for the color, if you’ll be using the bore sighter mostly during the day, you might want to go for green which brighter during the day, though more expensive. Of more importance, however, should be the illumination distance, and for such a case, red lasers carry the day. As for the size of the beam, either red or green lasers may be large or narrow, but make sure you go for the narrow diameter for better chances to zero in on your target.

Boresighter lifespan

These devices are made from varying materials, including brass, aluminum, iron, and other metals. The sensitivity of the device, however, should discourage you from getting one that is prone to corrosion. Aluminum can be a good choice since it’s easy to handle as well as resistant to corrosion. The lifespan of the device will also depend on how careful you are when using it.


Accuracy is the most important factor to be considered since it’s the reason behind the use of a bore sighter after all. As such, you have to ensure that the device fits snugly and doesn’t move at all, affecting the accuracy. Accuracy should be the single most significant feature to be considered, and if the device you select doesn’t meet a perfect accuracy reputation, then you should know that it’s not worth spending a coin on.

Ease of use

Always ensure that you go for a bore sighter that is easy to use, depending on what kind of gun you want to use it on, as well as the skills that you have. Some of these devices are far much complex for a typical hunter and are best suited for use by experts.

In summary

The good olden days when one would use the closed-eye technique and their instincts to hit a target are gone, and technology has taken up the responsibility of ensuring that you never miss your goal, no matter the situation. Finding a good bore sighter would be the best thing a hunter would do to avoid wasting a lot of money, time and effort trying to get a catch, to end up getting frustrated. As you sight your rifle, however, remember to keep it unloaded, and ensure the muzzle faces the safe direction. Once you’ve done everything in the right way, you can be sure to hit your targets right every time.
