A bore sight is mainly used to align the barrel of a Firearm with the target in question. While traditional bore sights used cross hairs which could be aligned on the target, the more modern method is to use laser bore sighting to perfect this alignment.
How Does Laser Bore Sighting Work
In this method, the laser illuminates the target, and this makes it more effective and correct than visual sighting. The laser dot that is illuminating the target can be fixed to the target, and yet allow the Firearm to be moved. The simple theory behind laser bore sighting is that it aligns the optical sight that you are using, with the axis of the bore of the Firearm you are using. So you can do this without spending on ammunition to test accuracy. Laser sights are part of casings that can fit the barrel of the Firearm in question. So when you point at a target, the laser beam is completely aligned with your Gun barrel and you can adjust the sights and align the Gun properly on the target. You then do not need to fire a bullet to ensure that your alignment is correct. This c an result in savings in ammunition costs.
Choosing:
The extreme compactness of utilizing a cartridge laser bore sighting that is inserted in the magazine, allows it to be carried around easily by any law enforcer or sportsman and most models guarantee accuracy. The cartridge style is meant for specific calibers, but comes with a complete guarantee of accuracy, because it remains perfectly aligned with the barrel of the Gun. However these bore sights do require batteries to power them and this does not allow them to be used in very small caliber revolvers, as the size of the battery will not allow this. There are also boresighters that can be inserted into the muzzle of the Firearm instead of in the chamber. However these do require that the barrel length is at least 4 inches in length. These laser bore sightings will have an external battery source that is connected with a wire. They are also available with a collimator that can be attached to t he barrel of a firearm. This attachment is done with magnets or other devices. Most devices will come with red lasers, but you can also opt for those that have green lasers which are visible for greater distances.
Using:
Immaterial of the type of laser bore sighting, the use of them is the same. While cartridge type laser bore sighting are specifically meant for certain weapons, the other boresighters are universal and can be used with almost any type of firearm. It is best to hold the Gun or firearm firmly in a Gun rest when you are making the alignments. Project the laser on to the target and then adjust the sights or cross hairs of a scope till they are in perfect alignment with the laser. While making such adjustments does increase the chances of accurate shooting, this is no way a guarantee that you will hit your target every time, but will definitely increase the chances of doing so, as your firearm will have no alignment inaccuracies. When you are shooting outdoors you still have to contend with bullet drop and wind factors, especially for long distances.
Laser bore sighting can improve the accuracy of a weapon. Law Enforcers, Tactical Teams and Special Ops will do well to make it part of your armory. It can help your shooting.
