What is Boresighting?
Boresighting is a method used to line up the firearm barrel and sight by adjusting the optical firearm’s sight. It makes zeroing in much faster. So a bore sighter is very much necessary to complete the action.
It makes the tedious process of sighting in firearms easy with laser bore sights. Simply attach the boresight onto your firearm and calibrate your rifle to a target at a set distance. So, you can adjust your firearm accordingly to make a single shot.
It has an optical head and a bore-diameter arbor that is placed into the muzzle of the rifle. The optical head is attached to the end of the rod, while the grid pattern of it helps to line up the sight with the barrel.
Different Methods of Bore sighting:
Bore sighting provides you with a reference point from which you have to start sighting in your gun. This saves your ammo, time, and also protects your shoulder from unwanted recoils. Bore sightings are of four types based on technological developments. They are;
1. Traditional bore sighting:
It is the oldest method where the bolt is removed on a rifle to sight down the bore of a gun at a specific point of the target beyond 50 yards. Here, the windage and elevation turret of the scope or iron sight is adjusted to aim the center of the distant target once the rifle is held in place. This method is mostly done in handguns.
2. Collimator and Arbor Sighting:
This is another oldest but efficient method of boresighting. Here, the collimator and arbor are used for sighting. The collimator is a device with a paper-like grid in it and you can see it through your scope. It is secured in place by the arbors present inside your barrel from the muzzle end. A spring holds them in place and they are sized according to your caliber. Then you have to adjust the windage and elevation turrets by looking through the scope. Size the arbors precisely to make a single shot. Most of the collimating boresights feature many arbors.
3. Magnetic Boresighting:
This is the most convenient method of boresighting. You just have to attach the bore sighter to your muzzle with strong magnets. You don’t need other parts. It fits all calibers and gauges. Sight in your gun and notice where the crosshairs end up on the grid. Note down the placement to check zero. Magnetic bore sighters are also needed to check zero after moving your guns or dropping them.
4. Modern bore sighting
It is not done by visual inspection, it uses a laser bore sighter to aim the distant target. That is, it projects the laser beam from the arbor placed into the muzzle. Also, in this method, you don’t want to remove the bolt that allows more movement in the gun. Some laser bore sighters are sized for a specific cartridge case and you just have to insert them into the chamber of your gun for the action.
When using a laser bore sighter you need a reflective target to reflect the laser beam. And this target should be placed at a certain distance and hold your gun steady to center the crosshairs of the scope at the point of the laser.
Why should you use a bore sighter?
Boresights will save you both time and money. It is mainly used to increase the zeroing speed. By aligning the sight of optical firearms with the barrel’s position, you can zero in much faster.
Therefore, it reduces the number of rounds that you need to fire for zeroing the sights or optic properly. So you can aim and hit the target accurately without wasting even single ammo. This takes very little time to adjust and is used in shooting practice.
Also, you can use the bore sights to practice trigger control while dry-firing. You can put your shots on paper from home before you go hunting.
Types of Bore sighters
Bore sights either use a physical reticle or a laser to show approximately where the round would hit. They are designed either to chamber like a real cartridge or to fit inside the muzzle. Both types have a flat trajectory and should be used at a particular distance to achieve good results. Let’s have a look at those types;
Muzzle-mounted laser bore sighter
Most of the laser bore sights are designed to fit directly at the muzzle end of your weapon. To install the boresight, a short probe is inserted into the barrel and an adapter to secure it in place.
So each laser bore sight kit comes with more adapters to fit different sized barrels. At the muzzle, the widened body creates a snug fit. As a result, the boresight projects a straight laser beam out from the barrel.
The main advantage of muzzle-mounted laser bore sights are, it is compatible with most firearm calibers.
Chambered laser bore sighter
Chambered bore sights are shaped like an actual cartridge that sits perfectly into the barrel. So that it is easy for you to direct the laser beam to your target. It is powered by small replaceable batteries that are commonly used in small devices.
This style is compact, affordable, and is preferred by most shooters. These are generally colored bright with brass to differentiate them from real rounds.
The downside is, this type of bore sighter cannot be used in firearms of different calibers. If you have small guns or only one firearm, then it is worth it for you.
Muzzle-mounted optical bore sights
Optical bore sights are different from the above two laser bore sights. This system does not use a laser and batteries to function. They are mounted to the muzzle but use a lens with a reticle to indicate the position of your optic.
This type of optical boresight kit comes with a lens (with a crosshair reticle) to line up the reticle on your optic. The boresight set includes adapters to fit with an array of barrel diameters and calibers. They basically do not require batteries but are costlier than the laser boresighter.
Factors to consider before investing in Boresights
Boresights are important to make an accurate shot without wasting your ammo. There are a vast number of models available in the market but to make the right choice you’ve to consider some key aspects like material, usage, laser type, etc. So, it is better to read the following guide before you invest your money.
A boresight is a modular gadget added to the firearm. So it is obvious to check the durability and build quality. Aluminum alloy is the core material used in most boresights. It is lightweight but ensures high durability. Brass and bronze are also good choices that provide high durability and better balance to the firearms.
Bore sighters are of two different types; a Muzzle type and a cartridge system. It is explained in the above section, just check it out. From both types, decide which is needed for you and go for it. Our recommendation is cartridge type which is more accurate and easier than the other one.
If you want a high-precision laser beam for better sight, then you should choose a Class IIIA sensor. The best class will deliver the best output. You should also check the distance feature based on your preference. Also, choosing an active beam laser can help you with better sighting during the day.
Laser bore sighters will be accurate when used properly. It provides excellent performance for targets at 100 yards distance or more. Look for a bore sighter that is easy to mount, easy to use, and provides better flexibility for different calibers. It should also last for longer periods.
Universal sights are the best go-to options. But, some premium laser bore sighting devices can help improve your shooting experience with fewer parallax issues.
Versatility (Multiple calibers vs Single caliber)
The bore sighter you choose should handle both single and multi-caliber weapons. As the speed of firing varies, the adjustment or zeroing will also vary. As a result, the target locking must be perfect. Since it is not possible to purchase separate models for each gun, your choice must be compatible with all types of guns.
Fitting is an important aspect with bore sighters, as different types of scopes are involved in sighting. A lightweight and easily mounted bore sighter will allow you to control zeroing perfectly.
Nowadays, there are so many options available in the market. So you can find a perfect fit bore sighter for your gun. A better fitting will increase your aiming output. Besides, the DIY laser bore sights can also be used to fit the firearm properly.
If you want to get the best laser bore sighter, then you have to spend a few dollars additionally. Higher the price, higher is the quality. Usually, the price tag of bore sighters ranges from 13 to 260 USD. So, set your budget first and then go for the selection.
- Don’t force the boresight while inserting it into the chamber. Place it slowly.
- Lubricate it seldom if needed
- Adjust the sighter position with one or two hairs above the centerline based on your accuracy.
- Use a bright laser beam that is powered by batteries
- Mount the scope properly for a perfect setting
- Once the setup is checked for gun balance and scope alignment.
- Use a software program to check and customize the settings.
- Don’t let the Laser beam hit the human eye as it can damage the eye. Wear glasses if needed.
Most people think that laser bore sights are only for rifles, but that’s not true. No matter what type of gun you have, whether a single caliber, pistol, handgun, or a new rifle, boresights will provide excellent performance.
