  • What is a Laser Bore Sight and Why Do You Need It?



    Any time you install an optics on your rifle or other firearms, there is a chance that you might have to fix the zero. What that means is that the point where you are targeting using the scope is not the same as where the muzzle of your gun is pointing. It can even happen on its own if you keep the gun unchecked for a while.

    Sighting the weapon is often a painful process. You need to get a target and shoot bullets while trying to align the cope and muzzle. And bullets are not exactly cheap. Most people cannot afford to keep wasting bullets while calibrating their optics to the highest levels of precision.

    That is where a laser bore sight comes in. It is essentially a contraption that goes on the muzzle of your weapon and helps you align the bore or center by mimicking a strong laser at the target mimicking the trajectory of the bullet. When you look through your scope, you can easily see where the bullet will land and can align the crosshair in the optics to match that point.

    The best part about bore sighting is that even a beginner can do it without any troubles. All you need is an unloaded gun with the unaligned scope, a stable gun rest, and your laser bore sighting tool. It makes the entire process of calibrating the zero easy, economical, and straightforward.

    The major advantages of bore sighting are given below:

    • Laser bore sighting is highly precise. Using this tool, you can zero your rifle at an accuracy level that you cannot match simply using your eyes. Although experience shooter can get quite close to proper calibration at 100 yards, a laser bore sight will give you better precision.
    • You also do not need to keep looking through the barrel of your rifle. Since the laser is emitted from the muzzle of the rifle, all you have to do is check through the install scope and you can calibrate from there. When you match the reticle of the scope with the laser from the bore sight, you are done with your alignment.
    • Another major advantage of using a laser bore sight is they tend to be quite versatile. Typically, a single device can work with a lot of different weapons eliminating the need to buy multiple bore sighting tools. You can use one device across a lot of different weapons as long as it is compatible.
  • Laser bore sighting is an efficient method of sighting your rifle. It ensures that you will have to spend minimal time fiddling around with your scope moving from the scope to the barrel to check for inconsistencies. A lot of frustration that people face while sighting can easily be eliminated by using a laser bore sight
  • The entire process is quite easy on your wallet. A laser bore sight can be extremely expensive, but you usually do not need to spend too much if you want good accuracy. Besides, you will be saving a lot of money in the long run since you will not have to waste bullets while sighting your weapon.
  • Bore sighting is extremely easy. Even a beginner with minimal experience in sighting a weapon can get through this process in a decent amount of time. For a beginner, sighting can be quite difficult in most cases. With a bore sight, the task is quite simple, and there is not any steep learning curve involved in it.

  • Things to Consider when Choosing the Best Laser Bore sighter



    With the list of products out of the way, we can focus our attention to some of the best features that you should look for when buying one for yourself. A bore sight despite its simplicity, comes with many smaller aspects that you need to consider if you want a satisfactory result from your investment.

    With that said, here are a list of things that you should look for when buying the best laser bore sighter.

    • Bore Sighter Design

    The first thing that you want to consider when buying your product is the overall design and how you will mount it. There are three ways a bore sighter can be mounted, and the preferred design tends to vary from one person to another. What works for someone might not be the best choice for you.

    For this reason, we will give you a brief overview of what each of these designs is, and you can decide for yourself which one suits your requirement.

  • Magnet-mounted bore sights: Magnet-mounted bore sights feature a highly convenient design, and you can mount it easily. As the name implies, it comes with magnets that attach to the muzzle of your gun from where you can simply turn it on. Some people prefer it solely for the comfort factor.
  • Arbor bore sights: arbor bore sights come with a similar design to that of magnet-mounted units and can be equally as convenient. However, they are quite sensitive and should only be used by experts with a steady hand.
  • In-barrel bore sights: In-barrel bore sights are simple and straightforward tools that come with a longer end that goes inside the barrel of your gun. The best thing about this design is that it offers a high level of precision. However, you need to ensure that the tool is compatible with your specific weapon.
    • The Quality of Laser

    For any laser bore sight, the most important component is the laser. If the laser itself is not up to the quality, the bore sight is of no use at all. So when settling on a product, always make sure the laser quality is decent. We have highlighted which elements you need to check in the laser so that you can get a better understanding.

    Laser Class

    The easiest way to understand the quality of the laser is to look at its class. There are different classes of lasers, and it means the overall balance of light intensity, brightness, and other elements of the unit. Typically, most lasers in a bore sight are of class III.

    You can also find a higher class of laser in some expensive bore sights. But Class III is typically a good deal. It is safe for your vision, whereas higher class lasers can damage eyesight. Regardless of its class, make sure the laser never points to someone’s eyes as it might cause long term damage.

    Laser Color

    The color of the laser plays a crucial part in its visibility. Typically, there are two colors available when choosing a bore sight, red and green. Red lasers are usually less expensive models. But they can be difficult to detect in bright outdoor environments.

    On the other hand, green lasers can be easily seen even under sunlight. If you are planning to mostly use the bore sight indoors, then you can get away with a red laser. However, if you want to take it outdoors, then investing in a green laser might be better for you.

    Laser Intensity

    The intensity of the laser is one other thing you need to check. This contributes directly to the brightness of the laser, and with greater brightness, you will have better visibility. It is usually measured in nm, and sometimes you can find it clearly specified in the product specs.

    Human eyes are more sensitive to a range of 500 to 550 nm. The closer the intensity range of the laser is to this value, the better the brightness. If you go with a unit that has an intensity within 600 to 700 nm, you should be fine in most cases. However, with a better intensity range, the price also gets higher.

    • Weapon Compatibility

    What good is a laser bore sight if it is not compatible with your weapon? So before you settle on a specific product, look at the manufacturer’s recommendation for compatible weapons. The design and size of the bore sight need to match your weapon if you want to use them together.

    You can find both weapon specific and universally compatible units in the market. However, weapon specific models typically give you a better performance as it is designed to work perfectly with that weapon. On the other hand, universal models give you the option to use any weapons which directly translate to its versatility.

    • Build Quality

    Would you ever invest in something that breaks down after a couple of uses? Of course not. Before you start spending your cash, it is always essential to look at the overall build quality of the unit. TO understand the build quality of a bore sight, consider its material of construction.

    If you are sticking with a reputed brand, you have a better chance of ending up with a durable product. But they cost more, and not everyone has the budget for it. In that case, consider the structural quality of the unit critically, look for any flex in the product, and try to determine whether it can survive even after taking a beating.

    • Battery Life

    A laser bore sighter depends on battery for power, and if the unit you buy cannot utilize battery power efficiently, you will not be happy with it. If you need to keep changing batteries every time you sight a weapon, before long, the cost of additional batteries will start putting a dent in your wallet.

    You should invest in a unit that offers at least a few hours of consistent battery uptime. A long as you can use your bore sighter at a few sighting sessions, you should be okay with it. With good battery utilization, you will be able to get a better overall experience with the unit.

    • Price

    Price is, of course, a deciding factor in any investment. Regardless of what you are buying, unless you have an unlimited budget, you should always look to get the most value. That means, not to go with the cheapest unit on your budget, but to go for something that offers you exactly what you need with a little more on the side.

    Besides, without a preset spending limit, you will easily get overwhelmed, looking at all the different units available at different price points. But a fixed budget allows you to filter your requirements and only look at the units at a certain price range.

    Frequently Asked Questions



    How do I use a laser bore sight?

    As we have already said, using a laser bore sight is extremely easy. Even a beginner can do it without any supervision with minimal hassle. After getting your laser bore sight, the first thing to do is obviously to read the instruction manual. It should contain all the basic information you need to get started.

    After that, check the battery compartment of the unit, and insert the battery. Try turning it on and see if it works as advertised. If everything is okay, turn it off, and you are ready to get started. You also need a gun bipod or some other type of holder to keep your gun steady while you adjust the sight.

    • The first step is to unload your gun and position it on the stand. You also need to position a target at a certain distance, depending on how far you are willing to adjust. If you do not have a proper target, you can also use a sack of sand.
    • Then install the bore sighter on the muzzle and aim through the sight. Through the scope, zero the reticle on the laser that you see on the target.
    • Now you can remove the bore sight and load your gun. Through the scope, aim at the center of the target and fire a shot.
    • Reinstall the bore sight again after unloading your gun and look through the scope. Your reticle needs to be positioned on the entry point of the bullet while the laser still points at the target’s center.
    • Remove the sighter and load up your gun again. Through the reticle aim, at the target and fire a shot. It should now pass through the entry hole that you previously made.

    That’s it; you are done with your calibration. If the target still misses, then you need to repeat the calibration steps until it gets perfected.

    Are there any safety tips I need to worry about when using the best bore sight?

    Not really. As long as you use your common sense, you should not have any trouble using a bore sight regardless of its design. Although you should maintain all the gun safety rules in general anytime, you are working with a firearm. Most importantly, never let anyone come between you and your target when shooting.

    Before inserting the bore sighter, make sure the gun chamber is empty. It should really go without saying since the bore sighter essentially goes on the muzzle blocking the bullet’s exit point in the weapon. If you fire with a bore sight equipped, not only will the sight get destroyed, but so will your weapon.

    Furthermore, it makes sure the battery is fresh. Emitting a laser can be quite taxing on any batteries. If you are going with a budget-friendly model, you might not get the best battery life out of the unit. As a result, you should always keep replacement batteries using a laser bore sight just to be safe.

    Are laser bore sights accurate?

    Laser bore sights are as accurate as it can get when you are sighting your scope. It offers extreme precision and has a smaller error margin compared to other sighting tools. At the very least, it is far more accurate than zeroing your rifle using only your eyes.

    However, no sighting tools are 100 percent accurate. There is always an offset that gets amplified when you are using different caliber ammo.

    Final Thoughts

    A laser bore sight tool is a must-have tool for people who love their sights. With it, you will be able to calibrate each sight to ensure peak accuracy.
