Wheeler Professional Laser Bore Sight
  • Fits: All caliber rifles and handguns
  • Battery: 1 x CR123A Battery
  • Weight: 15.2 oz

Most laser bore sights on the market tend to be seen as toys rather than a professional weapon calibration device. This is not a problem with this Wheeler Professional laser bore sight because everything about it screens professionalism.

This bore sight uses a laser that will allow you to quickly and easily calibrate the crosshair of your rifle or handgun to your bore in a matter of seconds. It is also compatible with most handguns and caliber rifles which makes it quite flexible.

And since this unit is magnetized, it will have no problem mounting on the muzzle of your rifle or handgun. It also has a tight fit on your weapon so it will not fall over during the various adjustments that you will normally make to your weapon while using this accessory.

But what we like the most about this top-rated bore sight is that it uses a green laser rather than the traditional red color. It is significantly more visible even during broad daylight than competing models.


  • Green laser. More visible even during daylight
  • Excellent build construction from machined aluminum. Durable and long-lasting
  • Comes with a professional carryback for storage


  • The price. It is expensive

3. Bushnell 743333  Traditional Bore Sight Compatible with Most Weapons

Bushnell 743333 Bore Sight with Case & Arbors
  • Fits: All calibers from 0.22 to 0.45
  • Battery: N/A
  • Weight: 16 oz

This Bushnell bore sight has been built with fully expandable arbors that make it compatible with almost all calibers ranging from 0.22 up to 0.45. This should technically make it compatible with almost all shooting range weapons as well as hunting rifles.

Moreover, this model comes with a professional deluxe carry bag that will allow you to carry your bore sight everywhere with ease. The build construction is superb, and this model is clearly built to last a long time.

Of course, you also get a great sighting reticle with this purchase that will allow you to a very easily calibrate your crosshair and deliver an accurate and perfect shot. The only caveat is that this is a traditional bore sight and we recommend it mostly for skilled shooters who have experience.

However, based on its build construction and versatility, this model by Bushnell is definitely one of the best bore sights for the money.


  • Excellent build construction. Durable and long-lasting
  • Comes with a professional kit
  • Flexible. Fits almost all weapons from 0.22 to 0.45

SightMark SM39001 Laser Bore Sight
  • Fits: All 0.223 calibers, an AR-15 rifle
  • Battery: 3 x AG3 or 2 x AG5 Batteries
  • Weight: 3.2 oz

This SiteMark unit is almost the same as the 9 mm model we have just covered in our review. However, this one is not limited to smalltime weapons and compatible with high-caliber 0.223 weapons like an AR-15 rifle.

It has a sturdy brass construction which means that it is very durable and long-lasting. It will not corrode over time or get damaged even when used as a heavy-duty bore sight for professional use.

In order to allow you to calibrate your crosshair to the bore sight, it uses a red laser. A major caveat we have is that this laser is not very visible during broad daylight. However, it is still noticeable enough for proper alignment and offers an accuracy of 2 inches at 100 yards which are above average.

But despite all this, this SightMark model still remains the best bore sight for AR 15 because it is one of the few bore sights that has been designed specifically to align high-powered weapons.


  • Designed specifically for high-powered weapons like a AR 15 rifle
  • Excellent build construction from brass. Durable and long-lasting
  • Good dot size accuracy of 2 inches at 100 yards


  • The red laser is difficult to spot in broad daylight
  • Fairly weak battery life of 1 hour

Sightmark SM39024 Universal Bore Sight
  • Fits: All caliber rifles and pistols
  • Battery: 3 x AAA Batteries
  • Weight: 0.8 oz

Arbor type bore sights are generally a pain to work with because there are various adjustments and adapters that you need to use when installing it on your weapon. This is not a problem with this model because it is universal and works with all caliber rifles and pistols. It does not use an arbor system.

Simply place this unit in the barrel of your weapon, and it will magnetically attach to it. You can then easily sight any scope with great accuracy, and you will not have to fire one single round to do so.

Moreover, if you have never installed this type of bore sight before, then it comes with a detailed manual that will show you exactly how. The class III laser it uses is 5 mW or less which is compliant with most laws.

Based on a price to performance ratio, and considering that this model is universal, we rank it as one of the best lasers bore sight on the market.

  • Universal bore sight. Fits are caliber rifles and pistols
  • Lightweight at 0.8 oz.

In fact, it comes as a universal kit that has an adapter set that will make it fit any 0.22 to 0.50 caliber weapons, which includes rifles as well as pistols.

How to Buy the Best Bore Sights

How to Buy the Best Bore Sight

1. Types of Bore Sight

There are basically 2 types of bore sight on the market. The traditional bore sight and the laser bore sight. But what is the difference between the 2 in which one do you need?

Traditional: Also known as the optical bore sight, the traditional bore sight is used to manually sight the bore of the gun to your target and then adjust the scope to match the sighting. It is quite difficult to get right the first time, and you do need some experience to sight with the traditional bore sight.

Laser: It is significantly easier to sight with the laser bore sight because, as its name suggests, it is assisted by a laser. This will allow you to align the bore of the gun much quicker to your sighting scope.

The laser bore sight is a newer invention and is quickly replacing the traditional bore sight mostly because of its ease-of-use and superior accuracy.

In any case, the laser sight is definitely the best bore sight that you can buy if you want ease-of-use.

2. Performance

The performance in a bore sight is mostly related to its flexibility and versatility. If the bore sight is able to fit a wider range of weapons, then it can be considered to be higher “performance.”

For this reason, you need to ensure that the bore sight is compatible with your weapon because this will directly translate into performance right out of the box.

3. Battery

Since most top-rated bore sights use a laser to sight, they need a power source. This power source is usually a small battery inside the bore sight.

Ensure that your bore sight comes with a feature that warns you every time the battery is getting low.

In addition, your bore sight needs to be efficient and provide you with a long battery life.

4. Versatility

You probably own a few guns. Therefore, your bore sight must be compatible with not only one weapon but multiple weapons.

This versatility is very important especially if you plan to buy only one bore sight for all your weapons.

Moreover, make sure that the manufacturer provides you with “adapters” that will allow it to fit a wide range of weapons.

It does so by changing the diameter of the bore sight in order to produce a tight fit in the barrel of your weapon.

5. Durability

You don’t want your broadside to break after the first use. So, ensure that it is made from a durable material like metal.

This way you are guaranteed that your bore sight will be long-lasting as well as provide you with heavy-duty use over time.

6. Laser Color

You may have noticed that the bore sight comes in either red or green colors. Those are the 2 most popular colors that are clearly visible in low light conditions.

However, during the daytime, a green laser will always be more visible than a red laser.

Therefore, you need to choose the color of your laser based on the brightness of your surroundings.

7. Laser Power

In addition to the laser color, you need to also choose the laser power.

Most states and countries allow you to use a class III laser that is no more than 5 mW in power.

Luckily, most laser bore sights have a power less than 5 mW to comply with those laws.


It does not matter if you are a bad shot. With the bore sight, your aim will improve significantly because it is just so easy to use.

Indeed, the bore sight will shine a powerful laser on your target so you will be able to aim your weapon more accurately and prevent you from wasting precious rounds.

Lastly, if you have read our bore sight review above and still not decided on a model yet, then don’t worry. Read it again and go purchase a bore sight that suits your need and weapon type!
