The 10 Best Laser Bore Sights in 2021

1. Best Overall Laser Bore Sight: MidTen Cal 223 Rem

The high accuracy, affordability, and compatibility with popular rifles make MidTen Cal 223 Rem our best overall laser bore sight.

One of the reasons this bore sight is popular is its compatibility with .223 caliber rifles, which are a favorite for hunting enthusiasts and professionals.

This bore sight produces a visible red laser that has a sighting range of 15 to 100 yards, which is more than enough for enhanced target accuracy at your regular shooting range. With a dot size of 2 inches at 100 yards, you are guaranteed of enhanced target visibility.

Boasting of strong brass construction, this bore sight will be your reliable rifle companion for many years, and you may never need to replace it. It is also easy to insert in the rifle bore.

Even though you get 2 sets of 6 AG3 batteries to get you started with the MidTen Cal 223 Rem, their 1.5-hour life means they run out very fast.

2. Best Inexpensive Laser Bore Sight: CVLife Cal 223 Rem

CVLife Cal 223 Rem is the most affordable laser bore sight on our list, and one of the most popular among .223 Remington caliber rifle owners.

Its popularity is attributed to a perfect combination of affordability, compactness, and lightweight construction. You’ll enjoy its fast gun zeroing, which helps reduce the wastage of shells and cartridges.

The unit’s sturdy brass construction is not only a durability booster but also enhances the sight’s positioning in the rifle bore, for accurate sightings.

Also, it works great even in harsh temperatures of -10°C and 40°C. You can use the bore sight for most of the year and still count on its reliability.

A slight inconvenience with CVLife Cal 223 Rem is that it has no On/Off switch. You have to unscrew and remove batteries after every use.

3. Best Laser Bore Sight for All Firearm Calibers: Wheeler Professional Laser

The high-performance Wheeler Professional Laser implements a unique connection mechanism that allows it to fit rifles and handguns of any caliber.

It offers a strong magnet connection for easy and fast attachment to gun muzzles. The magnet is very strong, securing the unit firmly on guns for dependable and accurate performance.

You can count on the sight’s strength and durability thanks to its machined aluminum body. It is wrapped in a soft rubber overmolding to help enhance grip and handling.

As a bonus, this unit comes with a molded plastic storage case that is lined with a padded insight for an additional layer of protection.

Because the Wheeler Professional Laser is a unique and robust bore sight, it doesn’t come cheap. Its premium price will not appeal to budget buyers.

4. Best 12-Gauge Laser Bore Sight: MidTen 12GA

If you own a 12-gauge rifle, such as a semi-automatic shotgun, the MidTen 12GA laser bore sight is purpose-built for its chamber.

The reliable accessory sits perfectly in the rifle bore, and capitalizes on its strong brass build to boost stability, fast gun zeroing, and sighting.

Because this top-rated bore sight helps achieve high sighting accuracy, it effectively reduces wastage of shells and cartridges, saving you time and money.

You’ll also be pleased with the inclusion of 1 battery set containing the 3 AG13 cells required to power the accessory.

Not only does it deliver a large dot size of 2 inches at 100 yards, but will also work well in harsh temperatures as low as -10°C and highs of 40°C.

You may experience range limitations in the MidTen 12GA during daylight outdoor applications. Perhaps a green-laser version would be great for diversity.

5. Best Laser Bore Sight for Pistols: Sightmark SM39017

Pistols can also benefit greatly from laser bore sights such as the Sightmark SM39017 , which is designed for the .45 ACP handguns.

It offers a convenient and accurate sighting system for pistols, helping you achieve accurate aims without firing a single shot. For this reason, it is a popular accessory for competitive shooters, hunters, and law enforcement professionals.

Pre-calibration is one of the features that enhances the bore sight’s precision. It also offers fine adjustment for true centers, while the unit’s brass construction boosts bore stability.

In the long-run, these accuracy-boosting features will help reduce ammo and cartridge wastage, while boosting your marksmanship.

And to ensure the accessory is protected at all times, a lightweight carrying pouch has been included.

Although the Sightmark SM39017 is an excellent handgun bore sight, you will need to remove the batteries after every use, to turn it off, a process that can prove inconvenient.

6. Best Long-Range Laser Bore Sight: Laserlyte MBS-1

Sighting range is a top priority when choosing a laser bore sight, and that is where Laserlyte MBS-1 thrives.

It packs one of the brightest and most powerful legally-allowed lasers which manages a range of up to 500 yards (457.2 meters), at night. The long-distance sighting it delivers is unrivaled by other bore sights in its class.

The bore sight adopts a universal design that fits all .22 to .50 caliber rifles and requires a least 3 inches of barrel length, for maximum firearm compatibility.

Versatility is another area where Laserlyte MBS-1 excels. The bore sight is compatible with scopes, iron sights, and laser gun sights.

You’ll also enjoy using this bore sight because it offers a convenient On/Off roll switch, which is absent in most of the rival models.

Because the Laserlyte MBS-1 is a multi-component laser bore sight, it’d have been great if a carry pouch or case was included, because it is essential.

7. Great Laser Bore Sight for 9mm Chambers: MidTen 9mm

MidTen 9mm is a laser bore sight that’s been optimized to fit 9mm chambers while helping achieve rapid gun sighting and zeroing.

Because it’s built for relatively short chambers, this bore sight sits perfectly and firmly in the bore with stability being further boosted by a strong brass construction. The accessory will not require replacing for a long while.

The visible red laser’s high accuracy will reduce wastage of cartridges and shells, especially when sighting in the range of 15 to 100 yards. And getting started with the bore sight is easy because its 3 required AG3 batteries are already included.

Removing the MidTen 9mm from the barrel may prove to be a cumbersome process because there’s no ejector mechanism. You need to use a cleaning rod for this process.

8. High-Precision & Accurate Laser Bore Sight: Sightmark SM39001

Superior sighting precision and accuracy are the main highlights of the Sightmark SM39001 laser bore sight.

This .223-caliber firearm accessory has been recommended by the National Tactical Officers Association for its sighting convenience, accuracy, and cost-effectiveness, all of which help reduce shell and cartridge wastage.

The bore sight is easy to use. After chambering the unit like a regular bullet, it produces a red laser dot, which indicates the exact point your rifle is aiming.

Compatibility with .223-caliber rifles makes the bore sight a favorite for many users including competitive shooters, law enforcement, and hunters.

A lightweight carrying pouch has been included for ease of portability, and provides some protection to the laser, especially when you’re out with it in the field.

Even though the required AG3 batteries have been included with the Sightmark SM39001, they manage a limited life of 1 hour, which is shorter than that of most rival models.

9. Laser Bore Sight with A Lifetime Warranty: SiteLite SL-100

The SiteLite SL-100 laser bore sight promises to deliver superior and reliable accuracy to all your .22 to .50 caliber, plus 20 and 12-gauge shotgun rifles, thanks to its lifetime warranty offering.

Not only does it support most of the popular rifles for shooting professionals and enthusiasts, but the bore sight managers an impressive sighting range of 300 yards, which is longer than that of most rival models.

While many of the bore sights we have reviewed manage a battery life of 1.5 hours only, this one manages to squeeze out an extra 30 minutes from its 2 LR44 batteries, for a 2-hour life.

You also get a Ballistic Targeting System software program by SiteLite to help you with mastery of laser bore sighting for specific rifles and ammo.

On the downside, however, the SiteLite SL-100 is not very pocket-friendly. It may not appeal much to budget buyers.

10. Laser Bore Sight with Long Battery Life: Sightmark SM39024

The efficiency-boosting strobe mode of Sightmark SM39024 helps the laser bore sight conserver power and extend its battery life.

This bore sight capitalizes on the strobe mode’s low power consumption to extend battery life by up to 150%. You won’t have to replace the 3 AG3 batteries of this accessory after every hour or so as is the case with other models.

Efficiency is also added to the setup process, though the inclusion of magnetic attachment. Simply load the batteries as prescribed, then place the bore sight’s base onto the rifle barrel’s end. The magnet unit attaches very firmly.

For sighting accuracy, the bore sight comes already calibrated, while its brass construction and protective carry case extends the unit’s durability.

And although Sightmark SM39024 comes with a convenient power switch, it is easy to trigger it while the sight is in the carry case, so extra caution is necessary.
