The 10 Best Laser Bore Sights

Zeroing in a new sight can be a frustrating experience. Unless it’s already reasonably accurate out of the box – which would only happen by coincidence – you need to start with the target just a few yards away in order to even hit the 10-ring, never mind the bullseye. You’ll then need to keep moving the target back, fine-tuning your scope as you go until you’re slagging dimes at a hundred yards or more.

One way to make the process far less painful is to use a boresight laser, which is why we’ve put together a list of the best laser bore sights. In making our selections, we’ve tried to find at least one sight for every common caliber, and several that will fit the most popular calibers, like .223 Remington and 9mm. We’ve also tried to cover a broad price range, so there will be something here that fits every budget.

Best Laser Bore Sights

1. Wheeler Professional

The Wheeler Professional green laser is clearly visible at 100 yards, even in broad daylight.

Key Features

• Fits almost any rifle, shotgun, or handgun
• Available with a green or red class III laser
• Magnetic barrel mount
• Takes one 123A battery (included)

The Wheeler Professional Laser Bore Sighter is available with a red or a green laser. They’re both a bit pricey, and the green is pricier, but we recommend going with the green version regardless. It’s visible at much longer ranges, up to 100 yards.

This sight has a magnetic mount, which sticks to the end of your barrel. Without the need for a barrel rod, you won’t have to worry about scratching the chrome lining. It also fits on virtually any barrel, making it one of the few bore sights that can be used to zero in a pistol.

It’s not quite as accurate as some other models since you need to center it manually. But it will still get you close enough to zero your scope with two shots.

Pros

• Long-range visibility
• Won’t scratch the inside of your barrel
• Rugged design
• Includes a molded plastic storage case

Cons

• Not self-centering
• Pricey

The magnetic barrel mounting system on this bore sight gets you on target without the need for a rod that may scratch the inside of your barrel.

2. SiteLite

The SiteLite has a foam padded barrel rod, which protects your barrel’s chrome lining.

Key Features

• Fits .22 to .50 caliber rifles, and 12 to 20 gauge shotguns
• Red class III laser
• Foam padded barrel rod
• Takes 2 custom rechargeable batteries (included)

The SiteLite is a red laser bore sight that’s designed to fit almost any rifle or shotgun, from .22 caliber to 12 gauge. It features a foam-padded barrel rod, with multiple pads that are sized for most common calibers. This simultaneously keeps it centered, and protects your barrel from any scratching.

It includes SiteLite’s smartphone app, which can quickly generate a printable target for any caliber, load, and range. With a custom target, you’ll be able to compensate for ballistic drop much more easily than you will with a standard target from Wal Mart or your local gun shop.

It will fit in long-barreled pistols, but not compact pistols. The 3 ¾-inch rod is too long for most of those models.

Pros

• Won’t scratch the inside of your barrel
• Includes a smartphone app
• Includes multiple barrel adapters
• Lifetime manufacturer’s warranty

Cons

• Too long for compact pistols
• Pricey

This bore sight is used by the US Navy and Marine Corps Aviation Unit weapons.

3. Okeba

The Okeba comes with 4 adjustable rubber bore adapters, which can fit almost any caliber.

Key Features

• Fits .22 to .50 caliber rifles and pistols
• Red class III laser
• Aluminum barrel rod with a rubber bore adapter
• Takes 2 AG13 batteries (included)

The Okeba Laser Boresighter is a barrel-mounted laser bore sight that stays in place with an adjustable rubber bore adapter. It ships with 4 of these, sized to fit from .22 to .50 calibers. To fit any caliber, simply use the largest bore adapter that will fit, and screw the sight down until the rubber is flush with the barrel.

Unfortunately, the adapters are very short and can tilt when you’re screwing them in, throwing off the accuracy of the laser. Be careful to make sure it’s as straight as possible, or you’re liable to be off-target. That said, this laser bore sight is very affordable, and the red laser is very bright, visible at 100 yards or more even in daylight.

Pros

• Long-range visibility
• Includes 4 adjustable rubber bore adapters
• Affordable

Cons

• Too long for subcompact pistols
• Not very accurate

This laser bore sight is affordable enough for just about any budget.

4. SiteLite Ultra

The SiteLite Ultra includes a scope leveler for getting your crosshairs as close as possible to the bullseye before sighting.

Key Features

• Fits .22 to .50 caliber rifles, and 12 to 20 gauge shotguns
• Green class III laser
• Foam padded barrel rod with magnetic core
• Takes 2 custom rechargeable batteries (included)
• Includes a scope leveler
• Magnetized rod for added stability

The SiteLite features a magnetic barrel rod and flare, which keeps it centered even if you accidentally insert it at the wrong angle. The barrel rod is foam padded, and the kit includes multiple pads to protect most common caliber barrels.

Like SiteLite’s basic Mag Laser Boresighter, the ultra includes a smartphone app for creating custom sighting targets. It also includes a scope leveler, for adjusting your scope as close as possible before you start zeroing it in. All of this will cost you a decent amount of coin, but you’re not going to find another sight that’s this accurate or has this many bells and whistles.

Pros

• Long-range visibility
• Exceptionally accurate
• Won’t scratch the inside of your barrel
• Includes a smartphone app
• Includes multiple barrel adapters
• Lifetime manufacturer’s warranty

Cons

• Too long for compact pistols
• Expensive

This laser bore sight is the most accurate one on our list.

5. LaserLyte

The LaserLyte Kit’s barrel rod is only 3 inches long, making it suitable for most pistols.

Key Features

• Fits .22 to .50 caliber rifles, .12-.20 gauge shotguns, and most pistols
• Red class III laser
• Aluminum barrel rod with plastic bore adapters
• Takes 3 BAT-393 batteries (included)

The LaserLyte Universal Laser Bore Sight Kit is a barebones, easy-to-use bore sight that fits most rifles, shotguns, and pistols. The aluminum barrel rod has a flared design. Simply press it into your barrel until it fits snugly, and zero in your scope. For shotguns, you can use the plastic bore adapters to get a snug fit.

The downside of this barebones design is that the aluminum rod can potentially scratch the chrome lining on your barrel. The laser is also fairly weak, only useful out to about 25 yards in daylight. The batteries are also an unusual size, making them difficult to find in local stores. That said, this is an affordable kit, it takes just seconds to set up, and it’s short enough to accommodate pistol barrels 3 inches and longer.

Pros

• Suitable for most pistols
• Easy to use
• Affordable

Cons

• Hard to replace batteries
• Limited range
• Can potentially scratch your barrel

This bore sight takes only seconds to set up and comes at a reasonable price.

6. Sightmark

The Sightmark fits in your rifle’s chamber, so there’s no chance of it scratching your barrel.

Key Features

• Fits .308 and .243 Winchester, 6.5 Creedmoor, and other .308-based chambers
• Red class III laser
• Fits in your rifle’s chamber
• Takes 2 AG5 batteries (included)

The Sightmark Boresight is a red laser bore sight that’s the same shape and size as a necked down .308 cartridge. It’s designed to fit in your rifle’s chamber, so it won’t scratch your barrel’s chrome lining. Because it’s a .308, it also fits in chambers that are based on the .308, such as .243 Winchester and 6.5 Creedmoor.

This laser bore sight is exceptionally accurate, since it fits right in your chamber, just as a live cartridge does. The laser is visible to 50 yards on a paper target, or out to 100 yards on a reflective target. Needless to say, it will get you inside the 10-ring easily anywhere in this range, allowing you to zero your sight quickly and easily.

Pros

• Long-range visibility
• Exceptional accuracy
• Won’t scratch your barrel
• Affordable

Cons

• Only fits .308 and similar chambers

This laser bore sight is ideal for zeroing in your hunting rifle.

7. MidTen

The MidTen provides a visible laser dot out to 100 yards.

Key Features

• Fits .30-06 and similar chambers
• Red class III laser
• Fits in your rifle’s chamber
• Takes 3 LR41 batteries (included)

The MidTen Red Laser Bore Sight is another laser bore sight, this time chambered in .30-06. It’s also compatible with chambers based on the .30-06, such as .25-06 Remington and .270 Winchester. Because it fits directly in your chamber, it won’t scratch your barrel lining, and it’s pinpoint accurate.

This red bore sight is visible to 100 yards, which makes it well-suited to use for hunting. The price is on the low end, comparable to just a few .30-06 cartridges.

Pros

• Long-range visibility
• Exceptional accuracy
• Won’t scratch your barrel
• Affordable

Cons

• Only fits .30-06 and similar chambers

If your hunting rifle is chambered in .30-06, this is the perfect laser bore sight for you.

8. Give Me Bore Sight

The Give Me Bore Sight comes with a 1-year manufacturer’s warranty, which tells us the manufacturer is confident in their product.

Key Features

• Fits .223 Remington and similar chambers
• Red class III laser
• Fits in your rifle’s chamber
• Takes 3 LR41 batteries (6 included)

The Give Me Bore Sight is the third cartridge-style bore sight on our list. It’s sized for .223 Remington, and will also work in 5.56×45mm NATO chambers. Like other cartridge-style bore sights, it’s extremely accurate. The laser is visible at long ranges for a red dot, as far as 100 yards under ordinary daylight conditions.

This is an ideal bore sight for your AR, but make sure to take the batteries out when it’s not in use. There’s no “off” button, so they’ll run dead quickly if left in.

Pros

• Long-range visibility
• Exceptional accuracy
• Won’t scratch your barrel
• 1-year manufacturer’s warranty
• Affordable

Cons

• No “off” button
• Only fits .223 Remington and similar chambers

This laser bore sight is perfect for sighting in your AR.

9. CTOPTIC

The CToptic is an affordable laser bore sight with a long-range red laser.

Key Features

• Fits .177 to .50 caliber rifles and handguns
• Green class III laser
• Aluminum barrel rod with rubber bore adapters
• Takes 1 CR2 battery (included)

The CToptic mounts in the barrel of your gun and is fitted with multiple rubber bore adapters to fit a variety of firearms, from .177 to .50 caliber. This makes it uniquely well suited to use in air guns since most bore sights won’t fit in that small of a caliber.

The rubber mounts allow for plenty of accuracies but can be difficult to insert. Be careful to push them straight in, or you may end up scratching your barrel lining. All in all, CTOptic is a good value for the price.

Pros

• Long-range accuracy
• Can be used on air guns
• Affordable

Cons

• Can potentially scratch your barrel

This is one of the few laser bore sights on the market that can be used to zero in an air gun scope.

10. Simmons Laser Boresight

The Simmons Laser Boresight is an affordable, barebones laser bore sight.

Key Features

• Fits .22 to .50 caliber rifles and handguns
• Red class III laser
• Aluminum barrel rod
• Takes 3 LR41 batteries (included)

The Simmons Laser Boresight is a basic aluminum bore sight with a red, class III laser. It only shows up at about 20 yards in daylight, but that’s more than enough to get your rounds inside the 10-ring before you move it out to longer range. Be careful inserting it into your gun. There’s no padding of any kind on the barrel rod, so it’s easy to scratch your barrel if you insert it casually.

It is what we’d use as a benchmark for others. It doesn’t have any extra bells and whistles. It just works, and it works well. It’s also affordable, a real bargain considering how reliable it is.

Pros

• Easy to use
• Affordable

Cons

• Can potentially scratch your barrel

This boresight is very easy to use; press it into your barrel, and you’re ready to go.

Bottom Line

In our search for the best laser bore sighter, we’ve covered a lot of ground. We’ve looked at green bore sights, which are highly visible at long distances. We’ve also looked at red bore sights, which tend to cost less in units that have comparable accuracy to their green counterparts. Ultimately, the best bore sight is going to be the one that works best for your gun and your budget.

One thing we haven’t mentioned is that a boresight is only going to be pinpoint accurate at point-blank range. Beyond that, they can’t account for the ballistic drop. So you can’t just line up your scope with your boresight at 100 or 200 yards and call it a day. Use the boresight as a benchmark, but follow up by firing live ammunition at the target to account for sighting at different ranges.
