  • Bore sighting is an essential step in zeroing a firearm, helping shooters align their sights or scope with the barrel to save time and ammo at the range. A reliable bore sighting tool can streamline this process, whether you’re sighting in a new rifle or checking your current setup. Bore sighting tools come in various types, such as laser bore sighters and collimators, with laser bore sighters being especially popular for their ease of use and versatility. These tools project a laser beam down the barrel, providing a visual reference for sight alignment. When selecting a bore sighting tool, accuracy is crucial—it should offer a consistent reference point that aligns with the firearm’s true bore axis. Durability is also important for withstanding field use. We considered factors like battery life, ease of use, and caliber compatibility to test and find the best bore sighting tools that balance accuracy, durability, and value for shooters.

    Pros

    • 50 numbered adapters for many calibers
    • Bright green laser visible up to 300 yards
    • Long 32-hour battery life

    Cons

    • Case could be more durable
    • Adapter sizes in mm, not calibers
    • Instructions could be clearer

    We tried out the MCREHOTZ bore sight kit and were impressed by its range. The 50 adapters fit guns from .17HMR to 12GA, so we could use it on all our firearms. The numbered adapters made it easy to find the right size, though we had to guess a bit since they’re marked in mm.

    The green laser was super bright. We could see it clearly even in daylight at 300 yards. This made zeroing in our scopes quick and simple. We didn’t waste time or ammo at the range.

    Battery life was great. We used it for hours over a few days and it’s still going strong. The kit comes with two CR2 batteries, which is nice. The case fits everything well, but we wish it was a bit tougher for field use.

    Pros

    • Fits many calibers
    • Bright, visible laser
    • Long battery life

    Cons

    • Some adapters may fit loosely
    • Plastic parts can break
    • Limited range

    We found the EZshoot bore sight to be a handy tool for getting our guns on paper fast. The kit comes with 16 adapters to fit calibers from .17 to 12 gauge, which let us use it on most of our firearms. The red laser was bright and easy to see, even in daylight.

    The big button was simple to use, and we liked that it came with two CR2 batteries. This gave us plenty of sighting time. The aluminum body felt sturdy, though we noticed some of the plastic adapters seemed a bit fragile.

    At the range, we got our scopes and sights close to zero quickly. This saved us time and ammo. While not perfect, it got us on paper fast. For fine-tuning, we still needed to fire some live rounds. Overall, we think this bore sight is a good value for gun owners with multiple firearms.

    Pros

    • 32 numbered adapters for many calibers
    • Long 40-hour battery life
    • Includes arbor for larger calibers

    Cons

    • Laser can be hard to see in bright daylight
    • Learning curve for first-time users

    This CVLIFE bore sight kit impressed us with its 32 numbered adapters. We found it easy to pick the right size for our guns from .17 to 12 gauge. The clear labels on each adapter meant we didn’t waste time guessing.

    When we tested the laser, it was bright and accurate. We zeroed in several scopes quickly at 50 yards. The button switch made it simple to turn on and off. At dawn and dusk, the laser showed up well. But in full sun, we had to shade the target to see it clearly.

    We liked the long battery life. With 40 hours of use, we didn’t need to change batteries often. The extra arbor was handy for our larger caliber guns. It helped the sight fit snugly in the muzzle. For the price, this kit offers good value for both new and experienced shooters.

    Pros

    • Easy to use and install
    • Fits multiple calibers
    • Long battery life

    Cons

    • No on/off switch
    • Laser can be hard to see in bright light
    • May require manual removal

    We tried out the MidTen Laser Bore Sight and found it to be a handy tool for getting our sights on target quickly. The brass construction feels sturdy, and it fit snugly in our .223 caliber rifle without any wobble. We liked that it comes with two sets of batteries, giving us plenty of use time before needing replacements.

    Using the bore sight was straightforward. We simply inserted it into the chamber and closed the action. The red laser dot was visible out to about 25 yards in indoor lighting, though we did struggle to see it clearly outdoors on a sunny day. This is a common issue with red lasers, so we weren’t too surprised.

    One quirk we noticed is that there’s no on/off switch – the laser activates as soon as you insert the batteries. It’s not a dealbreaker, but it means you’ll need to remove the batteries between uses to conserve power. Also, in some firearms, we had to gently tap or poke the bore sight to remove it after use.

    When we tried it out, we noticed the graduated grid reticle was clear and easy to read. Each mark on the grid equals 4 inches at 100 yards, which helped us make precise adjustments. The kit comes with three expandable arbors and a fixed rod for .17 caliber, covering all our bases.

    We appreciated the included carrying case, which kept all the parts organized. The boresighter felt solid in our hands, suggesting it can withstand regular use. While it took some practice to get the hang of it, we found it saved us time and ammo once we mastered the technique.

    Battery life impressed us. With two sets included, we didn’t have to worry about running out of power mid-session. The simple button switch made turning the laser on and off a breeze. While we liked the red laser, some users might prefer a green option for daytime use.

    Pros

    • Works with many gun types and calibers
    • Bright, visible laser beam
    • Stays partly outside barrel for safety

    Cons

    • Some adapters may not fit perfectly
    • Indoor use can be tricky
    • Laser alignment may need adjusting

    We tested the Pinty Laser Bore Sight on several guns in our collection. This handy tool lets us dial in sights without firing a shot. It fits rifles, shotguns, and handguns from .22 to .50 caliber.

    The laser beam is bright and easy to see. We liked that it sticks out of the muzzle a bit for safety. This design stopped us from accidentally dropping it down the barrel. The aluminum body feels solid too.

    We had some trouble with a few of the adapters. They didn’t always fit snugly in every gun. The laser wasn’t perfectly centered in some cases and needed tweaking. For the price though, it works well enough for most shooters. Just take care when using it indoors – the bright beam can be hard to see at very short ranges.

    Pros

    • Strong magnet attaches quickly to any firearm
    • Works with many types of guns and scopes
    • Easy to use with clear etched reticle

    Cons

    • Alignment can be tricky at first
    • May not work well with some crowned muzzles

    We tested the Bushnell Magnetic Boresighter on several rifles and found it to be a handy tool for getting scopes roughly zeroed before hitting the range. The powerful magnet stuck firmly to our barrels, and we liked not having to fuss with arbors or adapters.

    The etched glass reticle was clear in most lighting conditions, though we did struggle to see it clearly in bright sunlight. It took us a few tries to get the alignment just right, but once we got the hang of it, we were able to get our scopes very close to zero with just a few shots.

    We appreciated how this boresighter worked with different calibers and firearm types. It’s not perfect – the alignment process has a learning curve, and it may not suit all muzzle types. But for most shooters, we think it’s a useful tool that will save time and ammo in the long run.

    Cons

    • Instructions could be clearer

    We recently got our hands on the CVLIFE Bore Sight Laser Kit, and it’s packed with features. The 64 caliber adapters cover a wide range of guns, from .17 to 12 gauge. We found the green laser easy to see, even in bright light.

    The kit comes in a sturdy case, which is nice for keeping everything organized. We like the added arbor for .51-12GA barrels. It helps keep the sight steady when aiming. The kit includes two batteries, but we noticed they didn’t last as long as we’d hoped.

    Using the sight took some getting used to. The instructions weren’t very clear, so we had to figure things out on our own. Once we got the hang of it, we were able to sight in several guns pretty quickly. It saved us time and ammo at the range. While most adapters fit well, we did have some trouble with a few falling out of the barrel.
