10 Best Laser Boresighters 2025 in the United States

The CVLIFE Professional Laser Bore Sight Kit features a clear red Class IIIA laser which is effective for distances ranging from 15 to 100 yards. It's equipped with 32 adapters, making it highly versatile for calibers from 0.17 to 12GA. This wide range of compatibility is one of its standout strengths, allowing it to be used with virtually any firearm within this range. The clear instruction and numbered adapters ensure ease of use, letting users quickly find the right fit for their weapon.

Additionally, the high precision of the laser helps achieve consistent accuracy, which is crucial for zeroing scopes and improving shooting accuracy over time. The inclusion of an arbor accessory enhances stability for larger calibers, ensuring the bore sight fits securely at the muzzle. The construction quality is robust, made from durable aluminum, which promises a long service life and reliability during use. The battery life is impressive, up to 40 hours with the included two high-capacity batteries, reducing the need for frequent replacements and providing dependable support during extended shooting sessions.

However, there are a few drawbacks. The laser's visibility is limited in bright daylight conditions, which could affect its performance outdoors. Additionally, while the product is highly versatile, users who primarily use a single caliber might not need all 32 adapters, potentially making this kit more than they require. Lastly, it doesn't support night vision, which could be a limitation for users needing a bore sight for low-light conditions. This kit is best suited for hunting enthusiasts and shooters with diverse firearm collections seeking a reliable and accurate bore sight solution.

The EZshoot Bore Sight Laser Kit uses a bright green laser, which is generally easier to see in various lighting conditions compared to red lasers, helping with clearer aiming even when visibility is low. It supports a wide range of calibers from .17 to 12 gauge, thanks to its 16 included adapters and an arbor for stability, making it versatile for many rifles and handguns. The laser itself is compact, lightweight (0.37 pounds), and housed in a sturdy metal body, which should hold up well during regular use.

Battery life is improved by the upgraded CR2 batteries, and the large, sensitive button makes operating the laser straightforward—just a simple press turns it on or off. This ease of use is great for both beginners and experienced shooters. Accuracy is generally reliable given the firm fit with the adapters and solid construction, although, like all laser bore sighters, the final zeroing on the firearm will still require live fire adjustments. It mounts via a Picatinny rail, which is common but may not be compatible with every firearm without an adapter.

The product does not have night vision capability, which is typical for this category and usually not necessary. This makes it a practical choice for users looking for a durable, easy-to-use laser bore sighter with a broad caliber range and visible green laser, especially suited for hunters and target shooters wanting a quick and clear way to align their sights.

The Feyachi Bore Sight 9mm is a compact and precise laser boresighter designed specifically for 9mm handguns. It uses a Class IIIA red laser, which is bright enough for quick sighting but won’t overwhelm your eyes. The device fits directly into a 9mm chamber, making it easy to align your sights or scope without firing live rounds. Its sturdy brass construction feels durable and lightweight, which is great if you want a reliable tool that won’t add bulk to your gear.

Battery life is decent with three sets of batteries included, each lasting about an hour. This means you get plenty of usage time before needing replacements, though it’s important to remove batteries after use to avoid drain. The boresighter’s size is small, making it simple to insert and remove, which helps with quick setup during sighting sessions.

Accuracy is where it shines—the laser offers a fast, clear red dot that helps save time and ammunition when zeroing your firearm. However, it lacks night vision capability, so it’s best for use in normal lighting conditions. The included Picatinny mount ensures compatibility with many handgun types, although it’s mainly tailored to 9mm calibers, so other sizes won’t work without a different model. Customer feedback indicates a positive experience, highlighting its effectiveness and ease of use, while some users might prefer longer battery life or additional features like night vision. This boresighter is a solid choice if you need a straightforward, reliable tool to get your 9mm handgun sights aligned quickly and without hassle.
