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.

Buying Guide for the Best Laser Boresighters

Choosing the right laser boresighter can significantly improve your shooting accuracy and save you time and ammunition. A laser boresighter helps you align your firearm's sights or scope with the barrel, ensuring that your shots are on target. When selecting a laser boresighter, it's important to consider several key specifications to ensure you get the best fit for your needs. Understanding these specifications will help you make an informed decision and enhance your shooting experience.
Laser TypeThe laser type refers to the color and wavelength of the laser beam emitted by the boresighter. Common laser colors are red and green. Red lasers are typically more affordable and work well in low-light conditions, while green lasers are more visible in daylight and have a longer range. If you plan to use the boresighter primarily indoors or in low-light environments, a red laser may suffice. However, if you need better visibility in bright conditions, a green laser would be a better choice.
Caliber CompatibilityCaliber compatibility indicates the range of firearm calibers that the boresighter can be used with. Some boresighters are designed for specific calibers, while others come with multiple adapters to fit various calibers. It's important to choose a boresighter that matches the caliber of your firearm. If you own multiple firearms with different calibers, consider a universal boresighter that can accommodate a wide range of calibers to ensure versatility and convenience.
Battery LifeBattery life refers to how long the boresighter can operate on a single set of batteries. This is important because a longer battery life means less frequent battery changes and more consistent performance. Battery life can vary significantly between models, so consider how often you plan to use the boresighter. For occasional use, a shorter battery life may be acceptable, but for frequent use, look for a model with longer battery life to avoid interruptions.
Construction QualityConstruction quality pertains to the materials and build of the boresighter. High-quality materials, such as aircraft-grade aluminum, ensure durability and longevity. A well-constructed boresighter can withstand the rigors of regular use and maintain accuracy over time. If you plan to use the boresighter frequently or in harsh conditions, investing in a model with robust construction is advisable. For occasional use, a less rugged model may be sufficient.
Ease of UseEase of use refers to how simple and straightforward it is to operate the boresighter. Features such as easy-to-read instructions, quick setup, and user-friendly design contribute to ease of use. If you're new to using boresighters, look for a model with clear instructions and a simple setup process. Experienced users may prioritize advanced features, but overall, a boresighter that is easy to use will save time and reduce frustration.
AccuracyAccuracy is the precision with which the boresighter aligns your sights or scope with the barrel. High accuracy ensures that your shots are on target, reducing the need for further adjustments. Accuracy can be influenced by factors such as laser quality and construction. For critical applications, such as hunting or competitive shooting, prioritize a boresighter known for its high accuracy. For general use, a standard level of accuracy may be sufficient.
