Buying Guide for the Best Magnetic Boresighters

Choosing the right magnetic boresighter can significantly improve your shooting accuracy and save you time and ammunition. A boresighter helps you align your firearm's sights or scope with the barrel, ensuring that your shots are on target from the start. When selecting a magnetic boresighter, it's important to consider several key specifications to ensure you get the best fit for your needs. Here are the main specs to look at and how to navigate them.
CompatibilityCompatibility refers to the range of firearms that the boresighter can be used with. This is important because you want a boresighter that fits your specific firearm or multiple firearms if you own more than one. Some boresighters are designed for specific calibers, while others are more versatile and can be used with a variety of calibers. To pick the right one, check the specifications of the boresighter to ensure it matches the calibers of your firearms. If you have multiple firearms, a versatile model that covers a wide range of calibers might be more convenient.
Magnetic StrengthMagnetic strength determines how securely the boresighter attaches to the muzzle of your firearm. This is crucial for maintaining accuracy during the sighting process. Stronger magnets provide a more stable attachment, reducing the risk of movement that could affect alignment. Magnetic strength can vary, with some boresighters offering adjustable magnetic force. For most users, a boresighter with a strong, stable magnet will be sufficient. If you plan to use the boresighter in various conditions or with different firearms, consider one with adjustable magnetic strength for added flexibility.
Laser TypeThe laser type refers to the color and visibility of the laser beam emitted by the boresighter. This is important because a more visible laser makes it easier to align your sights or scope accurately. Common laser colors are red and green, with green lasers generally being more visible, especially in daylight. If you often shoot in bright conditions, a green laser might be more suitable. For indoor or low-light conditions, a red laser can be sufficient. Choose the laser type based on the typical lighting conditions in which you will be using the boresighter.
Battery LifeBattery life indicates how long the boresighter can operate before needing a battery replacement. This is important for convenience and cost-effectiveness, as longer battery life means less frequent replacements. Battery life can vary significantly between models, with some offering several hours of continuous use and others lasting much longer. If you plan to use the boresighter frequently or for extended periods, look for a model with a longer battery life. For occasional use, a shorter battery life may be acceptable.
Ease of UseEase of use refers to how simple and straightforward it is to operate the boresighter. This is important because a user-friendly boresighter can save you time and frustration. Features that contribute to ease of use include clear instructions, simple attachment mechanisms, and intuitive controls. Some boresighters come with additional accessories or tools to make the process easier. If you are new to using boresighters, look for a model with positive reviews regarding ease of use. Experienced users might prioritize other features, but ease of use is always a beneficial aspect.
