A Guide to Selecting the Best Boresighters
Choosing the right boresighter can make sighting in your firearm much easier and more accurate. A boresighter helps you align your gun’s sights or scope with the barrel, saving you time and ammunition at the range. When picking a boresighter, it’s important to consider how you plan to use it, what type of firearms you own, and how much convenience or precision you need. Understanding the key features will help you select a boresighter that fits your needs and makes the sighting process smoother.
Type (Laser vs. Optical)
The type of boresighter refers to how it helps you align your sights. Laser boresighters project a visible laser beam from the barrel, showing exactly where your gun is pointed, while optical boresighters use a lens system that you look through to align your sights. Laser types are generally faster and easier to use, especially in low light, and are popular for their simplicity. Optical boresighters can be more precise and don’t require batteries, but they may take a bit more time to set up. If you want quick and easy alignment, a laser type is often best. If you prefer a more traditional, battery-free approach, consider optical.
Caliber Compatibility
Caliber compatibility means which sizes of firearms the boresighter can be used with. Some boresighters are designed for a specific caliber, while others come with adapters to fit a range of calibers. If you own multiple firearms in different calibers, a universal or multi-caliber boresighter is more versatile. If you only need to sight in one specific gun, a single-caliber model may be simpler and more precise. Always check that the boresighter matches the calibers you plan to use it with.
Ease of Use
Ease of use refers to how simple and straightforward the boresighter is to set up and operate. Some models require more steps or careful alignment, while others are almost plug-and-play. If you’re new to sighting in firearms or want a hassle-free experience, look for a boresighter with clear instructions and minimal setup. More advanced users might be comfortable with models that offer extra adjustments for fine-tuning.
Visibility and Brightness
For laser boresighters, visibility and brightness describe how easily you can see the laser dot, especially in different lighting conditions. A brighter laser is easier to see outdoors or in bright environments, while lower brightness may be fine for indoor use. If you plan to use your boresighter in various settings, choose one with a strong, visible laser. If you’ll only use it indoors, brightness is less critical.
Durability and Build Quality
Durability and build quality refer to how well the boresighter is made and how long it will last. A sturdy, well-built boresighter can handle regular use and occasional bumps without losing accuracy. If you expect to use your boresighter often or in the field, look for models made from metal or high-quality materials. For occasional use at home, a lighter or plastic model may be sufficient.
Power Source (for Laser Models)
Laser boresighters require a power source, usually batteries. The type and availability of batteries, as well as battery life, can affect convenience. If you want a boresighter that’s always ready to go, look for one with common, easy-to-replace batteries and good battery life. If you don’t want to worry about batteries, an optical boresighter might be a better choice.
