Bushnell Golf Laser Boresighter

It is compatible with a wide range of firearms, specifically those chambered from .22 to .50 caliber. As long as your firearm falls within that range, the included set of arbors will allow you to secure the laser in the barrel.

No, the kit comes with the necessary batteries included. It runs on three LR44 batteries, which are standard and easy to replace when needed.

By getting your sights or optics aligned on paper before you head to the range, you can significantly reduce the number of shots required to zero in your firearm. While it won't replace the final live-fire adjustments, it gets you close enough that you'll likely only need a few rounds to confirm your zero.

Not at all. The process is straightforward: select the correct arbor for your caliber, insert the laser into the barrel, and adjust your optic until the reticle aligns with the laser dot. It is designed to be intuitive for both gunsmiths and casual shooters.

This tool is excellent for getting your scope on paper at shorter distances, which is the essential first step for any long-range setup. However, for extreme long-range precision, you should always perform a final live-fire zeroing process to account for ballistics and environmental factors.
