Overview
Built for hunters and shooters who want a faster, more visible way to align optics, this laser boresighting system uses a green beam designed for daytime visibility. It is sized to fit .22 to .50 caliber firearms, 20-ga./12-ga. shotguns, and muzzleloaders, with magnets that center the laser securely in the muzzle. Because no metal contacts the rifling and no optional arbors are needed, setup stays straightforward while helping reduce unnecessary handling at the range or before a hunt. It also offers up to 10 hours of continuous run time, making it a practical tool for extended sight-in sessions.

Considerations & Trade-offs
- Designed for muzzle-based boresighting, so it is not a universal fit for every firearm platform.
- The green laser’s higher visibility is aimed at daytime use, but actual visibility will still depend on lighting conditions.
- Continuous runtime is listed at up to 10 hours, so extended range sessions may require planning around battery life.
- Compatibility is broad within the stated calibers and gauges, but it does not cover firearms outside the listed .22 to .50 cal., 20-ga./12-ga., and muzzleloader range.
