CVLIFE Laser Bore Sight Kit, 32 Adapters for .17–12GA, Red Laser with Button Switch

The CVLIFE Professional Laser Bore Sight Kit helps with firearm sight zeroing and includes 32 adapters for calibers from .17 to 12GA.

• 32 numbered adapters cover .17 to 12GA calibers — choose an adapter by its clearly marked number.
• Laser centering is checked — support consistent sight alignment while saving cartridges and shells.
• Two high-capacity batteries provide up to 40 hours of use — the button switch also makes repeated zeroing sessions convenient.
• An arbor accessory fits the .551-12GA muzzle — its expanded rear end is designed to improve fit and stability.
• Red laser visibility reaches 15–100 yards (13.7–91.4 m); Class IIIA output is less than 5mW.

Zeroing a scope or red dot sight can involve using cartridges or shells to confirm alignment. This laser bore sighter is made to support that process across a broad caliber range, with numbered adapters to help distinguish the fit for each setup. Its button switch is useful when working through multiple optics.

How does the CVLIFE bore sighter support zeroing?

It uses a red laser, with the laser centering checked as part of the instrument’s accuracy process. The visible distance is 15–100 yards (13.7–91.4 m), and the laser is Class IIIA with output below 5mW. The kit is designed to help establish consistent alignment while reducing the need to use cartridges and shells for the sighting process.

• Red laser bore sighter.
• Class IIIA laser, less than 5mW.

What powers the CVLIFE bore sight kit?

Two high-capacity batteries power the unit for up to 40 hours. A button switch controls operation, making it convenient to use when zeroing multiple scopes or red dot sights.

• Two batteries are included.
• Button switch for operation.

The kit also includes an arbor accessory for .551-12GA calibers. Installing it expands the rear end of the bore sighter so it fits better at the muzzle and improves stability. CVLIFE describes the kit as professionally crafted for long service life, with materials selected for its construction. It suits shooters who want a laser bore sighter with adapters across the stated caliber range and a setup that can support zeroing multiple optics. Its numbered adapters, red laser, and included arbor make it a fit-focused zeroing kit rather than a single-caliber tool.
