TACFUN 12 Gauge Laser Bore Sighter – Quick Scope Alignment for Shotguns

Overview

The TACFUN 12 Gauge Cartridge Laser Bore Sighter is designed to slip directly into a shotgun’s chamber, offering a clear laser reference that mirrors the bore’s orientation. This tool is built to support a fast, practical sight-in process and helps you verify zero before a big hunt or a training session. With its compact form and straightforward operation, you can set up with confidence and move to shooting drills sooner.

Safety and control are part of the design. The device uses a Class IIIa 635 nm laser at less than 5 mW, bright enough to see the beam in daylight while staying within typical indoor and outdoor practice norms. As with any laser equipment, avoid direct eye exposure and handle with standard firearm safety practices in mind.

Key features

• Fits 12 gauge shotgun chamber, providing a direct bore reference for alignment
• Made from durable aluminum, offering a sturdy feel and reliable field performance
• Extremely useful for initial scope sight-in, or to confirm zero before the big hunt
• Projects the exact alignment of the bore to simplify cross-checks against your reticle
• Six batteries are included, so you can start using it right away

Usage and benefits

In practical terms, the bore sighter helps you visualize where the bore points before you adjust scope turrets. The result is a more efficient setup routine, whether you’re at the bench or in a light field environment. It’s a tool for planning and verification, not a guarantee of performance, and it complements your normal sight-in workflow.

What you can typically expect is a clearer path to aligning reticles with the bore’s trajectory, plus a convenient way to run quick checks when time and conditions matter. While outcomes vary with individual firearms and optics, many shooters find the device helpful for reducing first-shot guesswork and confirming basic alignment prior to hunting or practice sessions.

Fast setup tips

• Unload the shotgun, insert the bore sighter into the chamber, and switch it on
• Project the bore line onto a target and compare with your sight picture
• Adjust scope or sights as needed and re-check for consistency
