Frequently Asked Questions

How does the Sightmark 9mm Laser Bore Sighter work?

The Sightmark 9mm Laser Bore Sighter fits directly into the firearm's chamber. Once batteries are installed and the cap is tightened, it projects a laser dot down the bore, allowing you to align your firearm's sights before live fire at the range.

What are the advantages of the Sightmark 9mm Laser Bore Sighter?

Its primary advantage is its chamber-based design, made of durable brass, which avoids the fragility of older arbor-style bore sighters. This ensures a more consistent alignment and greater longevity, saving time and ammunition during the zeroing process.

Can the Sightmark 9mm Laser Bore Sighter be used with optics?

Yes, the video demonstrates its use with a UTG 3-9x32 BugBuster scope mounted on a carbine. The laser dot helps establish a baseline alignment for the optic, reducing the need for extensive adjustments at the range.

What tools are needed to use the Sightmark 9mm Laser Bore Sighter?

The primary tool is the bore sighter itself, along with two AG3/LR41 batteries. While not strictly required for basic use, digital calipers can be helpful for verifying the precise 0.388-inch diameter fit against a 9mm cartridge.
