A .223 Remington chamber laser bore sighter is a quick way to get your rifle on target before you head to the range or into the field. The NcStar laser bore sighter drops into your chamber and projects a laser beam down the barrel, letting you dial in your scope without burning through ammo. It's a no-nonsense tool for hunters and shooters who want to save time and ammunition when zeroing a rifle—especially useful if you've just mounted a new optic or swapped barrels.

Built with brass construction, this bore sighter is designed to handle repeated use and chamber fit. It comes with batteries included, so you're ready to use it straight out of the box. The design is straightforward: insert it into the chamber, activate the laser, and use the visible dot to align your scope crosshairs at a safe distance. It's a field-proven method that works well for initial bore-in before fine-tuning at 25 or 50 yards.

This tool works specifically with .223 Remington rifles, making it ideal for AR-platform shooters, varmint hunters, and anyone running that common chambering. Whether you're setting up a new rifle, troubleshooting a scope mount, or just want to confirm your zero after transport, a chamber laser bore sighter cuts the guesswork and gets you closer on the first shot.

Frequently Asked Questions

What caliber rifles does this bore sighter work with?

This NcStar laser bore sighter is designed specifically for .223 Remington rifles. It will not fit other calibers.

Does it come with batteries?

Yes, batteries are included with the bore sighter, so you can use it right away.

How do I use a chamber laser bore sighter?

Insert the bore sighter into the rifle's chamber, activate the laser, and align your scope's crosshairs to the laser dot projected downrange at a safe distance (typically 25 yards or more). This gives you a preliminary zero before you move to live-fire verification at the range.

Can I use this for final scope zeroing?

A laser bore sighter is a starting point for alignment. Always confirm your final zero by firing shots downrange, as bore sighter alignment and actual point of impact can differ slightly based on distance, barrel length, and ammunition.
