A bore sight - also spelled boresighter - is a precision alignment tool that projects a laser beam through the barrel of your firearm. By matching your scope, red dot, or iron sights to that projected point, you can get on-target from the very first shot rather than burning through a box of ammunition chasing a cold zero.

Whether you're zeroing a new scope on an AR-15, mounting a red dot on a pistol, or dialing in a rifle before hunting season, a laser bore sight kit is one of the most practical investments a shooter can make. It shortens the zeroing process from dozens of rounds to just a handful of confirmation shots - and that matters whether you're counting pennies at the range or simply don't want to disturb the woods before a hunt.

EZshoot has refined the boresighter concept over years of real-world shooter feedback, delivering tools that are accurate, durable, and priced for anyone from first-time owners to seasoned competition shooters. Their lineup covers everything from a budget-friendly 9mm bore sight under $11 to a professional magnetic universal kit with up to 64 adapters.

Boresighting sounds technical but the real-world process is refreshingly simple. Here's the four-step flow that works with every EZshoot boresighter.

There are plenty of boresighters on the market. Here's why EZshoot consistently earns repeat customers and 5-star reviews in the shooting community.

🎯 True Laser Precision

EZshoot uses tightly collimated laser diodes that maintain accuracy across distances. The dot stays tight, which means your initial zero is actually meaningful - not a rough approximation.

🔋Batteries Included

No frustrating "batteries not included" surprises. Most EZshoot boresighters come with the necessary batteries right in the package - including some kits that ship with 12 spare sets.

📐 Massive Caliber Coverage

Whether you need a 9mm bore sight for a Glock or a shotgun bore sight for a 12GA, EZshoot's catalog spans .17 to 12GA, including 6.5 Creedmoor, .308 Win, crossbow bolts, and more.

💡 Green & Red Laser Options

Green lasers are roughly 5× brighter to the human eye than red in daylight conditions. EZshoot gives you the choice - ideal for outdoor sighting sessions in bright light.

🧲 Magnetic & Button Switch Designs

Unlike basic tube-style boresighters, several EZshoot models feature a convenient button switch so you're never fumbling in the dark. The magnetic model offers tool-free setup across calibers.

💰 Outstanding Value

With prices starting at $10.99 for a multi-caliber laser bore sight kit, EZshoot makes professional-grade zeroing accessible to every shooter - from first-time buyers to armorers.

Not every bore sight works with every gun. Here's a quick framework to help you pick the right model before you click "add to cart."

If you own a 9mm handgun - a Glock, SIG, S&W M&P, or similar - the EZshoot 9mm Green Boresighter with 12 Batteries is the gold-standard choice. The bright green dot is easy to pick up even in daylight, and the generous battery supply means you won't be cutting sessions short. For a budget entry, the $10.99 cartridge boresighter covering 9mm, .223, 300BLK, and 7.62x35mm is a genuine steal.

Rifle shooters have the widest selection. The multi-caliber kit covering .223REM, 9MM, .40 S&W, .45ACP, .243, and .308WIN at $24.19 is an excellent all-rounder. If you shoot 6.5 Creedmoor or 6.5 Grendel specifically, EZshoot makes a dedicated cartridge bore sight for those chambers at $17.59 — and it fits precisely, which matters for accuracy.

The rechargeable 12 Gauge boresighter is particularly smart for shotgun owners who don't want to keep buying batteries. USB rechargeable, available in red or green, and priced at $23.09.

For gunsmiths, armory personnel, competitive shooters, or anyone who owns multiple firearms, the 64-adapter kit at $48.39 is the single best purchase you can make. It literally covers every common caliber from .17 to 12GA. The magnetic bore sight at $50.59 is another elite option — especially useful for calibers where a traditional arbor fit can be finicky.

Often overlooked, but EZshoot has a dedicated crossbow laser bore sight at just $16.79 - including two complete battery sets. If you're mounting a new scope on a crossbow before hunting season, this removes the guesswork entirely.

Does using a bore sight replace firing rounds to zero?

Not entirely - but it dramatically reduces how many rounds you need. Think of boresighting as getting you 90% of the way there. You'll still want to fire 2–5 confirmation shots at your desired zero distance and make final scope adjustments. The difference is you'll be on paper from shot one instead of missing the target entirely.

Is a green laser bore sight better than a red one?

Green lasers are significantly easier to see in daylight - the human eye is most sensitive to green wavelengths. If you plan to boresight outdoors in bright conditions, a green bore sight is the better pick. Red models work perfectly fine in indoor or low-light settings, and they tend to cost slightly less.

What's the difference between a cartridge bore sight and a universal kit?

A cartridge-style bore sight (like EZshoot's 9mm or .223 models) is shaped exactly like a live round and drops directly into the chamber - no adapters needed, and the fit is very precise. A universal kit uses a central laser unit with interchangeable arbor adapters for different calibers. Kits are more versatile if you own multiple firearms; cartridge styles are simpler and often more accurate for a single caliber.

Can I use an EZshoot boresighter on a semi-automatic pistol?

Yes. EZshoot's 9mm bore sight is specifically designed for semi-automatic pistols. You lock the slide back, insert the bore sight cartridge into the chamber, and sight in. Just make sure the firearm is unloaded and follow all standard safety procedures.

How far away should I place my target when boresighting?

For rifles, 25 yards is the most practical distance - it's far enough to matter but close enough that the laser dot is still visible. A 25-yard boresight on most centerfire rifles will put you very close to a 100-yard zero. For pistols and shotguns, 10–15 yards is more typical.

Are EZshoot bore sights safe to use with my optic?

Absolutely. Bore sighting is a passive process - you're simply aligning your optic to a laser reference point. There's no recoil, no pressure, and no risk to your scope or red dot. Always follow firearm safety rules: treat the gun as loaded until you've confirmed otherwise, keep your finger off the trigger, and never point at anything you don't intend to shoot.
