Precision Boresights for Every Caliber
Whether you're a seasoned marksman or new to shooting, a properly aligned optic makes all the difference downrange or in the field. Sightmark offers a wide range of laser boresights for rifles, pistols, rimfires, shotguns and archery, so you can line up your sights fast and spend less ammo getting on target.
Versatile Boresights for Every Firearm
No matter what you shoot — the all-American .223, a .30-30 Winchester from the Old West or a World War II-era 7.62x54mmR Mosin Nagant — Sightmark has a boresight for it. The lineup covers rifles, pistols, rimfires, shotguns and even archery, so every shooter has the right tool for accurate alignment.
Universal Boresights for Unique Calibers
For rare or obscure calibers, Sightmark offers a range of universal boresights. They fit a wide span of bore sizes, so even niche firearms can be boresighted without compromise.
Reliable Accuracy for Seasoned Marksmen
For experienced shooters, consistency is everything. Sightmark boresights give you a reliable starting point for precise alignment, taking the guesswork out of mounting a new optic and reducing the number of test shots needed to dial it in.
Beginner-Friendly Tools for Confident Shooting
New to firearms? Sightmark boresights are simple to use. Drop one in, line your optic up with the laser and you're close to zero before you fire a single shot — then confirm at the range. It's an easy way to build confidence in your gear from day one.

Frequently Asked Questions
What does a boresight do?
A boresight projects a laser that lines up with your barrel, so you can adjust your scope, red dot or iron sights to that point before you fire. It gets your optic on paper quickly and cuts down the number of rounds it takes to zero.
Do I still need to zero at the range after using a boresight?
Yes. A boresight gets you close, but you should always confirm and fine-tune your zero with live fire at your chosen distance. Starting from a boresighted optic means fewer test shots and less wasted ammo.
What if Sightmark doesn't make a boresight for my caliber?
Choose a universal boresight. Sightmark's Universal Boresight and Triple Duty Universal Boresights fit a wide range of bore sizes, so rare and obscure calibers can still be boresighted.
Which firearms can I boresight with Sightmark?
Sightmark makes boresights for rifles, pistols, rimfires and shotguns, plus an arrow and bolt boresight for archery. Popular options include .223/5.56 NATO, 9mm Luger, .308 Winchester, 300 Blackout and 12 gauge.
What batteries do Sightmark boresights use?
Most Sightmark boresights run on AG5 or AG3 button-cell batteries, and a couple of models are rechargeable. Check the product page for the exact battery your boresight uses.
