SiteLite Laser Boresights

SiteLite Professional Laser Boresighters Buyer's Guide

SiteLite magnetic laser boresighters are designed for shooters who want faster, more accurate scope alignment without purchasing a different cartridge-style boresight for every caliber. Unlike chamber-style boresighters, a single SiteLite works with rifles, handguns, muzzleloaders, and many shotguns by using a magnetic arbor and caliber-specific O-rings.

Why Choose a Magnetic Laser Boresighter Instead of a Cartridge Boresight?

One Tool Works with Many Calibers

Caliber-specific chamber-style boresighters have several shortcomings. Each has its own batteries, which can die at the worst possible time, and they put you in a position where you're trusting the cheapest mass-produced tool to calibrate a precision shooting instrument.

No Chamber-Specific Cartridges

SiteLite boresights work with a wide range of calibers. There is no need to purchase a separate chamber-style boresight for every firearm in your collection. SiteLite systems work with pistols and rifles with barrels over 3 inches, as well as other supported firearm types. Because the laser does not use the chamber for alignment, it avoids inaccuracies associated with tolerances between a firearm's chamber and a caliber-specific cartridge boresight.

Centers in the Bore with a Magnetic Arbor System

Using the correct O-ring to keep the boresight snug in the barrel helps the magnetic arbor center the laser in the bore, allowing the laser to track with the bore's centerline.

Useful for Rifles, Pistols, Muzzleloaders, and Many Shotguns

Whether you're working with a .45 1911, a 12-gauge shotgun, or a .50 caliber muzzleloader, a single SiteLite boresighter can help you establish preliminary sight alignment across multiple firearms, provided you use the appropriate setup.

Which SiteLite Laser Boresighter Should I Buy?

Model Laser Color Best For Recommendation
SiteLite SL-100 Red Occasional shooters A good starter model for budget-conscious shooters and casual hunters.
