Buying Guide

Match to your firearm caliber

Choose a boresighter sized for your rifle or pistol bore to ensure the laser seats securely and aligns with the barrel axis

Red laser vs. green laser

Red lasers are visible in most lighting and use less power, while green lasers can be easier to see at longer distances in daylight but often cost more

Check battery type and runtime

Prefer models that use common batteries with easy replacement and sufficient runtime for multiple zeroing sessions

Consider construction and fit

Metal or reinforced housings and tight tolerances reduce play in the bore and improve repeatable alignment

Look for handgun vs. centerfire versions

Pistol-specific boresighters have different shims or diameters than centerfire rifle models, affecting fit and accuracy
