Laserlyte Cb-L368 Laser Cartridge Bore Sight Kit .223/.308/.3006
$130.49
The Laserlyte CB-L368 laser cartridge bore sight kit is a practical tool for rifle shooters who want to save ammunition and range time getting their scopes on target. Instead of firing rounds downrange to dial in your optics, this red laser bore sight fits directly into your rifle's chamber, projecting a beam down the barrel so you can align your scope or iron sights without a single shot. It's especially useful for hunters and sport shooters prepping rifles before season, or anyone building up a new setup and looking to verify zero efficiently.
The system centers on a .223/5.56 base laser cartridge that activates automatically when you close the bolt—no buttons to fiddle with. Once the laser is engaged, you can see the reference beam clearly enough in a darkened room or shaded area to work your adjustments. The kit includes adapter cartridges that let you swap to other common rifle calibers, so a single bore sight can service multiple firearms rather than buying separate tools for each chambering.
The laser output meets legal Class 3R specifications at 5mW peak power across the 630–670nm red spectrum, making it the brightest beam allowed under federal guidelines. If you're running LaserLyte training targets for dry-fire work, this bore sight pairs well with that ecosystem. It's a no-fuss way to get your rifle ready without burning through ammo or making unnecessary trips to check your zero.
