Aim Sports PJBS223 Cartridge - High-Intensity 635-655nm 223 Laser Bore Sight with LR-41 Battery

The Aim Sports PJBS223 is a laser bore sight designed for shooters who need to get on target fast without wasting ammunition. This cartridge-style bore sight fits directly into the chamber of .223 Remington and 5.56 NATO rifles, projecting a bright red laser dot at 635–655nm wavelength onto your target. Whether you're zeroing a new scope, switching between rifles, or getting back in the saddle after storage, a laser bore sight cuts setup time dramatically and lets you dial in your optics on a target range or even in your driveway before heading afield.

Laser bore sights are especially useful for hunters and precision shooters who want a reliable starting point before fine-tuning on live fire. The PJBS223 uses an LR-41 battery to power the laser, so you can activate it, chamber the round, and see exactly where your barrel is pointing relative to your scope's reticle. Because it's a cartridge-based design, there's no fumbling with arbors or adapters—just load and go. The high-intensity beam cuts through daylight glare better than lower-powered alternatives, making it practical for daytime zeroing as well as indoor range work.

Keep in mind that a laser bore sight gets you close but isn't a substitute for actual shooting. Wind, bullet drop, and individual rifle/load combinations still require live-fire verification at your intended hunting or competition distance. But as a time-saving first step that eliminates the guesswork and wasted rounds, it's a smart addition to any shooter's kit.

Frequently Asked Questions

Will this laser bore sight work with my .223 rifle and 5.56 rifle?

Yes. The PJBS223 is compatible with both .223 Remington and 5.56 NATO chambers, so you can use it across rifles chambered in either cartridge.

How does a laser bore sight help with scope zeroing?

You simply load the laser bore sight cartridge into the chamber, aim at a target, and activate the laser. The red dot shows you where your barrel is pointing. Compare that laser dot to your scope's reticle to make quick mechanical adjustments before firing live ammunition, saving time and rounds.

What battery does it use and is one included?

The PJBS223 uses an LR-41 battery, which is included with the sight.

Can I use this laser bore sight indoors and outdoors?

Yes. The high-intensity 635–655nm red laser is bright enough for indoor range use and cuts through daylight glare well enough for outdoor zeroing during daytime.
