Aim Sports PJBS223 Cartridge Laser Boresighter .223 Rem/5.56 NATO

The Aim Sports PJBS223 is a cartridge-style laser boresighter built to take the guesswork out of sighting in optics on .223 Remington / 5.56 NATO rifles. Machined into a real brass case, it chambers just like a live round so windage and elevation adjustments can be made at the bench without ever pulling the trigger.

A bright 5 mW red laser fires down the bore at a 635-655 nM wavelength, putting a crisp reference point on the target for fast, accurate scope and red-dot alignment. The unit is powered by a compact LR41 battery for quick field setup and long shelf life between range sessions.

Whether you're mounting a new optic, swapping scopes, or just confirming zero after a trip, the PJBS223 is a simple, reliable alignment tool that gets you on paper in minutes.
