The AimShot Laser Boresighter (brand part no. BS223) is the base module for AimShot’s entire rifle-caliber boresighting system. Built for .223 Rem/5.56 NATO chambers, it mounts directly like a cartridge and projects a laser down the bore for a fast, no-adjustment zero. Because it’s the foundation module, this same laser pairs with AimShot’s full line of caliber arbors to cover everything from .243 Win to .30-06 without buying a new boresighter for each rifle.
