AimShot MBSKIT3 Modular Rifle Boresighter Kit 243 Win/308 Win/7.62x54mm Chamber Brass

The AimShot MBSKIT3 is a modular rifle boresighter kit built around the BS223 red laser bore sight module paired with brass chamber arbors to cover the .243 Winchester, .308 Winchester, and 7.62x54mm chambers in a single bench setup.

The kit centers on the BS223 red laser bore sight module with separate brass chamber arbors - the AR243 and AR3006 - sized for the included calibers. Each arbor seats directly in the rifle's chamber; once the laser is activated, the beam provides a quick visual reference for aligning scopes or iron sights to the bore without firing a round. The chamber-mount design makes the system fast to set up at the bench or in the field, and the separate laser module and arbor pieces keep the kit genuinely modular across rifle platforms.

Power is supplied by readily available LR41 button-cell batteries, and the system is purpose-built for scope alignment and boresighting on rifles chambered in .243 Winchester, .308 Winchester, and 7.62x54mm.
