AimShot Rifle Arbor Features The AimShot Rifle Arbor is designed specifically to adapt any AimShot .223 laser bore sight for use in rifles chambered in 6.5 PRC or .300 PRC. Rather than requiring a shooter to purchase a dedicated bore sight for each new caliber added to their collection this arbor lets an existing .223 bore sight serve double duty across these larger chamberings. The adapter is built to fit precisely into the chamber of a 6.5 PRC or .300 PRC rifle holding the bore sight in alignment with the bore for an accurate read. This approach saves money and simplifies the bore sighting process for shooters working with multiple rifle calibers. Because the arbor is a simple purpose built adapter rather than a standalone bore sighting tool it is compact and easy to store alongside other range and reloading equipment. Using the arbor follows the same straightforward process as using the .223 bore sight alone with the arbor simply inserted into the chamber before the bore sight is placed. This makes the sighting in process faster for anyone who owns multiple rifles across different PRC chamberings. For shooters looking to extend the value of an AimShot .223 bore sight to additional calibers this arbor is a practical low cost accessory.
