AimShot AR243 Arbor 243 Win Boresighter

The AimShot AR243 Arbor is a chamber-fitting brass arbor that expands the usefulness of your AimShot .223 laser bore sight module across a wide range of rifle chambers. Insert this precisely machined arbor into the chamber of a compatible rifle and it pairs with the .223 AimShot laser to deliver reliable alignment across a broad set of centerfire calibers far beyond its native cartridge.

Manufactured from 100% brass for maximum durability and concentricity, the AR243 provides a stable, repeatable seat inside the chamber so the laser projects a true point of aim. Once activated, you can confirm or correct scope, red dot, or iron sight alignment without firing a shot, saving both time and ammunition at the range.
