Saving money on ammo and time on zeroing your firearm has never been easier with the Accudot .243 Red Laser Boresight from Sightmark. Now with auto-activation that only consumes power and turns the laser on when the boresight is chambered, Accudots also feature a rechargeable, Lithium-Ion supercapacitor to keep you from buying hard-to-find batteries. A durable brass construction improves chambering and ejection, while an included USB dock allows for on-the-go charging. The Accudot .243 also boasts a calibrated diode to improve accuracy, allowing shooters to get on paper with their first shot. Accudots include recharging dock, USB cable, wall adapter and carrying case.
