Sightmark Boresight 300 Blackout Red Laser Bore Sighter

The Sightmark Boresight 300 Blackout is a red laser bore sighter for aligning a rifle's sights with its bore. It is chambered like a normal cartridge, and the laser projects from the muzzle to show where the firearm is aiming. Used this way, it reduces the number of shots needed for fine-tuning and saves ammunition.

The unit is rated for a sighting range of 15 to 100 yards and displays a 2-inch dot at 100 yards. The red laser has a wavelength of 632 to 650 nm and uses less than 5 milliwatts, with approximately one hour of battery life. It has a brass outer case and an operating temperature range of 14 to 122 degrees F.

It is caliber specific and fits the 300 Blackout and 7.62x35mm chamber. The package includes a carrying pouch.
