Sightmark Boresight Red Laser 12 Gauge Laser Bore Sight

The Sightmark Boresight is a 12 gauge laser bore sighter that fits into the chamber like a normal shotgun shell. When chambered, it projects a red laser out of the barrel, showing where the shotgun is aimed so the sights or optic can be adjusted without firing many rounds.

The laser has a wavelength of 632 to 650 nm and uses less than 5 milliwatts, with approximately 1 hour of battery life. It works at ranges from 15 to 100 yards and displays a 2 inch dot at 100 yards. The brass outer case is rated for operation from 14 to 122 degrees F.

This bore sighter is caliber or gauge specific and is sold with a carrying pouch.
