Sightmark SM39019 Boresight Red Laser for .44 Magnum Brass

The Sightmark SM39019 is a cartridge-style red laser boresight machined from brass for a precise fit in .44 Magnum pistol chambers. Drop the tool into the chamber, close the action, and it projects a steady red laser point downrange so you can confirm or adjust sight alignment without firing live ammunition.

Rated for sighting distances of 15 to 100 yards and operating temperatures from -10 to 50 degrees F/C, the SM39019 is powered by three included AG3 batteries that deliver roughly 1 hour of active run time.

Out of the box, the kit includes a carrying case, the AG3 battery pack, and instructions, making it a quick and easy way to verify or correct sight alignment on any .44 Magnum handgun at the bench or range.
