The SIGHTMARK 45 Auto Boresighter is a self-contained system that projects a red laser for easy sighting without firing a shot, compatible with various sights.
Constructed from durable machined brass, the boresighter resembles a cartridge case containing the laser system and batteries, with a simple on/off function.
It includes a nylon carrying case for portability and is available in multiple calibers, with the .45 Auto model also fitting other specific caliber firearms.
