Overview
The Sightmark Laser Boresight (SM39017) is a caliber-specific tool designed for .45 ACP pistols to assist in zeroing sights or optics without firing live ammunition. Housed in a brass casing, the boresight chambers like a standard cartridge and projects a red laser dot to indicate the point of aim. It is factory-aligned, operates within a temperature range of 14°F to 122°F, and has a sighting range of 15 to 100 yards, producing a 2-inch dot at 100 yards. The unit is powered by three AG3 batteries (included) with approximately 1 hour of battery life. It comes with a carrying pouch and instructions.
