SightMark Laser BoreSight – .38Sp / 357

The Sightmark Laser Boresight is a practical and accurate tool designed to simplify the process of zeroing most pistols. It is inserted directly into the chamber in the same manner as standard ammunition and projects a visible red laser point that shows the firearm’s point of aim. This allows users to align their sights or optics quickly without the need to fire live rounds. Minor adjustments with live fire may still be required to fine tune accuracy and account for factors such as distance and bullet drop, but the overall amount of ammunition needed is significantly reduced. Suitable for hunters, competitive shooters, and law enforcement professionals, this boresight helps eliminate much of the time and expense typically associated with sighting in a firearm. Its compact and lightweight construction makes it easy to transport, and it includes a protective carrying case for secure storage and field use. The unit features a visible red laser with a wavelength of 632–650 nm and a power output of 5 mW, operates using AG5 or AG3 batteries with an approximate one hour battery life, provides a sighting range of 15 to 100 yards with a dot size of approximately two inches at 100 yards, is activated by an on/off end cap, is constructed of durable brass, and is designed to function in temperatures ranging from -10°C to 50°C.
