Sightmark
Overview
The Sightmark Laser Boresight for 40 S&W Pistols is designed to help you quickly and accurately align your firearm's sights. Utilizing a boresight laser, this tool allows builders to ensure their optics are perfectly zeroed before live firing, saving both time and ammunition. While this specific boresight is tailored for 40 S&W pistols, builders often integrate similar sighting tools in AR-15 setups, particularly those configured with a Mid-Length gas system and chambered in 5.56 NATO.
