The Sightmark SM39018 red laser boresight for .38 Special and .357 Magnum is a brass cartridge that lets you dial in your revolver or handgun optics without firing a shot. Chamber it like live ammunition, and a red laser dot immediately shows you exactly where your gun is pointing. This cuts setup time at the range dramatically and lets you confirm your scope or sight alignment before you commit rounds downrange—ideal for hunters, sport shooters, and anyone who wants to verify their zero efficiently.
Boresighting with a laser eliminates the guesswork and tedious adjustment cycles that come with traditional bore-in methods. You'll know in minutes whether your optic is roughly on target, then use live fire only for final fine-tuning to account for bullet drop, velocity, and other real-world variables. That means less ammunition wasted on sighting and more rounds available for practice or the field.
This kit includes a battery pack to power the laser and a convenient carrying case, so you can transport and protect your boresight between uses. The brass construction is durable enough for repeated chamber cycling, and the .38 Special/.357 Magnum fit makes it compatible with revolvers and handguns chambered in those popular cartridges. Whether you're zeroing a new mount, switching optics, or just confirming your setup before a hunt or match, the Sightmark laser boresight saves time and frustration.
