Sightmark® Laser Chamber Boresighters

• Calibre-specific laser boresighting aid that fits your gun’s chamber
• Use it to sight in, check your zero or practice aiming

Unlike other laser boresighting systems that insert into the muzzle of the firearm, these are precisely engineered to fit into the chamber, ensuring exact and consistent laser alignment with the bore. Sighting in your firearm has never been easier. Load the laser into the chamber, place the dot on a target downrange, align your sight’s crosshairs or dot with the projected spot. You’ll be boresighted and ready for live fire fine-tuning. You can also use this handy tool to check your zero after transporting your firearm to the range or hunting ground.
