Gritr Lasersighter

Gritr Gear just launched a new multi-caliber, universal laser-boresighting kit that works in firearms with calibers ranging between .177 and .73.

Laser boresighters are a practical option to eliminate some of the guesswork when a new optic and rifle are paired together. Using the laser boresighting kit is easy because all the end-user needs to do is to install the corresponding size muzzle mandrel into the muzzle of their firearm and then attach the boresighting laser body to it. On a rest or off the bench, the rifle is then pointed downrange at the zero distance, often 50 or 100 yards. All the user needs to do is to reconcile their reticle by dialing it over to “meet” the laser.

While no laser boresighter will ever work as a substitute for shooting and zeroing rifles with their intended cartridges, Gritr guarantees that its new boresighting laser kit will get anyone within 5 inches of their actual zero.

Gritr Gear Laser Boresighting Kit Features

  • Includes a laser boresight, rechargeable battery, seven adjustable adapters, a screwdriver, and a hex key for convenient setup
  • Manufactured from T-6061 aluminum alloy with a matte black finish
  • Includes seven adjustable adapters that fit most calibers ranging from .177 to .78 (rimfire to 12 gauge), making it compatible with most pistols, rifles, and shotguns
