This boresighter for a 12-gauge shotgun features a heavy-duty 12 Gauge Red Laser Boresight housed in solid brass. The 12-gauge shotgun laser bore sight utilizes a Class IIIA red laser with a power output of 5 mW. How does a boresighter work for a 12-gauge shotgun? Simply load the 12-gauge cartridge laser bore sight like a standard 12-gauge shotgun shell, and a laser dot will indicate precisely where the shotgun is aimed. This allows for easy sighting of any scope without firing a single shot. Live fire is only necessary to fine-tune the weapon being sighted, compensating for factors such as bullet drop due to distance. The device requires three AG13 batteries, which are included. The 12-gauge laser sight bore sighter is pre-adjusted before leaving the factory, enabling quick zeroing and alignment with the target, thereby reducing wasted time and ammo.
