Laser was off zero which makes the product useless. - Bushnell Laser Boresighter w/ Arbors

If you roll the laser on a flat surface, you can see if it is on point or not. Mine was making a 12” circle at 25yds. The arbors supplied do not work for a 12g shotgun, unless maybe mine was just missing pieces— if you roll a napkin around the arbor it will work just fine afterwards if the laser was on point. You can check by rolling the laser on a flat surface and checking on the wall for rotation, which this one also did. I learned that if you mapped some points on it’s rotation and then ran a line through them on a paper you would find the center of the laser and you could make it work then, but they could’ve also just sold you a good product. Maybe there are other ways to make this crooked laser work, but all of which are compensating for a poorly designed, or loosely QC’d product. The positive reviews might have gotten lucky with a straight laser, but if you are not, then you have an overpriced fidget toy.
