Review on Accurately Sight In Your Shotgun With The Sightmark Red Laser Boresight by Suhas Carney

I bought this for a 2x use (Remington slug guns). Using a laser range finder, I pointed the SightMark boresight at a bright shiny hubcap at 50 yards. Invisible; fair enough. It was sunny/bright outside. I then tried a series of bright objects at 25 yards; still nothing. In desperation, I taped a 8.5" x 11" piece of bright white laser bond paper to the outside of a car window, again at about 25 yards. I took the boresight out of the shotgun, and walked to the car. At 3' from the paper the red dot was visible, but faint. Five-steps steps back, less than ten feet away, the red dot disappeared from the paper. This would be very discouraging if you tried using this bore sight at a range, with paper targets.By accident, while swinging the shotgun, I noticed that the red dot reflected brightly off a white license plate, on a pickup truck maybe ten feet away. So I tried the boresight aimed at the license plate at about 15 yards, and it was still visible. I pointed the Remington at the license plate; the TASCO red dot scope was right next to the boresight red dot, although the boresight dot was fainter. Fifteen yards is enough to get me on paper at the range.The issue with this Sight Mark is reflectivity (I assume with all lasers). As an aiming point, glossy white painted metal is way better than absorbent paper, no matter how bright the paper is. The other trick is to start very close, feet away, and work back until the dot disappears.Good luck.
