I just ordered one. I've been looking at the different videos that various people have made. None so far have actually shown it in use. I had another brand of similar boresighting equipment, which didn't work worth doo doo. I want to see someone put on a adapter for a specific caliber and shove it down the barrel just to see how stable it is. The previous brand used rubber o-rings. You used two, one at each end of the rod that goes into the barrel. There were notches in the rod where the o-ring were to stop. That didn't work so well because, even after lubing them, they would still come out of the notch, and that would cause the laser to be wobbly in the barrel. Also, with the other laser boresighter, I had to spend nearly two hours to center the red dot with in the actual laser it self. I hope this thing works as intended.

Thanks

How much was it? Are you doing any videos on actually using it on a rifle ?
