Query: Not that good!

I had attempted to use this bore sight on my 2 scoped rifles and was quite disappointed. First off the arbors don't fit properly and cause the optic sight to rotate around while aiming in, next and most important is that the grid pattern inside is way off. You can pull the bolt and get a better sight in. Asked for a refund and was given an RMA# but my buddy wanted it so I gave it to him.
