Got one of the cartridge style laser bore sighters last week and "sighted in" two ARs from my garage. I had waited til nearly sundown and used my range finder to pick out a spot down the street as close as I could get to 100 yards. Had the upper in a vice and just looked through the scope and turn windage and elevation until the crosshairs sat right on the lazer dot.
Got out to the ranch this weekend and because I didn't trust that process, we set up a 100 yard sight-in target. 4x4 plywood with several targets taped on. Neither rifle was even on the board from 100 yards. I ended up having to walk-back sight them starting from 25. In the end both guns were grouping well so I know I was not having any mount issues. One gun is suppressed but the other is just a standard 5.56 carbine length barrel. I can understand POI being different on the suppressed gun but on the other one I'm really baffled.
How could that laser be so far off?
