I would first like to say thank you for taking the time to read this post, with that please forgive me if this has been asked and answered. I searched the site for the answer with no luck. So here we go, this evening I was laser bore sighting my new rifle and noticed that while I was looking through my Vortex Crossfire 6x22x50 every time I moved my head the red dot(from the tool) would also move thus causing me to set and reset the scope. What would be the cause of this? I placed the bore sighting tool into another rifle with a Millet scope and this did not exist at all.
