I have a spec on my scope that appeared a couple months back. I finally had the time to look at my scope and make sure the speck was not on an exterior lens, (its not). While doing this I learned the inside of my scope has MANY stray particles. The inside of the tube even has what looks to be dried water marks. I took these two pictures the other night when I was off, had to hold the gun, flash light and camera it was fun. The think the spec is one of the “stray” particles from the inside of the scope. There are so many I have not even tried to count them. Very disappointed. I will contact Vortex and see what they have to say about this spec and the stray particles. I am not a happy camper.
