I have brought over at least a dozen scopes in carry on.

I agree it depends upon the TSA agent. Thats a wildcard today without any consistency of what the regulations are. It's also a bad place to have to have a debate. Time wise you better be ready to wait on the opinion of a supervisor that may be across the airport or off site.

The only time there was a momentary hesitation on the part of the TSA for me, I simply said, " It's no different then a telephoto lens for a camera" and the lady said Yes I suppose thats right.
