Question: which Teslong are you all using? I see models ranging from $49 to $215. It would seem the simple 45" flexible scope would be the most practical and work on about anything.
I've got the cheapest flexible one. I think, Al mentioned he had a rigid model. I love the flexible one - great pictures. Just plug it into a lap top and have fun. Really helped getting down to bare steel before applying Dyna-tek Borecoat and also, polishing the throat on a new rifle. Seeing the tool marks before and after was pretty dramatic.
