Bore scope,...help needed.

[Rustystud]

I bought The Gradient Lens Co., 21" kit, it came with a 21" scope with the 45" sleeve, a 7" scope with a 45 degree sleeve, two lights, and a 45 degree eye piece, a case and lots of q-tips and cleaner solution. The next year I bought the camera adapter and comparator computer software. I bought mine direct from Gradient lens at the Shot Show.
