17 caliber borescope

[barm]

Do any of you have a borescope which works for 17 caliber barrels? If so, which one do you use and how do you like it? I have a Lyman borescope which I like, but it will only do 20 caliber or bigger.

I haven't found one, my Teslong also only goes to 20 caliber. I thought I found one, but upon further exploration it would not use a 90 degree side mirror, which made it useless. I got a forward looking one off Amazon, which was useless as well. I'm curious for an answer as well!
