    i've used a 0.215 oblique view rigid borescope for decades (left over from my safe tech days and WAY more $ than the teslong endoscope) but was always sad that i couldn't inspect my .20 cal rifles with it. along comes the teslong with a measured 0.197 ferrule. YAY!

    the ease of use, documentation, picture quality and archiving, and price are all great selling points. have great photos of my 6mm's and 22 -250 carbon rings :( and was sure the .204 ruger was going to be even worse.

    then the cold water.... the 90* mirror would not fit in the bore. the mirror tube is indeed 0.197 like the cam ferrule, but the edge of the mirror makes max diameter 0.204. no fit....

    now i gotta think for a minute or two. i wrote this up so i wouldn't do anything impulsive in the mean time.

    I also ran into that with my 20 cal shilen. I just took off the mirror and did the look without it.

    I feel your pain. Mine was a humbling experience in that it proved to me that my cleaning routine was nowhere near what I thought it was...nor was the quality of some of my barrels. Thankfully :)oops:) it doesn't fit in my .17 Remingtons. I am terrified what I would find :eek:.

    Been using endoscopes for about 20 years now, my first one, and I still use it, is a Matco self contained unit similar to those you refer to. I've bought several others over the years, and they're an absolute necessity for gun cleaning, IMOP.

    BTW: also good for finding rat nests in walls. Don't ask me how I know. :mad:

    Going to order the one you recommend. Looks like a winner.

    Which model are you guys using, or is there only one, for rifle bores?

    What’s your carbon removal technique? Keeping them clean isn’t too hard for me, but I’m struggling with removal of built up carbon in a couple of barrels.

    Edit to add that I’m also using the Teslong Borescope. It’s the best $50 that I’ve spent in a long time.

    Looks like a good unit but the ad has three different sizes listed, .195, then a photo of .2 inch and finally at the bottom it says for all barrel larger than .223. Definitely written by someone with English as a second language. :rolleyes:

    Steve - there is no "rod" per se. It's all [semi] flexible cable. Nonetheless, between the two pieces of cable that comprise the unit, it is long. It will reach all the way through from one end of a 30" barrel. The drawback is that because the cable isn't perfectly straight like a rod, the camera head will flop around when you twist the cable to view the bore 360 degrees, going in and out of focus. The larger the bore is relative to the camera head diameter, the worse the problem will be. There are links to detailed reviews of the Teslong borescope here and on yesterday's Bulletin:

    http://bulletin.accurateshooter.com...orescope-works-great-full-review-with-videos/

    http://forum.accurateshooter.com/threads/teslong-bore-scope.3987243/

    The bottom line: the optics are very good and to get a usable borescope for $50, you're simply not going to beat that deal anywhere right now. For that price and having good optics, most people are willing to overlook a few minor design issues such as the cable flexing, etc.

    Mine is waiting for me at the house.

    Not sure if it will help me or just keep me from sleeping at night. Lol.

    well, right or wrong, i am using iosso on a nylon brush - short stroking just enough to feel the restriction as it enters the leade. i alternate that with rotating an oversize brass brush - by hand - j-u-s-t - into the leade. in my mind i see the brass brush creating miniscule ridges in the carbon that the iosso then polishes off.

    it is mostly all mechanical, not chemical, and i inspect frequently.

    I'm with Hogpatrol...the bottom of the ad says "barrel larger than .223".
    Let us know when you guys get them if they will actually will work in a .204
