Sorry in advance if this question has been asked / answered before, but a search didn't seen to provide an answer. Got a Teslong borescope and, having never used one before, wondering precisely where one should be looking for any indication of a carbon ring? Is it where the rifling ends, where the barrel joint meets the receiver? Any other insight, tips are greatly appreciated. Thanks for taking time to all responding.
 
A quick search in the search bar at the top of this site would get you the info, I looked for “carbon ring” and found several good threads, including this one:

There are 2 camps. One never cleans a rifle. Then the other camp it gets scrubbed out after every time out or more. Speedy was talking about thing a few days ago about sometimes if the carbon ring is there too long you cant get it out and it actually hurts accuracy and you can never get the barrels to shoot up to its potential if you don't clean it. He was talking about someone that did not clean regularly and the barrel shot out faster than the other barrel the guy had that he cleaned the carbon ring after each set in a match.

The teslong is a good scope to see what is happening.
