I received my Teslong borescope, the flexible rod version and it is very clear, cannot believe how great the clarity is on something that is this cheap for scoping a bore.. So glad I found this one before I paid for the Lyman, however, looking at my 28 Nosler throat was a little fire cracked the riflings are around 1/8 inch gone, this is with around 300 rounds down the barrel.
