borescope

Hey guys, I just picked up a new 14.5" pinned and welded AR upper. It showed up yesterday and I planned to throw an optic on it last night and test it out at the range today. Out of curiosity I looked at it with my borescope before doing anything with it. I'm glad I did. I'm not sure what went...

Hi all, I have a Seekins Havak Hit in 6.5 cm and am cleaning it thoroughly for the first time. I have put about 380 rounds through the barrel and can't get the sucker clean. Under the borescope I found these weird "spots or patches". What are they and should I be concerned? Almost looks like a...

I bought a scope and figured I try it out on my semi new rem 700 5r 6.5cm with about 120 rounds thru it.. what’s those white lines? Video here thank, man so much info in this site..

I received my Savage Prefit .284 Win Shilen Select Match barrel today and took a video of the bore in case anyone is interested for future reference. I'm no professional, but the bore looks very good to me. I went back and forth checking the lands and grooves and couldn't find any defects worth...

Saw these from my new Proof SS barrel (6 dasher Impact prefit). Is it acceptable? First Proof barrel and not sure what to expect. Never saw these from my Bartlein :(

Used but not abused Gradient lens company Hawkeye borescope. I don't have a need for it anymore so lets find a new home for it. The mag lite is not LED, but it works just fine. Comes with everything pictured. No trades. I'd like to get 400$ Shipped lower 48. . Pay Pal F&F for payment...

My gunsmith recently notified me that i have a big carbon ring in one of my 6.5cm match barrels. Therefore i figured that i should get a borescope so that i can keep track of my barrels health better. I would appreciate some suggestions for an affordable borescope that works well.

I purchased this barrel from Optics Planet a month ago. It has not been used yet, just had a patch run through it. I just bought a borescope and had a look inside, I was quite surprised by the finish (Below is the video). So should I be concerned about the finish of this $350 barrel or not...

I recently purchased a Teslong Borescope and regretfully there is not a library of images on google to compare my barrels to. Please provide any and all feedback on what I am seeing in the below images. I am intentionally leaving out round counts on the barrels to not bias anyone's answers...

I was reading this article: http://www.realguns.com/Commentary/comar119.htm Did a bit of research and they have a higher resolution model (PV-2636). I'm wondering if anyone has tried one of these (or similar) in a 30 cal bore. I know it isn't a Hawkeye and that you only get what you pay for...
