This is a borescope vid I shot of one of my AR barrels. The barrel is 16” in length, has a 5.56 chamber, 1-7 twist, and is chrome lined. It has ~150 rds through it. This is a factory upper from a reputable manufacturer. I’d just like some opinions on the current state of the chamber and rifling based on the low round count (150 rds). I’m not having any issues whatsoever with the rifle.

I’ve learned not to use my bore scope unless there’s already a problem with the firearm, it just makes me paranoid.
I'm not having any issues but need to know if I can bitch about this.
If you weren't having issues, why did you borescope it?
If you don't know how to interpret what you see, why did you borescope it?

Replying to all: The reason for the borescope was for two reasons: I bought it used with a claimed 80rds, with me putting an additional 70 rds through it. Comparing to other rifles I have, the chamber and rifling looked rough. Secondly, this company is know for throwing sloppy seconds out to the civvy world, and was just curious to whether or not that’s what I got.
I saw no problem either other than what I thought was a rough chamber and rifling.
Soooo, did you get what you expected?
To me the chamber looks a bit rough but the rifling looks ok...if it shoots good, which is the only real test worth a damn, what's the issue?
I have a bore scope...I use it to evaluate my cleaning. I have a Proof SS barrel with right at 2k rounds on it that looks like shit inside but still shoots just as good as when new. YMMV

It doesn’t give me any problems. But after testing accuracy with BH Mk262 OTM, S&B 77gr SMK, Pine Valley 77gr SMK, & IMI Razorcore 77gr OTM I’m less than satisfied. Which left me wondering if the condition of the barrel might be to blame.
I'd try rolling down in weight as it may not like heavier pills?
So, what would satisfy you? What are your expectations? Are you confident you can outshoot the gun?
I miss the days when borescope prices were high so people just went to their range and shot their guns to see if the barrel was good or not.
Yeah, those are all "decent" ammo and should give "decent" accuracy. Perhaps the previous barrel owner decided that it wasn't up to par and pawned it off.
Ain't that the truth! LOL! @bigjake83 allowed me to borrow his scope for a few days. Thankfully, he had given me a tutorial on how to interpret the various visuals provided by any given barrel. I think I would've figured it out, but I could see how some OCD-prone folks could misinterpret some unknown/anomaly in their barrel(s).
It is nice to be able to see this level of detail in our barrels, but at the end of the day, if I had a barrel that shot well, I wouldn't give two shits if I scoped a barrel and it was missing half the rifling. HAHA!!
OP - what were the results of your testing those various types of ammo? What was your expectation of the rifle's capabilities? I'm a fan of KAC's hardware, but I also know, generally speaking, that they are not precision rifles.
still waiting to see cave writing on one of these video's pictures of animals on the cave walls lol native American pictographs of past hunts inside the barrel of someone's gun , maybe a map to the lost location of the holy grail . Every dog finds a bone once in a while .

You bought a borescope and put a video out online. Neat!
I remember observing a group borescoping a lapped bore on a big 32" monitor. They were fixated on lines on lands running parallel with bore axis. Im chuckling. Finally one turns around and asks me 'JR, what are these marks?' I said 'its drag lines from the borescope fingerblasting my lapped barrel. So stop it. '
Fingerblast. You must be young. Story to be told is nunya have the chops to see an accurate bbl thru a borescope. I dont even. But it is cute to watch those who try.
Ive never borescoped a barrel for accuracy.
