Need your advice on barrel borescope image

[Lmi3]

Hi Guys,

I just bought a borescope, and I wanted to check my barrel before I start cleaning.
what is this ?

FYI
Rifle : AI ATX 6.5 CM (about 200 rounds )

1. Corrosion
2. Hard carbon

It's best to inspect after a cleaning as well. Sometimes there can just be crud and it cleans out.

Hopefully you measured where it was.

Now, clean your barrel thoroughly and look again. I agree with the corrosion and hard carbon assessment above.

Your barrel will otherwise be fine.

Thank you
Is it normal to see corrosion after 200 rounds ? Or am I doing something wrong ?

Depends on your conditions you've got it in man. If you let some moisture get down the bore, or took it out from a cool house into a hot afternoon and let it condensate etc...

Stainless isn't impervious. But it is a lot more resistant than carbon steel.
