Yugo Pitted barrel question

[Robidouxs]

I managed to come away with on excellent Yugo barrel, but the remaining two have pitting in between the rifling. I have tried scrubbing the pitting but it does not want to leave.

Are these two barrels still usable for building a complete AK? Any drawbacks?

Do a bullet test and see if it sucks the hole bullet. If it doesn't id say you would be good to go. If it does then sell them there are plenty of ak builders out there, or you could always just build a blast gun or blank gun with them.
