I posted in GD not knowing this was a retro barrel. They are telling me Dutch. Its a 20" with a target crown that used to have an A1/A2 sight post on it. Its not a Port/Sudanese as far as I can tell. I saw a picture of a rare KLM AR10 that had a similar bare/target crown but they were all 16" I think. Not really sure what I have...anyone have anything they can add?

The general shape of the barrel extension matches what one would expect on a Transitional or Portuguese AR10.
Check the barrel extension diameter, for Dutch AR10's its is 1.20" |

The interior of the extension looks AR15-ish. The exterior looks Dutch-ish.
If the exterior diameter is 1.1" then its AR15. 1.2" means Dutch Or the barrel could be for a modern 308 rifle, such as the LR308 from DPMS. That would explain the front sight base.
