What barrel is this?

I want to say it's a lapco... But it has no markings at all
it's short, about 10" and AC threaded.

To me, it looks like an autococker Vortex barrel that has been chopped and custom ported. LAPCO typically ports behind the fluted section. But I am honestly not sure.

At the very least it looks like a barrel that was intended to have the AC shroud placed over it judging by the 2 sections of increased material

Stock WGP STO barrel from the 90s.

I pulled it off an automag lol. It's a neat barrel.

I was going to say Taso Power barrel, but I didn't think they ever ano'd those.
