Could be anything from what's advertised to a basement bubba build. Even if you see a rollmarked barrel ID, that might be the only part that actually came from that maker. I've got a couple of AR types that have Colt rollmarked barrels. That's the only Colt made part on the entire upper and it was a takeoff hand-me-down.
If you don't/can't believe the seller's descrption and will be disturbed by the possibility that it's false, don't buy.
For those with "logo ego", just tell your buddies it's whatever you want it to be since darned few could tell the difference anyway.
