Anyone hear of Grendel II using a 6.5x47 Laupa throat?

When was the barrel originally sold?

Here is what I was told when it was purchased:

I received the complete upper from AA Jan 2013. I can't warm up to the AA composite handguard so I took it apart and had the barrel fluted by ADCO. A new Midwest Industries gen2 10" handguard was installed.

So it must have been made in 2012.
