Who does Ballistic Advantage build barrels for?

Aero barrels for sure are made by B.A., and possibly RightToBear, but does anyone know of any other rebranded B.A. barrels, or are they making OEM barrels for any manufacturer?

Sons of Liberty Gunworks and AIM Surplus branded barrels are confirmed BA.

I think B Kings Firearms branded barrels are as well, but that's just an assumption based on comparing my barrels from each side by side. Finish, laser markings, etc. As well as how much BA and Aero product they sell.

I thought I'd heard that B.A. was an OEM manufacturer for someone...I thought it was Springfield Armory, but not sure.
