I bought this from rtb as well as one of their white label uppers in fde. This has a way better fit and finish compared to their house branded upper. I thought this was Aero Precision and mounted it on an aero, fit was great, again much better than their house brand.

I'm not sure about that. I think AO Precision/AO Inc. was founded in 1982. Aero Precision in 1995. Personally, I like AO and their industrial quality, and they've been making bcg's for the military for decades.
