Building an AR10?

[everready73]

Thanks. I checked out their web page. They also have uppers and lowers. Any insight on the BA receivers? Are they as good/better that the Aero? It says they are DPMS pattern, but doesn't specify high or low.

I am betting that Aero is the OEM for the BA receivers. Aero owns BA so i would think they make these for them. Go with what is better priced or what rollmark you like better. All the Aero barrels in their rifles/uppers are all BA
