....in the vid the comments regarding "builder roots" gives indication of what Aero possibly views as their largest market, the DIY crowd. Due to Aero's manufacturing capacity AND capability, it's a reasonable thought that they will be able to produce some significant quantities of the subassemblies (receivers, chassis, barrels, etc.) in addition to complete rifles, just as they currently do with AR platforms. I would hazard an opinion that there are probably more Aero receivers out in the wild than any other single brand. The compatibility with Rem700 also links them to the myriad of aftermarket products and services (parts & smith work).
..as others have said, it's too early to make an informed opinion on the merits of their new venture. I don't shoot PRS/NRL or anything like that, but I do like to "tinker" and "build" my own...
