It's not a matter of "loosely theoretically to the same specs." AR's from Bushmaster, Rock River, and DPMS are as alike as Remington M700's from different years or at different price points. It's not theoretical; the parts are completely interchangeable.Not apples and oranges at all. None of those AR15A2's are built with the same parts from the same company, while only loosely theoretically to the same specs.
So, was the "M1 Garand" the premier US .30-06 service rifle of WW2 through the early Fifties, or would you consider it more correct to say we issued the International Harvester Rifle, the Springfield rifle, etc. and treat them as independent of each other? Like M1 Garands, AR-15s regardless of branding use completely interchangeable parts. They are arguably more alike than early and late Winchester 94's.
The AR-15 platform is the top selling centerfire rifle in America. One can obscure that fact by pretending it is actually 30 different, unrelated rifles, but that doesn't really foster understanding, IMO.
