Does anyone know if the SR-556 is mil-spec?

These guns are not mil-spec they're what they call it commercial spec gun. An upper will fit any lower but it's just not quite the same if you know what I mean ... The takedown models about anything you really want to do with them they have to be sent back to the factory
