RA, I could only find something on Miruku rifles, but not much, just obscure references. As for the Vanguard line, I think you may be right since I just received their catalog and they even have a sub-moa "model" now that is guaranteed to shoot as the name suggests sub-moa (duh). I doubt they would do that on something that someone else builds, but who knows nowadays. Marketing promises and engineering has to deliver.
