Does the MR556A1 lower accept any/all "mil-spec" uppers?
I heard the first MR556 versions did not.
Your correct the A1 accepts any lower or upper.

I was told the real deal factory 11.6" is coming near the end of the year. The order is already made or will be made shortly by the distributor ( I forgot what exactly I heard ) They were just made available for ordering by HK Germany.
Haha, figures, it'll probably be less expensive, too... that would be just my luck...
