No. It's 16, there is no R, even if you write it in bold and repeat it. It's a legal item to possess, like any other (unmodified) cyber limbs. To buy it, you just need a SIN, or a fake SIN that checks out. This goes around the rules for availability.
There is no availability test to be made for a legal item purchased normally.
The rules do state that the maximum availability of items is 12 at chargen, but the concept of availability in the first place is for black market goods. Otherwise, there is no availability test. As per RAW, it still seems that the cyberskull could be unallowed, but it's debatable. I mean, the description for cyberlimbs doesn't help clear away my doubts:
Looking again, I apparently did misread that, and the skull is just availability 16. Sorry about that!
That said, the spirit of the rule is pretty clear to me. Characters during creation aren't buying their gear on the black market, they're picking up base gear as background items. That, combined with the character creation chapter leaving used cyberware out in its list of available grades on p. 95, inclines me to go with 12 as a limit on the base availability of gear and 'ware at creation, not a limit on the modified availability. It's a mechanic to restrict purchases at character generation, nothing more or less, just like restricting devices to rating 6 even if they're affordable and legal beyond that.
There's a lot of stuff you can pick up legally that is out of reach at chargen, after all!

Not getting into the "SINners can buy whatever they want" argument, I thought there was something about "Used" cyberware being available out of chargen. Yes- the same sentence!
"Only standard, alphaware, and used implants are available for purchase at character creation" pg. 451
Yes, and :
QUOTE ("Page 95 @ Creating A Shadowrunner")
There are four grades of available cyberware and bioware:
standard, alphaware, betaware, and deltaware (p.
451). Only standard gear and alphaware are available at
character creation.
The book, as it often does, directly contradicts itself here. Hopefully someday we'll get actual errata on this stuff, but I'm not holding my breath.
