Ruger American rimfire rifle serial numbers

I checked on the Ruger website and there are only two years posted.

830-00000 for 2013
830-42000 for 2014

Does anyone know of a more complete list that would include 2015 till now?

None that I know of.

Ruger has been using vendors to do receivers, but not sure if the American Rimfire Rifle is part of that or not.
That said, the AR556 for example has had several different vendors, and each is required to have a different prefix.
Needless to say, things are getting pretty confusing for dates of manufacture of Ruger firearms.
I do know American Rimfire Rifles are at least in the 834- prefix, but I can't say if the other prefixes have been filled out or not.
