ArmaLite Floating Rail System

Is Armalite selling their new FF rail system as an upgrade or separately? Or is it only available on their SASS AR10?

http://www.armalite.com/sales/catalog/ALOSTYR.htm

They are advertised as fitting the .223 and .308 rifles. $215 for all lengths.

EDIT - on second inspection, these are two piece rails. Probably not what you’re looking for.

I understand that it is part of the SASS system.

LaRue, SWS, and DD make EXCELLENT ArmaLite rails.

I think TROY makes them ? or they are working on them (or was when I left). They made some for last years SHOT and I think COBB had a version of it at this years SHOT…
