Note that I do not have full historical info on RRA catalog items or how they varied over time. I can only give you a reasonbly informed personal opinion.
The RRA 'Varmint A4' is not
a listed entity.
I'll also add that a U15 stock also offers such a substantially different profile - plus a somewhat functionally-different buffer system - that even if rifle were
listed, I believe the newly-configured rifle would no longer be equivalent to the banned entity.
