From my understanding of it, there is nothing about the gun in of and itself that is illegal, all it is a bolt gun with a bunch of doo-dad hangers attached to it.
Maybe in California though, seeing as how is has an adjustable stock and a detachable magazine. Not sure.
However, Remington Defense doesn't sell to civilians and they market said rifle, so whil not illegal, it's just not on the market.
