But the Feds define a rifle as a firearm so does it matter what the NY law defines? Unless they are defining it as something that is much more strict, which, as draconian as the gun laws are in NY, that wouldn't surprise me.
My point was to not make statements about gun laws unless you in fact know the law, and to demonstrate how common wisdom can be very legally wrong.
Wanna make it a serious matter? A "sawed off shotgun" is legal if made one way, and 10 years prison time if made another - identical parts used either way.
