Massachusetts Attorney General Bans Sales of All "Assault Weapons"

According to Attorney General Maura Healey (LINK):

The directive specifically outlines two tests to determine what constitutes a “copy” or “duplicate” of a prohibited weapon. If a gun’s operating system is essentially the same as that of a banned weapon, or if the gun has components that are interchangeable with those of a banned weapon, it’s a “copy” or “duplicate,” and it is illegal. Assault weapons prohibited under our laws cannot be altered in any way to make their sale or possession legal in Massachusetts.

I wonder if this means that even say bolt-action or pump-action rifles that say take AR-15 magazines are now considered "assault weapons" because the AR magazine is an "interchangeable component." Also, how does one define "interchangeable component?" Does that include things like screws? A sad day for civil rights in Massachusetts.
