Many people in the US cannot afford that. It’s an arbitrary 33% increase on an already expensive purchase. That’s a pretty strong disincentive for a lot of people. Not to mention people who would prefer to engage with the federal government as little as possible, for a wide variety of reasons.
As for the definition, if you read the definitions of the prohibited components, they are broad enough to ban essentially all rifles, which is likely the goal. For instance, “pistol grip” seems like a well defined thing at a glance, but it is later defined as “ 45) The term ‘pistol grip’ means a grip, a thumbhole stock or Thordsen-type grip or stock, or any other characteristic that can function as a grip.”
That last clause especially is extremely broad. Define functioning as a grip. Is that any piece that enables holding the rifle?
