There is no such thing as an "Assault" Rifle. The term is nothing more than a fear-mongering form of virtue-signaling.
The term "Assault" is used to refer to rifles that hoplophobes (gun cravens) find particularly scary-looking. It is entirely an issue of superficial appearance and nothing more. Gun cravens simply hold up the visually intimidating-looking firearm before the nearest camera and ask their virtue-signalling-receptive gun-craven audience "Who really NEEDS one of these?" or "Should THESE even be legal?" without ever explaining how they differ from other firearms in any substantive way (because they don't). The purpose is to get an emotional reaction based on the extent it will frighten the most cowardly of society.
All politicians looking to ban so-called "assault" weapons are Leftists striving to disarm a free people, abolish the 2nd Amendment and usher in a tyrannical government. The whole issue is political and devoid of any substance of benefit to a free people.
Gun cravens usually "support" their fear-mongering with fabricated statistics that don't clarify what they are classifying as an "assault" weapon ... because there isn't any sort of firearm that constitutes an "assault" rifle beyond subjective appearance. All such statistics should be summarily dismissed.
