You might want to look up definitions when making your anti-gun lists.
Fully automatic Weapons & Machine guns?
Fully automatic weapons are low caliber machine guns, effectively one in the same. Not owned nor available to your average citizen.
x2 sniper rifles?
Was it repeated for emphasis?
Do you know what they are?
Virtually all hunting rifles fit the definition.
They save your hearing but they don’t silence the sound like in the movies. They are readily available to criminals yet rarely used.
Armor piercing rounds?
They really aren’t an issue, why are you worried about them? Can you name a single example where the police were shot with one via a handgun? Most rifles are already armor piercing.
