I have never seen an assault weapon, do they look anything like defense weapons?
Here's one in the Democrat's eyes.
I have not idea what an "assault weapon" is, and I own many semi auto rifles.
But.... There is a rifle that shoots table salt... the A Salt Gun A Salt Gun (link)
That makes it "A Salt Weapon".... so that is close.
The Army has them, I’m told, but I’ve never seen one in the US.
