[Uncle Billy]

You can't shoot a lever gun with one hand rapidly while charging someone shooting at you, unless you're in the movies or on TV. Ask the combat people clearing a village what sort of weapon they'd rather have than the ones they do. They got the name "assault" weapon because they were designed to be effective and easy to use when making assaults in combat operations. "Assault" weapon is a nickname, not an official designation, and what it's best suited for can be seen clearly by its configuration.
