Ok here we go.
I might not get these all correct, I'm not a gun expert.
I'm only going to answer the last 4 like CC said.
Key: Legally owned. Since 1934, two. However, my data on the subject ends after 1994, so I'm limited on the info.
Uh...Handguns
Long guns, Rifles, shotguns, Machine guns, Submachine guns, Assault rifles? I think I'm missing one.
Submachine guns are smaller and shoot a pistol round. They generally are fully auto with a high rate of fire, but have a smaller rate of fire. Assault Rifles are larger and shoot a rifle round. They generally are NOT fully auto (although many can be) with a slower rate of fire and much higher accuracy.
LMG's typically are used by an individual. If I remember it, A squad assault weapons needs a second guy.
I'm not a supporter of gun control supporter, but did I win?
