I'm afraid you are confused as to the definitions of various weapons. I'm also afraid I'll have to call you out on it, since I specifically mentioned the common definitional confusions in my first post in this thread.
So, let's go back. What is the definition of an assault rifle?
An assault rifle is a fully automatic or "burst-capable" rifle. The common American version is an M-16. This from wikipedia. These weapons are banned, as I indicated previously. This is not a question up for debate. Assault rifles, which are automatic weapons, are illegal in the United States.
Now let's look at the weapons that you linked to above... oh no! They are all semi-automatic weapons built to look like automatic weapons!
So, do you want to ban semi-automatic weapons? Do you want to ban semi-automatic weapons that look like automatic weapons? Do you want to ban just some semi-automatic weapons?
To be fair to you, it is a common misconception as to what guns are and are not banned in the United States, especially when one sees pictures of scary looking guns that look like they could fire off 50 rounds a second, but, well, they really can't.
I hope this helps you understand the whole situation better.
