The only significant way this rifle is "like" the one used at Sandy Hook is that it has a superficial visual similarity.
Not to mention the obvious fact that neither of these guns is an "assault rifle."

Allows sidearms to be drawn in to whatever ban gimmick they have in mind.
My 1911 is an "assault weapon" (semi-automatic)?
