Dude, those questions could prove your point. You are too **** to honestly answer them. You arrogance and fear of being wrong prevents you from actually answering the questions.
Now answer the questions or leave with your head between your legs. If the AR 15 sporter was a battlefield field weapon the BATF would have classified it as such under the NFA of 1934. And considering the AR 15 was mass produced BEFORE the M 16 you would think this murderous battlefield weapon would have been issued to the troops.
So idiot, it is not a combat assault rifle. Never was and was not designed as such.
That shoots down your reasoning.
