A wise guy would say, yup they are just as destructive. We better ban them both.
But I have to say that this guy completely misses the point. The idea is that they figure that the gun equipped with adjustable stock, pistol grip, and flash suppressor makes the gun easier to handle in an assault type situation. And the flash suppressor makes the gunman harder for swat to locate and take out. He does seem to think he's pretty smart though judging by his sarcastic demeanor. Pretty comical that he thinks that politicians wanting to ban those accessories has anything to do with "knockdown power."
