You try to talk about the danger to human beings, others want to shift the discussion over to talking about firearm technicalities. Then comes the claim that your arguments are invalid because you are supposedly not sufficiently knowledgeable about firearm technicalities.

Notice that the apologists or the AR 15 don't talk about velocity. What makes the AR 15 so deadly is the speed of the bullet, not the caliber, as well as the rapid fire capability.

"Any bullet can kill, and instantly, when it hits a vital organ. The higher speed of a bullet from an AR-15 causes far more damage after it hits the body and drastically reduces a person’s chances of survival."

A semi-automatic weapon like an AR-15-style one automatically reloads after each shot, and can hold around 30 bullets before the shooter needs to reload the gun. Besides its efficiency, what makes an AR-15-style rifle dangerous is that it has a higher muzzle velocity, meaning that a bullet travels nearly 3,000 feet per second. For comparison, a ​9-millimeter handgun's bullets travel at 1,200 feet per second.

Dr. Joseph Sakran, director of emergency general surgery at Johns Hopkins Hospital and a gun violence survivor, told Salon in an interview to think about the injuries sustained by an AR-15-style rifle as if there are two types of cavities created by the weapon.

"Depending upon the trajectory, if it goes through a named artery or a vital organ, you can imagine that trajectory of simply that bullet and that permanent cavity is going to cause life threatening damage," Sakran said. The second cavity he likened to when a big boat leaves behind a bumpy wake in a lake. ""You have bullets that are traveling at high speeds that result in a significant amount of energy distributed to the surrounding tissue, causing this temporary cavity that causes a significant blast injury that can be very, very deadly and cause significant injury."
