I had no idea the AR-15 and .223 were this powerful
I mean, yesterday's piece by Gersh Kuntzman told me that his bruised his shoulder, rang his ears through hearing protection, and just shooting it gave him PTSD. Now this piece tells the reader that the AR-15 "can shoot about 40 rounds per second. Hunters can take out grizzly bears with two rounds." 40 rounds per second -- that's take a very quick trigger finger, and being a bit faster on the magazine change than I am. At a cyclic rate of 2,400 rounds per minute, it'd make the MG-42 look slow. And hunting grizzlies with a .223 is apt to be overly exciting.
What all this illustrates is that we should arm our troops with the mindblowingly powerful AR-15, and let civilians have the popgun M-4s and M-16s and SAWs.
