So the that makes the AR-15 purely designed for killing people? And that's different than many other guns? I hate to keep beating a dead horse here, but this is such a simple point and you guys are so stubbornly refusing to acknowledge that was a dumb thing to say.
the ammunition, form factor, mechanism, were specifically optimized to meet the requirements of the us military for a battle rifle. nobody is explaining this to you because they would rather see you drown in a pool of your intellectual dishonesty
