You don't need an assault weapon with muzzlebreakers to pop tires, a musket is just fine for that.
In all seriousness what's the reason for the change?
I am a professional. I always aim true whether firing single rounds or full automatic. I know neither fatigue nor failure. I would take pride in my work but for one thing, I do not know my target. I am not the one that kills. That distinction belongs to the man who pulls my trigger. I am an assault rifle. My name is Kalashnikov.
