An AR-15 does not have a faster rate of fire than a Ruger mini-14, a traditional hunting rifle. Nor does it function any differently. All differences are purely cosmetic. Such as pistol grips, collapsible butt stocks, and flash suppressors.
And yes, an AR may be geared towards combat and less so for hunting (although I know a lot of people who use it for hog hunting and small game), but our 2A rights were built around the rights of citizens to have weapons for combat, not just hunting.
And this stuff isn’t semantics. If you want to be taken seriously in a gun debate, don’t throw around terms that automatically label you as someone who doesn’t know what the fuck they are talking about
