The funny thing I see is that places like Walmart have stopped selling “handgun and assault rifle” ammo. Yet, they still sell .308… which is a significantly more powerful round than .223/5.56 (most common AR round), because it’s for “hunting rifles.”

There are AR-platform rifles that shoot .308, just as there are semiautomatic hunting rifles. All they’re doing is trying to place a label on something due to how it is perceived to those unfamiliar with firearms. It’s really just splitting hairs, and broad definitions can lead to slippery slopes.
