I AM the lesser man, but I can still kill a tyrant's stooge come to kill me with my AR-15. I don't shoot .308 rifles well, because I don't have the upper body strength. But I can shoot the AR-15 very accurately, ringing steel on every round in a magazine at 100 yards.
There are guns for everyone. One size does not fit all.
I’m talking about calibers not guns. Point being if the .223 ammo is regulated, regardless of the platform, it would be reasonable to expect “them” to come after everything bigger.
