Whether the government is going to come take us or our guns away 1 by 1 is irrelevant to an extent in my view point. If it does happen, it'd be nice to have some heavier firepower than a bolt action rifle with a 5 round inner magazine offers. However, mostly I'd just want one because it'd be fun as hell to go shoot on the weekends. If they make 30 round mags for it, sure load it up with some rounds and go fuck up some cans in your woods/backyard or at a firing range. My car goes way fast if I want it to, way faster than I need to just get to work or whatever. My guitar amp can get WAY louder than I need for playing guitar in my room. Does that mean I'm not entitled to have these luxuries if I want them?
