The term "assault rifle" is a typical leftist nomenclature that stems from pure ignorance of guns( aka ,a tool) how they function and ultimate purpose.a civilian ar 15 style rifle does not and can not be modified to full auto just by dropping in a new lower.even a experienced gun smith will tell you its basically impossible.i think most antis are against the magazine capacities.what they dont understand is that .223 or 5.6 is not a particulary powerful round.my .270 deer rifle is way more powerful,velocity and penetration capabilities.to keep this short assault rifle is right up there with the incredibly overused and stupid term "gun violence".more people get killed every year from knives,baseball bats hammers and cars.
