Hence why it is a Bill of Rights not Bill of Needs. All guns are designed to kill. The only legally defined part of a gun is the action. My hunting rifle has a semiautomatic action. It fires one shot per trigger pull, just like an AR15. There are even after market (for the range not for hunting) 10 round magazines. Being 30-06 instead of .223 makes my rifle a much more powerful weapon on a shot per shot basis. Should it be banned?
Magazine limits are a joke. A somewhat competent shooter loses 4 seconds at most total firing 30 rounds from 1 magazine as 10 each from 3. Especially since they don't have full automatic capacity, they are walking and shooting.
Other than that we are talking about bans on cosmetic features. Nothing that actually makes a gun more dangerous.
