I have never owned a gun and don't plan to but I do believe in the right to own one if you choose too.  Having said that I believe that bump stocks and any accessory used in aiding to modify or enhance the weapon to where you can turn a semi-automatic weapon into a simulated fully automatic weapon is overkill and must be outlawed and no longer sold except directly to law enforcement agencies and the federal government/military.  Same for fully automatic weapons.
