I think bump stock and other items that make semiautomatic weapons into automatic weapons should not be made or sold period. I also believe that there should be a limit to how many guns one person should be able to own. I’m not saying that you can’t own but what one person needs 10 semiautomatic rifles to defend their home. How many people are they defending against? If it takes that many then they are a bad shot to begin with. Adding more guns doesn’t make you efficient.
