Yes, but start with a voluntary buyback and ban on purchasing assault weapons before enforcing a mandatory buyback

This is a infrigment on the second amendment that should never be allowed. rifles are necessary to defend your family and homes in the event of a robbery, if someone is already breaking the law by robbing my house what makes you think they will follow the law about not owning a rifle? If I am a law abiding citizens and dont posess a rifle and a robber does I will have less magazine capacity less stoping power which will leave a higher likelyhood to my family being injured or possibly killed. majority of mass shooting are commited by hanguns not rifles the only reason you want to ban rifles is cause they look scary.
