The law requires you to surrender them to a police dept, dispose or modify them Police are exempt from the law and surrendering them to a department will undoubtedly only enhance their personal collection. Bristol is not doing a buyback and I'm unaware of any departments carrying out such a thing. Sadly this poster is SOL, if they don't like the laws the only option is to vote out the people who forced this law through. My recommendation is sell the firearm and sell your magazines to people out of this state.
