How many rounds can you put through a silencer before it is no longer affective? She is a complete idiot and should keep her mouth shut.
Silencers are easily the least understood thing by the general public when it comes to guns. When congress people say stuff like that, it really makes them sound like total morons.
Reminds me of the guy (Alan Grayson FL congressman) that said the AR in Orlando could shoot off 700 rounds per minute.
