A bump fire stock, also known as a bump stock, is a device that enables semi-automatic rifles to fire more rapidly, similar to automatic weapons. After the massacre, lawmakers first responded by saying they, including House Speaker Paul Ryan , didn't even know what a bump stock was. A spokeswoman for the ATF told CNN on Tuesday that Senate judiciary committee staffers were briefed by the ATF regarding bump stock related matters, but had nothing further to add. If that (bill banning bump stocks) actually gets on the Senate floor, I'd vote for it." The "Closing the Bump Stock Loophole" act would would require that those in "possession of or purchasing bump stock devices ... (undergo) a rigorous background check, fingerprinting and (pay) a $200 registration fee," according to a summary of the bill posted on the website of Pennsylvania Democratic Rep. Brian Fitzpatrick.
