GOP and NRA turn on the bump stock: the politics and mechanics of gun modifications

In the wake of the shooting in Vegas, congressional Republicans said Wednesday they’d consider banning the bump stock – the attachment used by the gunman in Vegas, which allows semiautomatic rifles to fire more quickly.

The NRA followed suit, calling for a federal review of the modification and suggesting that further regulations on bump stocks might be needed, though lobbying group Gun Owners of America has continued to oppose the ban.

In addition to the shifting politics over the gun modification conversation, we’ll also take a closer look at the modifications themselves. Is there a legitimate use of the trigger crank and the bump stock for gun owners? If these modifications are taken off the market, is there a black market that fills the gap? Are there other unregulated gun attachments that effectively turn semiautomatics into automatic weapons?
