Several families affected by the Uvalde school shooting are targeting the maker of the murder weapon for legal action. But experts say a lawsuit is a longshot, thanks to federal laws.

For example, in a case involving the Sandy Hook shooting, the firearms manufacturer Remington settled for about $72-million.
