In March, the state of Connecticut Supreme Court ruled that Remington could be sued by victims’ families for how the company marketed the assault-style weapon a gunman used to kill 20 Sandy Hook schoolchildren.
Remington, joined by a number of gun rights activists, had argued that federal law protects weapons manufacturers from being sued over gun crimes.
A lone gunman armed with a Remington assault rifle opened fire on children at Sandy Hook school in Connecticut in December 2012, killing 20 children and six staff before killing himself.
The lawsuit comes amid a spate of mass shootings in the United States, many using military-style assault rifles, such as the 2017 massacre at a concert in the city of Las Vegas that killed 58 and wounded hundreds.
