A Texas retailer of now-banned bump stocks has transferred about 60,000 of the gun-related items to the federal government to be destroyed.

RW Arms of Fort Worth turned over the bump stocks to the Bureau of Alcohol, Tobacco, Firearms and Explosives for shredding and recycling.

ATF agents were present Tuesday, when the ban took effect, as crates of new RW Arms bump stops were delivered to a shredding facility.

The ban, supported by the Trump administration, follows the October 2017 Las Vegas Massacre where a gunman used bump stocks to fatally shoot 58 people at an outdoor concert.

Bump stocks make semi-automatic weapons fire rapidly. The U.S. government isn't allowing existing owners to keep their bump stocks. The items must be destroyed or surrendered to authorities.
