Two groups representing firearms manufacturers and retailers are calling for a review of regulations allowing the sale of "bump stocks," which were used in the Oct. 1 Las Vegas mass shooting that left 58 people dead.

Bump stocks are devices attached to semi-automatic weapons that use the recoil of gunshots to generate a rate of fire approaching that of fully automatic weapons. Twelve firearms used by the Las Vegas shooter were equipped with bump stocks, CNN reported.

The National Shooting Sports Foundation and the Sporting Arms and Ammunition Manufacturers' Institute issued a joint statement Monday urging the Bureau of Alcohol, Tobacco, Firearms and Explosives to enforce existing firearms regulations—a rebuke to gun control advocates seeking new regulations.

However, both groups also urged the ATF to review whether bump stocks violate existing law preventing the conversion of semi-automatic firearms into automatic weapons. U.S. residents are only allowed to own fully automatic weapons under certain conditions.

"We urge Congress to allow ATF to complete its review before considering any legislation so that any policy decisions can be informed by the facts and ATF's analysis," the groups said.

NSSF and SAAMI are separate organizations but they share the same administrative staff and headquarters in Newtown, Conn. The National Rifle Association also has called for a review of bump stocks but opposes an outright ban of the devices. http://bit.ly/2yXoMGV
