By law, each pull of a semiautomatic rifle’s trigger may only fire a single bullet. With the latest firearm from Slide Fire, however, shooters can potentially spray thousands of bullets rapidly thanks to a loophole in current regulation.
The Bureau of Alcohol, Tobacco, Firearms and Explosives only sets guidelines for the design of a gun’s receiver, which is the part with a serial number.
Slide Fire has skirted the rules by modifying the trigger and stock of the weapon — but not the reciver — so that the gun’s own recoil sets off the next round even without the shooter pressing the trigger again. Techincally, it's still a semiautomatic rifle, even if it doesn't behave like one.
The result is a belt-fed rifle that can shoot up to 800 rounds per minute, on par with an automatic machine gun that is illegal for most Americans to own.
Slide Fire sales and marketing manager Brandon Renner told CNN, "It sprays like a fire hose. We recommend no more than 30 rounds on the belt, but one person could make it as big as they want."
The ATF has been aware of the “bump stock” since 2010, and stated on their website that the device was “not regulated as a firearm under the Gun Control Act or the National Firearms act.”
An ATF spokesperson told CNN, “I can confirm that ATF did approve the device referenced in the letter and that the Slide Fire is legal.”
The SFS BFR rifle is slated to hit stores this fall, and comes with a price tag of $6,000. The company already sells the modified stock that increases firing rate for just a few hundred dollars. However, only the new weapon will use a belt instead of a magazine, greatly increasing bullet capacity.
