Federal authorities say illegal Glock "switches" have become one of the fastest-growing firearm threats in America, with recoveries of the tiny machine gun conversion devices soaring 784% nationwide in the last four years.
That national trend came into sharp focus not far beyond Wyoming’s eastern border this week when a monthslong western Nebraska investigation ended with seven arrests.
Investigators allegedly found Instagram photos and videos showing young men posing with — and in one case firing — Glock-style pistols equipped with the illegal devices, which modify semiautomatic handguns into fully automatic machine guns.
The investigation culminated Wednesday morning when SWAT teams and dozens of officers served search and arrest warrants across Scottsbluff, Gering and Bayard, Nebraska. By the end of the operation, seven people — two adults and five juveniles — were in custody.
Authorities report that the Western Nebraska Intelligence & Narcotics Group (WING) began investigating after receiving information that adults and juveniles were allegedly involved in drug trafficking while possessing the modified fully automatic firearms.
Instagram Trail
Court records show law enforcement soon turned to social media.
Investigators secured a warrant for an Instagram account they believed belonged to Preston Torres, who is one of the adults arrested Wednesday.
When Meta returned the account records, deputies say they found multiple photos and videos allegedly showing Torres holding and firing a Glock-style handgun equipped with an illegal switch.
A second affidavit says investigators later searched another Instagram account and found a photograph showing Rochne Gukeisen, the other adult arrested, holding a similarly modified Glock pistol.
The affidavit says the photo showed Gukeisen pointing the handgun at Torres, who deputies had already identified in other social media posts.
Investigators wrote that based on their training and experience, the visible conversion devices transformed the pistols into machine guns under Nebraska law.
Gang Allegation
Investigators also asked a judge to temporarily seal the arrest warrants until they could be served, writing that both men were known members of the 308 BOYZ gang and that keeping the warrants confidential was necessary to safely apprehend them.
Authorities arrested 18-year-old Torres-Isles and 19-year-old Gukeisen, each on suspicion of possessing a machine gun.
They also arrested five juveniles — three 17-year-olds, a 16-year-old and a 15-year-old.
Scottsbluff County Attorney Dave Eubanks said three of the juveniles also are accused of possessing machine guns, while two face allegations of distributing cocaine.
Sheriff Mark Overman told Cowboy State Daily the investigation remains active and declined to discuss additional evidence or whether more arrests are possible.
Tiny Device, Big Threat
Although ATF was not involved in the Nebraska investigation, agency spokesperson Ashlee Sherrill said it has documented a dramatic rise in machine gun conversion devices nationwide.
Known as Glock switches or auto sears, the parts are small enough to fit in the palm of a hand. But once installed, they can allow a semiautomatic pistol to fire continuously with a single pull of the trigger.
Under federal law, the devices themselves are legally considered machine guns, even if they have not been attached to a firearm.
"They present a significant public safety concern," Sherrill said, because they allow handguns to fire at rates comparable to fully automatic weapons, dramatically increasing the danger to people and responding officers.
According to ATF, recoveries of suspected machine gun conversion devices traced by the agency increased from 658 in 2019 to 5,816 in 2023.
As the devices have become more common, Sherrill said ATF has expanded training for federal, state and local law enforcement agencies to help officers identify the devices, understand trafficking trends and properly recover and trace them.
