A major border bust near Nogales ended with federal agents seizing more than 47,000 rounds of ammunition headed for Mexico this month, according to authorities. The bulk of the haul was 7.62×39 cartridges, the go-to ammo for AK-47-style rifles.
How Agents Intercepted The Shipment
During an outbound inspection, the Nogales Contraband Enforcement Team uncovered 18 cardboard boxes packed with roughly 25,000 7.62×39 rounds, according to KTSM. Follow-up searches by a federal task force pushed the total number of seized rounds past 47,000, with about 90 percent of the ammunition made up of 7.62×39 shells, the outlet reported. Officials credited the bust to coordinated outbound enforcement at ports of entry across southern Arizona.
Operation Southbound And The Law Enforcement Push
The seizures are part of a U.S. Customs and Border Protection outbound initiative known as Operation Southbound, KTSM reported. Successful interdictions and seizures play a critical role in protecting Americas borders and national security by preventing illegal weapons reaching dangerous criminal networks, Guadalupe Ramirez said, according to the outlet. KTSM also highlighted other February finds in Nogales, including about 4,000 .22-caliber rounds on Feb. 13 and roughly 18,000 cartridges hidden in a false compartment on Feb. 24.
Why This Caliber Raises Red Flags
Seven-point-six-two-by-thirty-nine ammunition is standard for AK-style rifles and is valued by organized-crime groups for its availability and stopping power. Investigations into cross-border gunrunning have shown that bulk shipments of this caliber can sharply increase cartel firepower and complicate efforts to curb violence. The ICIJ has documented similar trends in recent reporting, which helps explain why outbound inspections zero in on boxes, hidden compartments and commercial cargo at busy ports of entry.
What Comes Next On The Border
Authorities say outbound enforcement by CBP and federal partners will keep ramping up as part of broader efforts to disrupt arms trafficking along the Arizona border. The latest seizures highlight how tough it is to police high-volume commercial traffic and how much damage heavily armed groups in Mexico can inflict when even a fraction of these shipments slip through.
