MERCEDES – A Rio Grande Valley man was arrested Friday for his alleged involvement in smuggling ammunition.

He picked up about 5,000 rounds of ammunition to transport it to a Brownsville storage unit, according to Bureau of Alcohol, Tobacco, Firearms and Explosives agents.

The federal criminal complaint states the man said he knew someone else was going to pick it up and take it into Mexico.

Bryan Guerra of Lone Star Guns explains the ammunition found is one of the most popular types of ammunition because it is used in the SKS rifle and the AK-47 rifle.

"It's 100% legal to buy bulk ammo. There's no restriction on the amount of ammo that you can purchase, as per the federal government," he says. 

KRGV’s Valerie Gonzalez has the details on the arrest.
