A Miami Beach man says he is not guilty of defrauding the Pentagon under a contract he had to supply ammunition to forces in Afghanistan.

Twenty-two-year-old Efraim Diveroli entered the plea Monday in Miami federal court. Diveroli remains free on bail.

Prosecutors say Diveroli’s company, AEY Inc., provided banned Chinese-made ammunition to forces in Afghanistan and claimed it came from Albania.

AEY was paid more than $10 million for the ammunition. Prosecutors contend Diveroli’s company removed markings from containers to hide their origin.

No trial date has been set. Diveroli potentially faces decades in prison if convicted of all 71 counts. His attorney has said the Pentagon misconstrued the law and knew the source of the ammunition.
