A Florida arms dealer convicted in a $300 million Pentagon scheme is pleading guilty to another federal weapons charge.

A plea agreement filed in Orlando federal court shows that 24-year-old Efraim Diveroli of Miami Beach will plead guilty at a hearing Tuesday to firearms possession by a convicted felon.

Prosecutors say Diveroli possessed numerous weapons and tried to broker a deal for thousands of rounds of ammunition and other weapons gear with undercover informants. Diveroli faces a 10-year maximum prison sentence in that case.

Diveroli previously pleaded guilty to conspiring to illegally ship Chinese-made ammunition to Afghan soldiers under a Pentagon contract. He is awaiting sentencing in Miami for that conviction.
