Last year...
Citadel Gun & Safe lost their FFL due to conducting illegal firearm transactions (selling to prohibited persons).

They continue to be in business by selling safes, firearm accessories, ammunition and surplus items.

The USAF OSI (Office of Special Investigations), FBI, BATFE and LVMPD raided Citadel Gun & Safe.
The owner and several employees were taken into custody and several items were confiscated.

It appears Citadel Gun & Safe was selling stolen USAF equipment.
