The BlueStone Level 3A Special Threat Ballistic Armor Plate helps give extra protection to Law Enforcement and Military that need it, while minimizing the discomfort other armor can have. This ballistic armor plate is only 1/4 inch thick and weighs just 1 pound, but it still defeats all handgun rounds. The armor easily inserts into BlueStone custom load bearing vest carriers to position it near the center of your chest. The plates also work great inside of BlueStone Grab and Go Carriers, so you can easily have protection in reach. This 10" tall x 12" wide ballistic armor plate is NIJ 0101.08 and is built to last. The world is a dangerous place - be ready for any situation.
