Spall & Fragmentation Containment in a single pouch.

The AR500 Armor® Spall & Fragmentation Shield mitigates and captures spall & fragments created from a bullet impacting the strike face of body armor. This issue is present on some body armor, including body armor which utilizes steel as the ballistic core and has not been treated or coating to contain fragmentation and spall.
