AR500 Armor Level III Body Armor is manufactured from an extremely rugged ballistic grade steel core and coated with PAXCON (a division of Line-X) spall and fragmentation protective coating. These ballistic steel plates are unmatched in the industry and is formulated and treated specifically to AR500's exacting specifications for improved consistency and durability before being tested to NIJ standards. AR500's ballstic plate cores are stress fracture resistant and feature an ultra-low profile of just 1/4", ideally designed for the extreme abuse of day-to-day use, training, and less than ideal storage conditions. AR500 Armor body armor will outlast alternative solutions such as Ceramic, Dyneema, UHMWPE, and raw / uncoated steel trauma plates! The Curved Level III ASC Trauma Plates feature an asymmetric cut that allows for proper coverage of your vitals, while making shouldering and firing your rifle with your strong hand easier, faster, and more comfortable.
