This video compares AR500 steel and ceramic composite ballistic plates. Steel plates (NIJ Level 3) are durable and handle multiple hits but are heavy and pose a spalling risk. Ceramic plates (NIJ Level 4) are lighter and stop higher velocity rounds but are fragile and vulnerable to repeated impacts in the same area. The choice depends on threat profile and weight needs.
Premier Body Armor's 5mm Level 3 steel core plates demonstrated exceptional durability, withstanding approximately 78 rifle rounds from 7.62x39mm, .308 Winchester, and 5.56 M855 Green Tip without penetration. Despite significant impacts, including multiple mag dumps, the plates only showed minor denting and coating damage, exceeding their rated capacity.
