The Spartan Level III+ AR550 Steel Body Armor set delivers rifle-rated ballistic protection using high-hardness AR550 steel plates — a trusted and affordable option for those who need serious defense against high-velocity threats. Built 100% in the USA, this package is a reliable upgrade for law enforcement, security professionals, or civilians preparing for the unexpected.
Each plate is made from 1/4" thick, laboratory-certified AR550 ballistic steel, engineered to stop a wide range of armor-piercing and high-velocity rounds, including 5.56 XM193, M855 Green Tip, SS109, and 7.62x51mm (.308) at velocities up to 3,100 fps. These Level III+ steel plates exceed standard Level III requirements, giving you an extra edge in life-threatening situations.
Backed by a 25-year shelf life and superior resistance to drops, moisture, and environmental abuse, steel body armor is one of the most durable ballistic protection solutions on the market. Whether you're building your first loadout or upgrading an existing rig, Spartan's Level III+ AR550 armor offers battle-ready protection at a practical price.
