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.
Premium AR550 Steel: Manufactured from 1/4" thick, laboratory-certified AR550 ballistic-grade steel, these plates offer exceptional hardness and strength, effectively stopping higher velocity rounds such as 5.56 XM193/M855 (Green Tip)/SS109, and 7.62x51mm (.308 Winchester) at velocities up to 3,100 fps.
Advanced Curvature: The Advanced Triple Curve (ATC) design offers one of the most ergonomic steel plate fits available. The contour hugs the torso and shoulders naturally, allowing for better mobility and less fatigue during extended wear.
Encapsaloc™ Spall Mitigation Coating: Each plate is available with Spartan Armor Systems' proprietary Encapsaloc™ coating, designed to effectively trap and mitigate bullet fragmentation upon impact, thereby reducing the risk of injury from spall.
American Durability: Made 100% in America, with a 25-year shelf life and resistance to environmental factors, these plates are built to withstand rigorous use over time. Steel plates are less susceptible to damage from drops or rough handling, ensuring consistent performance.
