Spartan Armor AR500 Level III steel plates at Civil TAC provide a proven steel armor solution for shooters who want reliable rifle protection, multi hit durability, and cost efficient service life. Built from lab certified AR500 ballistic steel, these plates are engineered for Level III rifle protection under the NIJ Standard 0101.06 performance framework when used as intended and paired with an appropriate carrier system. Spartan Armor Systems

These Spartan Armor AR500 Level III steel plates feature an advanced triple curve profile, often referred to as ATC, designed to follow the natural shape of the chest and torso. Instead of a flat or single curve plate that can dig into the chest and resist movement, the triple curve contour wraps more comfortably against the body and spreads weight across a larger contact area. This leads to improved comfort during extended wear, better breathing freedom, and more natural rifle shouldering positions under realistic training and duty use.

Full coat spall mitigation is applied to each plate, covering the strike face and perimeter edges with a specialized polymer encapsulation. When a projectile impacts hardened steel, fragments can be produced as both the bullet and the steel surface deform. The full coat spall mitigation treatment is designed to trap and slow many of these fragments, helping to reduce secondary injury risk to the neck, upper arms, and surrounding areas. The coating also supports corrosion resistance and reduces direct abrasion between the plate and your carrier’s internal fabric surfaces.

As an AR500 Level III steel solution, these plates are built to withstand repeated impacts within their rated threat profile without structural failure. This multi hit durability is one of the primary advantages of steel armor. Where ceramic or composite plates may fracture or lose coverage after one or more hits in the same region, AR500 steel plates maintain their shape and ballistic coverage. This makes Spartan Armor AR500 Level III steel plates particularly well suited for training classes, range work, vehicle kits, and long term readiness roles where armor may see repeated handling and occasional impact testing.

The advanced triple curve geometry greatly improves wearability compared to flat steel options. The curvature supports more natural torso movement when bending, kneeling, or running, and also helps keep the plate seated properly inside the carrier. Less shifting and less edge pressure means the user is more likely to keep the armor on for the full duration of training days or shifts, which is critical for real protective benefit.

These plates are offered in both 10×12 and 11×14 shooter cut sizes. The 10×12 plate is the most common choice, offering a strong balance between coverage and mobility and fitting a wide range of plate carrier platforms. The 11×14 plate increases protective coverage area across the torso and is often preferred by larger framed users or missions where additional coverage is prioritized. Both sizes are compatible with standard shooter cut plate carriers designed to accept steel plates of the corresponding dimensions.

While steel armor is heavier than ceramic and hybrid composite options, many users value the durability, multi hit rating, and budget efficiency of AR500 steel. The triple curve design helps offset some of the perceived weight by improving balance on the chest and reducing concentrated pressure points. When combined with a quality plate carrier and optional trauma pads, these Spartan Armor AR500 Level III steel plates can provide a very usable and dependable armor system for many mission profiles.

Ballistic performance is referenced to NIJ Level III rifle threat protection and guided by the official National Institute of Justice ballistic resistance standard for body armor, NIJ Standard 0101.06, which establishes test conditions and performance thresholds for body armor systems:

Spartan Armor AR500 Level III steel plates are well suited for firearms instructors, range staff, responsible citizens building preparedness kits, law enforcement training rigs, and shooters who want a durable, multi hit steel plate with improved ergonomics and full coat spall mitigation. When combined with an appropriate carrier, sling setup, and support gear, these plates provide a stable platform for rifle training, qualifications, and defensive readiness.

Spartan Armor AR500 Level III steel plates with advanced triple curve and full coat spall mitigation deliver hardened rifle rated protection, enhanced comfort, and multi hit durability in both 10×12 and 11×14 shooter cut sizes, ready to integrate into a modern plate carrier system.
