Product details:
NIJ Certification applies to AR550 Shooters and Swimmers Cut Single Curve Full Coat armor plates. Note AR550 side plates are NIJ compliant are not NIJ certified. Our AR550 armor hits the "sweet spot" in the Brinnell Hardness (BHN) range. Our AR550 Level III+ armor has our GEN2 lower cut radius. With a 10percent increase in core hardness this ballistic grade steel is much harder than AR500 but not too hard to cause severe stress while forming. Spartan AR550 Single Curve Full Coat body armor plates are labeled as level III on the back of the plate as the National Institute of Justice (NIJ) does not currently have a level III+ rating. Level III+ indicates special threat testing and was created by the body armor industry to fill the void between NIJ 0101.06 level III and NIJ level IV specifically to account for high velocity penetrator rounds such as M855 (aka green tips). While Spartan AR550 single curve full coat plates are certified as NIJ level III rest assured they are made from AR550 ballistic steel and have been special threat tested to level III+.
