Spartan AR550 NIJ Certified Body Armor and Sentinel Plate Carrier Package

Spartan Armor Systems AR550 Level III+ Armor NIJ Certified with Spartan Sentinel Plate Carrier

Package includes both front and back AR550 shooters cut steel armor plates with a single curve, with full coat of Encapsuloc™ anti-fragmentation coating, two 6x6 side plates (base coat) and Spartan Sentinel Plate Carrier.

Why Are Your AR550 Single Curve Full Coat Plates Labeled as Level III? 

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+. Quite simply, the NIJ requires that we label AR550 single curve full coat plates as level III even though they are capable of higher ballistic protection.

We’ve taken our Level III Body Armor to a NEW level! Spartan Armor Systems™ is pleased to introduce our AR550 Body Armor!  With a 10% increase in ballistic core hardness, our level III+ AR550 armor defeats higher velocity threats such as XM193, M855, and M80! We’re special rifle threat validated!

Our AR550 body armor is NIJ level III rated but has undergone special threat testing to achieve a level III+ rating, click here to learn more. 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. With a core hardness of approximately 545-560 BHN, we have found our  ballistically rated variant of AR550 that we use is perfect for defeating higher velocity threats, while not exposing the armor plate to extreme stress due to forming.

Our AR550 Level III+ armor has our GEN2 lower cut radius. With a 10% increase in core hardness, this ballistic grade steel is much harder than AR500, but not too hard to cause severe stress while forming.

With higher velocity rifle threats commonly present throughout the United States, we’ve developed this AR550 armor to specifically defeat some common threats such as 5.56 x 45 XM193, 5.56 x 45 M855 /SS109 and 7.62 x 51 (.308 Winchester) at a rated velocity of 3,100 fps or less. Additionally, we’ve successfully defeated these threat profiles from Close Quarters Battle (CQB) distances…repeatedly!
