Spartan Armor Systems™ is pleased to introduce their AR550 Body Armor!  With a 10% increase in ballistic core hardness, level III+ AR550 armor defeats higher velocity threats such as XM193, M855, and 7.62x51mm M80 with other special rifle threats validated! 

Spartan Armor Systems AR550 body armor is NIJ level III rated, but has undergone special threat testing to achieve a level III+ rating.  NIJ Certification applies to AR550 Shooters and Swimmers Cut Single Curve Full Coat armor plates. 



Spartan Armor Systems AR550 armor hits the “sweet spot” in the Brinnell Hardness (BHN) range. With a core hardness of approximately 545-560 BHN, ballistically rated AR550 is perfect for defeating higher velocity threats while not exposing the armor plate to extreme stress due to forming.

Spartan Armor Systems AR550 body armor now has the option of Advanced Triple Curve (ATC) - an industry FIRST! Spartan Armor Systems™ is proud to be the FIRST in the industry to commercially offer triple-curved AR550 body armor. With higher velocity rifle threats commonly present throughout the United States, they 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, they've successfully defeated these threat profiles from Close Quarters Battle (CQB) distances…repeatedly!

This armor comes as a pair, meaning you will receive both front and back plates.

Weight (per plate):   

  • 8x10 AR550 Shooters Cut: Base Coat 5lbs 5oz. Full Coat 6lbs 1oz.
  • 10x12 AR550 Shooters Cut: Base Coat 8lbs 1oz. Full Coat 8lbs 10oz.
  • 11x14 AR550 Shooters Cut: Base Coat 9lbs 15oz. Full Coat 11lbs.

Full Coat or Base Coat Options: 

The Base Coat option has a thin layer of coating to aesthetically enhance the plates, and to provide corrosion resistance. This coating has minimal, if any, fragmentation mitigation capabilities.

The Full Coat option provides the front of the plate with a lining of 1/4-3/8" of their proprietary Encapsaloc™ fragmentation mitigation coating.  The result is a plate approximately 1/2-5/8” total thickness.

Thickness:   .25″ AR550 plus approximately .25″ coating makes this slim profile plate overall .5-.6″ in total thickness
