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 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 perfectly hits the “sweet spot”. It’s much harder than AR500, but not too hard to cause severe stress while forming.
 
Our AR550 Spartan 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, 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!
