Whatever your threat protection needs, Smith Defense is proud to offer top-tier protection to first responders and civilians.
Made from ballistic-grade steel, Level III+ AR550 Steel Core Armor has a Brinell ballistic core hardness that’s a full 10% greater than AR500 steel armor for added protection against high-velocity rifle rounds. Although Level III+ isn’t an official NIJ rating, it indicates the steel has been independently tested and found to exceed Level III standards.
Known for durability, AR550 plates stop AR15 rounds, all handgun calibers up to .357 Magnum and other high-caliber rounds. Level III+ steel armor is less bulky than ceramic armor, and there’s very little or no backface deformation when struck, which significantly reduces the chance of serious injury. You can also wear a trauma pad, which will add additional protection and reduce back face deformation (BFD).
Our AR550 III+ steel plate comes in shooters cut and Small Arms Protective Insert (SAPI) cut, each of which is available in various sizes. Actual plate dimensions vary, depending on the plate’s cut and size. Each is coated with premium armor finishing to prevent rusting and spalling injuries.
Level III+ AR550 plates will stop rounds of up to .30 caliber M2 armor-piercing ammunition. They’re worn when high-velocity rifle fire is likely to be encountered. AR550 steel armor is frequently used by the military, first responders and law enforcement agencies, including SWAT teams, to ensure they get “there and back” safely.
