AR500 Armor Level III+ Body Armor plates offer the highest level of NIJ III+ protection in AR500’s line-up.  ASC Level III+ plates are the Second Generation of Level III+ technology.  They provide stand-alone and multi-hit protection from the most common rifle threats (5.56×45 M193, 5.56×45 M855 / SS109 at a velocity up to 3,100 feet per second, and 7.62×51 M80 Ball (.308 Winchester) non-Armor Piercing at velocities up to 3,000 feet per second, and 7.62×51 Armor Piercing (AP Black Tip) rounds up to 2,800 feet per second, and all lesser rifle, pistol, and shotgun threats.  The 10″ x 12″ Back Plate has the same ballistic protection as the Advanced Shooters Cut (ASC) version with the benefit of increased coverage.  This square back plate is designed for use in the back side of a plate carrier.  For ergonomics and comfort, the ASC or other tapered plate may be more suitable for arm movement if you’re looking for a plate for the front pocket of the carrier.  Please note that your plate carrier must be compatible with a rectangular back plate cut.  A list of compatible carriers can be found below.

AR500 Armor uses a ballistic grade steel core that’s maintenance free and only .26″ thick.  Standard plates come pretreated with a PAXCON (Line-X) coating which increases the plate’s ability to protect against ammunition spall and fragmentation.  The treated steel core is stress fracture resistant, giving it an extreme advantage over ceramic, Dyneema, UHMWPE, and other armor that can fail if dropped or exposed to impacts.  The protective coating also provides a fully sealed design that’s impervious to liquids, chemicals, and harsh elements.  Customers also have the option of upgrading to a PAXON (Line-X Build Up) coating.  The Build Up coating further reduces spall and fragmentation by absorbing more of the bullet material into the outer shell of the plate, instead of deflecting it.  A standard plate weighs only 8.5 lbs.  The Build Up coating adds another .4 lbs and up to a total thickness of .48″.  Please note that because of demand, choosing a Build Up coating can add up to several more weeks of expected delivery time for your order.

Before your final purchase, you’ll also want to decide if you’d like to add a trauma pad for your plate.  Trauma pads are constructed of a non-Newtonian material and are designed for the sole purpose of reducing the amount of blunt force energy felt by the armor user.  They offer no additional ballistic protection and add about 5.9 oz and .25″ in thickness to your plate carrier.

Carrier Compatibility: Compatible with the AR500 XL, Testudo™ Gen 2, Concealment, Operator II®, Emergency Personal Carrier (EPC), and ESCORT.
