SPARTAN ARMOR SYSTEMS® AR550 BODY ARMOR SWIMMERS CUT SET OF TWO



Product Overview

Spartan Armor Systems® AR550 Body Armor Swimmers Cut body armor is specifically designed to feature a streamlined cut, which reduces overall weight, enhances mobility, comfort, and ergonomics in the field while affording this higher degree of threat protection. As with our other AR550 body armor products, Spartan Armor Systems® AR550 Body Armor Swimmers Cut body armor has literally taken Level III-rated body armor to the next level by adding a 10% increase in ballistic core hardness to their AR550 line of armor. Because of this enhancement, our AR550 level III+ body armor offers operators advanced rifle-rated threat protection and has been special threat validated in an independent NIJ credentialed laboratory. Manufactured and tested within the highest quality standards, utilizing laboratory-certified steel, our single curve, full coat AR550 plates have received NIJ Certification under NIJ 0101.06 level III specifications.

NIJ Certified

Protective Value Added 

We understand the NIJ rating system can be confusing. Simply put, our AR550 body armor is certified as NIJ (National Institute of Justice) level III rated but has undergone special threat testing to achieve a level III+ rating, click here to learn more. 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 that special threat testing was created within 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 AR550 single curve full coat plates are certified as NIJ level III, rest assured they are made from AR550 ballistic grade steel and have been special threat tested to attain the level III+ qualification. Quite simply, the NIJ requires that we label Spartan Armor Systems® AR550 Single Curve Full Coat Plates as “Level III” even though they are capable of providing the operator with a higher degree of ballistic protection. 

 

Battle Hardened

Our AR550 armor hits the “sweet spot” in the Brinell Hardness (BHN) range. With a core hardness of approximately 545-560 BHN, we have found that the ballistically rated variant of AR550 that we use when manufacturing our AR550 armor 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, it’s much harder than AR500, but not so hard that it risks incurring severe stress while undergoing the formation process.

 

Laser Cut to Protect Ballistic Integrity

All steel core body armor is cut and shaped after the ballistic properties have been formulated within the steel. While other steel body armor manufacturers commonly use plasma torch cutting that applies excessive heat (25,000 ˚C / 45,000 ˚F) to a wide portion of the steel plate, Spartan Armor Systems® only utilizes laser cutting in order to protect the ballistic integrity of each steel core body armor plate we manufacture. Plasma cutting also requires grinding to clean up the edges after the fact, resulting in increased heat and possible fatigue. At Spartan Armor Systems®, we maintain the highest production integrity and quality standards every step of the way for our customers because we know what is at stake. 

 

Additional Protection: Full Coat or Base Coat Options

We strongly recommend choosing our full coat option when you buy steel core body armor. Our proprietary plate coating, Encapsaloc™, is a potentially life-saving feature that captures spalling as a result of ballistic impacts on the strike face of the steel core armor plate. Do not settle for steel armor that is merely coated with generic truck bed liner spray coatings that have not been tested for ballistic efficacy. The strike face of our Spartan Armor Systems® AR550 Body Armor plates proudly bears the mark of our Spartan logo.

 IMPORTANT NOTE: The base coat option only provides protection against corrosion and offers little to no fragmentation/spall mitigation. 

 

Blazing The Trail of Innovation

Our AR550 Spartan Body Armor now offers operators the option of coming with the Advanced Triple Curve (ATC) feature. This is an industry FIRST! Spartan Armor Systems®™ is proud to be the LEADER in the industry when it comes to offering our customers 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!

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