Spartan Armor AR550 Level III+ Steel Body Armor Plate Achilles Package

***Estimated Delivery: 2-4 weeks

The Spartan Armor Systems AR550 Level III+ Achilles Package pairs two AR550 steel body armor plates in 10" x 12" Shooters Cut with the Achilles Laser Cut Plate Carrier in a single ready-to-wear bundle. The AR550 steel is made from American steel and manufactured entirely in the USA, delivering Special Threat Rated Level III+ rifle protection at a price point well below comparable rifle-rated setups. The Base Coat plate weighs 8 lbs 1 oz and measures 0.25" thick; the Full Coat variant weighs 8 lbs 10 oz and measures 0.5" thick. A 5-year warranty against manufacturer defects covers both the plates and the carrier. Optional AR550 side plates are available as an add-on through the variant selector.

Who this is for

  • Law enforcement and security professionals who need rifle-rated threat protection in a full carrier system without sourcing plates and carrier separately.
  • Military personnel and veterans building a training or duty setup around a proven American-made steel plate at a controlled cost.
  • Responsible civilian preppers and range shooters who want a complete, adjustable plate carrier package that ships ready to wear from size S through 4XL.

Ballistic performance

AR550 is a hardened American steel alloy engineered specifically for body armor applications. The Special Threat Rated Level III+ designation means these plates go beyond the standard NIJ 0101.06 Level III threat matrix and are rated to defeat the higher-velocity and penetrator-core rounds that defeat standard Level III steel. That includes common rifle threats encountered across law enforcement and civilian defensive contexts.

Two coating options are available. The Base Coat is 0.25" thick and weighs 8 lbs 1 oz per plate. The Full Coat is 0.5" thick (12.7–15.2 mm) and weighs 8 lbs 10 oz per plate. The Full Coat's additional encapsulation significantly reduces fragmentation risks by containing spall that would otherwise project outward on bullet impact. Specifications for Single Curve and Advanced Triple Curve (ATC) geometry are identical across both coating levels.

Plate compatibility and cut geometry

The Achilles Package ships with 10" x 12" Shooters Cut plates as standard. Shooters Cut trims the upper corners of the plate to open up arm range of motion compared to a square-cornered plate, making it the most common choice for active-use carriers. The Achilles carrier itself accepts 10" x 12", 11" x 14", and 9.5" x 12.5" Medium ESAPI plates, so the plates included in this package fit the carrier natively, and you retain the option to swap to a different size later. The carrier additionally accommodates 6" x 6", 6" x 8", and 5" x 11" side plates — available as an add-on at checkout. Note that side plates shown in product images are not included with the base package.

Achilles Laser Cut Plate Carrier

The Achilles carrier is built from 1000-denier polyester with laser-cut MOLLE webbing across the front, rear, and cummerbund panels. Laser-cut MOLLE eliminates the bulk and weight of sewn-on PALS rows, keeping the profile slimmer while retaining full accessory attachment compatibility. The carrier runs from size Small through 4XL with a fully adjustable and removable cummerbund and an adjustable internal buckle system for dialing in fit across a wide range of torso lengths and chest circumferences.

Comfort features include padded shoulder straps, padded front and rear panels with ventilation vents, and a rear drag handle. A removable triple M4 mag pouch comes pre-installed on the front panel, and a YKK-zippered admin pouch provides secure storage for documents, tools, or electronics. YKK zippers are the hardware-industry standard for reliability under sustained field use.

Frequently asked questions

What is Special Threat Rated Level III+ and how does it differ from standard Level III?

Standard NIJ 0101.06 Level III covers six-shot testing against .308 Winchester FMJ at 2,780 fps. Special Threat Rated Level III+ is a vendor-defined designation for plates that exceed that baseline and are rated against higher-velocity and penetrator-core rifle rounds that defeat standard Level III steel. It is not a separate NIJ certification tier but indicates tested performance beyond the published NIJ Level III threat matrix.

What is the difference between Base Coat and Full Coat AR550?

Both coat levels use the same AR550 steel core. The Base Coat adds a thin protective finish and measures 0.25" thick at 8 lbs 1 oz. The Full Coat encapsulates the plate in a thicker layer that significantly reduces fragmentation risks by containing spall on impact. The Full Coat measures 0.5" thick and weighs 8 lbs 10 oz. If spall mitigation is a priority, choose Full Coat.

What is the difference between Single Curve and Advanced Triple Curve (ATC)?

Single Curve plates bow along one axis to follow the natural contour of the chest. Advanced Triple Curve plates conform along three axes, wrapping more closely to the body for improved contact, comfort, and blunt-force trauma distribution. Weight and thickness specifications are identical between the two geometry options for the AR550. ATC is the preferred choice for extended wear.

Do the side plates shown in the product images come with this package?

No. Side plates shown in product images are not included with the Achilles Package. AR550 steel side plates in 6" x 6", 6" x 8", and 5" x 11" sizes are available as an add-on through the variant selector on this page. The Achilles carrier has dedicated pockets for all three side plate sizes.

Does this package come with plates, or is the carrier sold separately?

Yes, this package includes two AR550 Level III+ 10" x 12" Shooters Cut plates and the Achilles Laser Cut Plate Carrier. Everything ships together as a ready-to-wear bundle. You select coating level (Base Coat or Full Coat) and plate curve (Single Curve or ATC) through the variant options before adding to cart.

Can this package be shipped to my state?

This package cannot be shipped to New York or Connecticut due to state body armor restrictions. It is subject to US export regulations. Under 18 U.S.C. § 931, anyone with a federal felony conviction for a crime of violence is prohibited from purchasing or possessing body armor.

The Bulletproof Zone Promise

When you buy body armor, you're buying your safety. We don't take that lightly. Here's what every order from Bulletproof Zone includes.

1. Authorized dealer of every brand we carry

Every plate, vest, and carrier we ship comes from the manufacturer directly to our warehouse. We don't sell gray-market product, surplus, or returns. That means factory-fresh stock, the full manufacturer warranty, and real after-sale support — the kind only an authorized dealer can offer.

We maintain authorized-dealer relationships with America's leading body armor brands, including Spartan Armor Systems, AR500 Armor, RMA Defense, Shellback Tactical, Caliber Armor, DFNDR Armor, Protection Group Denmark, BulletSafe, BulletBlocker, and over 40 more.

2. Best price, guaranteed

If you find a lower price at another authorized dealer of the same product within six months of your purchase, we'll refund the difference.

Why the "authorized dealer" requirement? Because gray-market and surplus armor may not be genuine, may have a compromised supply chain, and almost never comes with a manufacturer warranty. We won't price-match against products that may not actually protect you.

3. Free fitment consultation

Body armor only protects you if it fits. Email us a photo and your measurements before you order, and one of our specialists will help you size your carrier and plates correctly — at no charge, no obligation.

4. Trusted by thousands of customers

Bulletproof Zone has been a trusted authorized dealer of America's leading body armor manufacturers for over five years. We have over 4,000 verified Trustpilot reviews from real customers across all 50 states.

Price Match Guarantee — Terms

  • You must have purchased the item from our website before requesting the price match.
  • Discounted items and "free with purchase" items are not eligible.
  • The item must be in stock on the competitor's website at the time of your request.
  • The price match is valid for six months from the date of your purchase.
  • The competitor must be an authorized dealer of the product. Auction sites (eBay, Overstock), discounters, and gray-market resellers do not qualify.
  • The competitor must operate an online store. Brick-and-mortar-only retailers do not qualify.
  • Price match applies to the item price plus shipping. Sales tax is excluded.

To request a price match, email us a link to the product on our site and the same product on the competitor's site within six months of purchase. We'll process the refund.

The spartan system that I chose and received was better than expected ....free of damage or manufacturer error. AR550 is heavy but exactly what I needed due to its low profile and ballistic performance. It is very easy to move my torso and arms due to this low profile.....so, less fatigue while wearing....and moving. I rate this off of military body armor that I wore while serving....Spartan is superior to the military contract companies that I have worn armor from in the past. Great product. Be sure if you are wearing it to start working out in it eventually....if you dont already know....you will eventually. Regardless, Have A Good One.
