RMA’s Level IV (Model #1155sp) 6×6 side plates SET is a cost effective and also multi-hit rated plate that offers superior Level IV protection to the vital organs above your hips. 6″x6″ side armor plates are the most commonly worn accessory plates on the market. Professionally wrapped, water resistant, and also manufactured 100% at RMA’s factory in Centerville, Iowa to defeat rifle rounds up to and including 30.06 M2AP rounds. Side armor plates are designed to provide additional protection to vital organs from ballistic threats and also shrapnel where torso plates do not provide coverage.

RMA is the most sought after brand of armor plates by law enforcement officers in the United States. We’ve proven to be the strongest, top engineered, and also most efficient manufacturer in the country. Nobody else comes close. Owned and operated by a former police officer and also US Marine who has worn armor in two careers and knows what you need.


If you already own a plate carrier, please check with the manufacturer to ensure that your plate carrier also accepts side armor. The Shellback SF Plate Carrier has built-in side armor plate pouches into the cummerbund. The Condor MOPC plate carrier, Shellback Banshee and Banshee 2.0, along with the Crye Precision JPC 1.0 and also 2.0 do not accept side armor on their own. Accordingly, we have three side armor plate pouches you can attach to your carrier. Firstly, the 0331 Tactical Side Armor Pouch. Secondly, the Condor Side Armor Pouch. Lastly, the Shellback Tactical Side Plate Pouch set.

  1. Steven P. (verified owner)

    Hardly noticeable when in kit and to me do not slow me down at all. Weight is what I expect out of side plates. Quality of these plates are excellent. As far as side plates go, yes they are necessary.

  2. Dennis T. (verified owner)

    Very well made.

  3. Calvin (verified owner)

    Great curvature to these plates and fits perfectly in the Defense Mechanisms 6×6 side plate bags. They feel heavy but on the scale, they weigh less than the advertised weight of 2.5 lbs each. I’ll let yall know if I get shot and will update the review.

  4. Patrick Lozito (verified owner)

    I have complete confidence in RMA products. I trust my life to them.

  5. Paul (verified owner)

  10. Jeff Z. (verified owner)

    Perfect, Fit like a Glove

  11. Aaron L. (verified owner)

    Side plates fit perfectly in my Large SDS RBAV. To bad they don’t have a 6″x8″ side plate option.

  12. Trevor (verified owner)

    Lightweight and solid, durable construction. Haven’t been shot while wearing them yet, so I can’t attest to their protection, but I trust RMA’s specs.

  13. Anonymous (verified owner)

    Great quality, perfect fit on the side. Allows for good movement and comfort.

  14. Anonymous (verified owner)

    I chose RMA plates for a contingency set, after watching several videos in which plates that were tested showed minimal back-face deformation, when shot with the rounds that each plate was rated for. Combined with trauma pads, I’m confident that most soft-tissue damage or incapacitation resulting from a strike, would be well mitigated. For this specific price range, I could not find a better alternative, which has received the same amount of public testing, or which has produced the same back-face deformation results.

    Very niceeeeee, I like.

  16. Stefon H. (verified owner)

    Awesome product great quality

  17. Henri (verified owner)

    By far the EXCELLENCE in my Shellback Tactical Elite 3.0 Plate Carrier side pouches. They are comfortable, dont get in the way. Of my Drum Pouches, which are a snug fit. A must have for Professionals!

  18. Anonymous (verified owner)

    Overall purchasing and shipment was phenomenally fast. On the products, first thing’s first, side plates will always be more cumbersome, that’s just the reality of it. RMA plates however comes highly recommended; good curvature, slim construction and light weight and with minimal snag points or hot spots will ensure that you can wear them for an extended period of time without feeling any significant discomfort. Ultimately, the peace of mind of wearing RMA’s products will overshadow all discomfort, you will get used to the minimal extra weight very quickly.

  19. Anonymous (verified owner)

    Make the multicurve plates 4 pounds lighter and level 4+. Do that AND keep your prices around 300-350 a plate and you WILL dominate and be No.1 in the civilian market, without question. I love this company and the products you make. GET IT DONE GENTLEMAN, we need that product!

  21. Pawel (verified owner)

    First of all the order was shipped promptly and discretely. The set Fits nicely into Visim carrier’s built-in side pockets. Thinking about buying more of these or similar inexpensive carriers with different colors and camo patterns.

  22. Shaun (verified owner)

    Plates look great in new condition.

  23. Dakota Maynor (verified owner)

    Pleased with the qaulity.

  24. Aaron G. (verified owner)

    Using a competitors steel armor to this armor the weight difference, but what matters is the level of protection, I get better protection. These plates seem high quality I wouldn’t go with any other brand.

  25. devon day (verified owner)

    They may or may not send you your entire order or only half of what you payed for from my experience. Buy at your own risk. But I’d reccomend going elsewhere

  35. Daniel (verified owner)

    Very competitive pricing, lead time. For side plates was 4 to 5 weeks. They shipped within one week which was very impressive. You can tell RMA offer plates that are top notch in quality and capabilities and at a price that allows almost anyone to afford such an essential piece of equipment.

  36. Jack (verified owner)

    Delivered Early!

  37. Daley Saxton (verified owner)

    Have yet to be shot wearing these. But they seem really nice. Price is fair enough. Fills out the side panels on my LBT 6094 nicely. I’d recommend them to the homies. Depending on how 2021 goes, I may or may not get back to yall on the ballistic performance. Stay swole kings!

  38. Michael C. (verified owner)

    Very impressed with the quality of the side plates.

    The Plates comboed with the Banshee Elite 2.0 provided a snug fit for a 5’6″ 200lbs person. This plate carrier does require separate side plate pouches to equip the side plates. Very pleased with this product.

  43. Anonymous (verified owner)

    The only level IV sideplates on the market

    Fit I the side pouch is great.

  45. Andrew (verified owner)

    Came wrapped very well to ensure no damage to plates occurred during shipping which made me very happy

  46. Anonymous (verified owner)

    A great addition to the main plates to protect the heart and lungs from side shots.

  47. Abraham M. (verified owner)

    Very nice 6x6s. They’re appropriately thick, so I had to modify the Crye carrier a bit. Just slightly heavier than other composites, but obviously lighter than 500 steel.

  48. Anonymous (verified owner)

    Nice looking plates, Great quality, received the plates soon than expected. I definitely would recommend these.

  49. Mason S. (verified owner)

    Good side plates that do what they advertise. On the heavier side, but it’s not a complaint at the price point.

  50. Kenneth (verified owner)

    Awesome and Top Notch. I’d buy again!

  51. Major A. (verified owner)

    Fits well in my Condor plate carrier. Glad for the coverage from such a well made product

  52. Derek (verified owner)

    I like these plates. They serve their purpose which is to prevent getting hit in the side. My only wish is that RMA would utilize the lighter weight on the G2 armor plate with these littler guys.

  53. Michael W. (verified owner)

    Side plates shipped much more quickly than the full size front / back plates. Quality appears fantastic as always! Would recommend and I will be ordering again.

  54. Bryan Ruud (verified owner)

    Good service and quality appearing product

  55. Johnny S. (verified owner)

    Great lightweight set and covered in some nice moisture wicking fabric. Curved nicely and comfortable. Nothing more to say. If you need side plates, you can’t go wrong with these.

    Wish I could have got these on the 99 dollars for a set deal but with all of the other discounts and near free shipping I can’t complain plates feel great and do not add much weight. Will buy one or 2 extra sets to store

    These plates are my second purchase from RMA and built with the same quality and attention to detail as the full size plates. They fit perfect and

    These small plates come in handy for vests that have side pocket for panels. A lot of armor vest that I have experienced only had soft panels so these level 4 side plates come in handy.

  66. Andrew P. T. (verified owner)

    Great 👍🏼 price 💵 for a great product!

  67. Nicholas (verified owner)

    Items are as described with fast shipping. Many fly by night companies do not do the heat, drop and water submersion testing per NIJ01.01.06 but claim “compliance” nearly all RMA products exceed these additional tests as well with certification. There’s no better product at that price. High grade armor at appropriate prices.

  68. THOMAS CROSBY (verified owner)

    Phenomenal company, outstanding customer service and prompt shipping. I genuinely enjoy doing business with this company!

  69. Armando (verified owner)

    Simply awesome not only that but I got that coffee from black rifle company and I am a happy man

  70. Aaron Elliott (verified owner)

    Awesome stuff! I’ve done some research on other companies. This is the place you want to get your armor.

  71. Antonio Gonzales (verified owner)

    Did not know that the plates were that small, i did not buy a vest with the need of side plates. But it looks to be a great product.
