Lightweight Armor from RMA Armament

Those of you have that have worn plates, did you wear steel or ceramics? I was issued ceramic plates (ESAPIs), and while lighter than steel (the ESAPIs were somewhere around 6 lbs each, if I recall correctly), were pretty bulky.

RMA Armament has a solution that is roughly a third of the weight, their new “SRT” Hard Armor Plate. And even cooler is that they are about a half inch thick.

RMA’s “SRT” hard armor plate is designed to provide multi-hit protection against some of the most common high speed rifle rounds in the world today – the 7.62×39 (M67 Lead Core), 6.8×43 FMJ and .556×45 ball rounds.

Most impressive is that this SRT plate – comprised of UHMWPE material – can stand up to a ballistic beating of the aforementioned nature while weighing just 2.05lbs, which is just a fraction of the weight typically needed to defeat such high velocity rounds.


  • Special Threat, Multi-Hit Tested by an NIJ Certified Laboratory
  • Special Rifle Threat Stand-Alone
  • Constructed with Ultra High Molecular Weight Polyethylene
  • Single Curve
  • Shooter’s Cut
  • Positive Buoyant
  • Waterproof
  • Made in the USA


  • 10″ x 12″
  • 2.05 lbs (.93kg)
  • Thickness: 0.56″

I suppose it is cool that they are buoyant, but I’m not sure that will make much of a difference with all of the other crap that is generally attached to a plate carrier. The savings of weight that is equivalent to a gallon of water, along with the lower profile would definitely have been nice.

Okay, so now let’s queue up some stories of the armor you all have carried…

    These plates don't compare to ESAPI with their level III rating, they compare better to SAPI (which are only 3-4lb each). SAPI are thinner than ESAPI as well. This isn't very amazing.

    Anybody like Armour Wear? They have a III+ plate that's rated for 855 that is 4.5 lbs...
