7.62mm Advanced Armor Piercing Bullet Unveiled by Stiletto Systems

In an era of increasingly resilient body armor, new small arms ammunition solutions are required to even the odds between the shooter and shootee. The company Stiletto Systems, based out of the UK, is advertising its new bullet as a possible solution for this problem. The round, a relatively conventional 7.62mm tungsten cored armor piercing projectile superficially similar to Nammo’s M993 round, is advertised as having considerable penetrative power: 20.5 mm of rolled homogeneous armor at 100 meters, 100% of the time.

Their 5.56mm variant deserves some mention as well: It launches a very heavy 82 grain tungsten cored projectile at 2,720 ft/s muzzle velocity from a 23″ barrel. This reportedly gives it the power to punch a 10mm RHA plate at 450m, which implies a substantial effective range versus hard ceramic armor.

Stiletto demoed their weapons in a video published via Defence Blog just a few days ago. It is embedded below:

The Stiletto Systems product presentation, available here, is full of interesting – although sometimes quirky – concepts, including caseless 40mm grenades launched from a sniper rifle esque platform (reminiscent of the 25mm Barrett XM109), and an “advanced” pistol that looks like a hybrid between a Beretta 92 and a Wildey, but that shoots both 9x19mm Parabellum and 7.62x25mm Tokarev.

  • Chatterbot

    I believe company owner is actually based in/from Ukraine

    • That would also explain why they are basing their penetration on Russian armor standards such as “2P armor.”

  • TheNotoriousIUD

    Nice tactical beach towel.
    Dude looks like he just invaded Ukraine.

    • hikerguy

      When I first looked at the video before I read you comment, I thought it was a wild bathroom rug for a sec.

    • randomswede

      They could easily just have not filmed his face, even if they did it’s unlikely anyone would be able to ID him as being a ex-super-secret-squirrel.
      That all makes me assume this is a dude playing dress up for the camera; a company polo shirt and an “F-U” baseball cap would have looked more professional.

      This is a new Ukrainian unmanned rocket launcher. It is called Phantom. The head of the Defense Council of Ukraine said: “Now, seeing this machine our enemies will surrender without fighting”.


  • RSG

    Is like a case, just in case.

    • Interesting… I wonder if they have a UK office, or whether this is supposed to mean “Ukraine”?

       Stiletto is a UK registered business with all manufacturing and exports
      taking place from the UK

      • int19h

        Their LinkedIn page says that they’re headquartered in Suffolk. Probably just the head office, patent registration etc though.

      • Абалкин Леон

        In Ukraine today much talking abaut build new ammo plant, and Stilleto wants be the main pretendent for this bisness.
        The beneficiars Stiletto, i shure, 100% Ukranian Businessman or some burokrats group hu wonts have that “piece of pie”

  • iksnilol

    What’s quirky about a 40mm grenade sniper?

    Or a pistol that can shoot both 9×19 and 7.62 Tokarev?


    • PK

      I think it has more to do with being an odd idea for viewership in the West, mainly.

    • ostiariusalpha

      There’s at least 2 choices for the pistol mag: go with a 9mm width mag and have the 7.62 Tok loaded in a semi-stagger pattern (like the Savage 1907 and HK45); or have the mag width for a true double stack 7.62x25mm and use internal ribs on the 9mm mag. Seems like they went with the first option.

      • iksnilol

        Then why did they manage to fit 15 rounds in both calibers.?

      • 7.62x25mm and 9x19mm have the same base diameter. The magazine well just has to be long enough for the 7.62x25mm.

  • No mention of their coolest round: the “Ramjet powered” tungsten tip 9mm.

    • PutinBot

      Didn’t that guy who tests weird shotgun slugs at full30 test “ramjet powered” slugs and concluded it doesn’t work?

      • noob

        even if the ones tested didn’t work, rocketry is one of those things where a small change can be the difference between working and not even remotely working.

  • PutinBot

    7.62 tungsten core AP round?
    40mm caseless grenade launcher?
    Sure, let’s take all decades old Soviet tech and try to sell it as innovative.

    • noob

      Decades old SPACE AGE Soviet tech.

      I am so sad that the space age has been over for like 50 years.

  • The pistol looks more like the Croatian PHP, but retaining a bit more DNA from its Walther P38 ancestor.

  • micmac80

    Its an Ukrainian project and company that is trying to play UK brand.

    • mosinman

      oh that’s nice!

  • Waskoley Wallaby
  • Ευστάθιος Παλαιολόγος

    I,m a bit confused. Is this round 7,62×51 or .300WM?

    • Giolli Joker

      In the video they say .300 WSM (Winchester Short Magnum).

  • Waskoley Wallaby
  • Jimmy the cracker of corn

    Is it me or does writing ”technological secret sauce” in a product presentation material just make it lose all seriousness?
    hehe…..technological secret sauce….

  • ActionPhysicalMan

    The website reads like bad science fiction.

  • ActionPhysicalMan

    I have never seen tungsten carbide cored bullets for sale on GunBroker and M80A1’s steel penetrators are no where near as dense or hard as tungsten carbide. Last summer a bunch M80A1 bullets were sold by American Reloading for $1.70 each and now this guy wants to sell them for a at least $5.20 (probably much more) each having added maybe 60 cents worth of brass, powder and primer. I suppose that if they aren’t going to turn up at AR again, that may be the market price. I wish I ‘d bought more than I did when they were readily available:-(

  • toms

    These AP have seen limited use by Ukraine SF.

    • Any more info on their use / performance?

  • Kelly Jackson

    Can it defeat a piece of rebar though?

  • Martin T

    Dang I want that 82 grain pill just as components… any word on that?

  • Warren Ellis

    Having nkt read the links, does anyone know what makes this bullet so great from what images you can see of it? Does it use some new property of this company’s bullets or uses new super materials or what?

    Because this: The round, a relatively conventional 7.62mm tungsten cored armor piercing projectile superficially similar to Nammo’s M993 round, is advertised as having considerable penetrative power: 20.5 mm of rolled homogeneous armor at 100 meters, 100% of the time.

    Sounds like BS.

  • JamesDrouin

    Unimpressed, armor is almost always sloped, which has a major effect on penetration.

    Oh yeah, and it’s a third-rate video production to boot.
