Universal Suppressor System from Griffin Armament: The “Optimus”

One of the biggest detractions I have had over suppressors has been their lack of modularity. Often, they are set for a specific thread pitch and/or caliber and one was forced to buy a new can for nearly every rifle if you always wanted to shoot suppressed. To correct that, in steps Griffin Armament with their new Optimus suppressor system.

Innovation comes in many sizes (like Griffin’s martime receiver extension). In short, its a fully modular suppressor system capable of tackling the diminutive 22LR all the way through .300 WIN Mag. By serializing only the sleeve, Griffin Armament has set up the can to expand and contract with fully removable (and easily cleanable) components.


The can is also compatible with 9mm weapons systems and has the option of adding a booster to ensure reliable function with semi-auto handguns.

Mounted to MP5 with optional tri-lug adapter.

The can is running at a scant $1,095 and includes components to be able to adapt to 9mm, 22LR (and by extension, .223/5.56), and a Griffin 5/8×24 minimalist brake mount. The can is compatible with 3-lug mounts, but it is not included.

Details from Griffin Armament, as there is just way too much to cover:

The Optimus Silencer is the most significant advancement in consumer silencer technology in the last decade. A truly high performance and versatile silencer, the Optimus can service many firearms from rimfire calibers up to 300 winchester magnum. Utilizing full 17-4 stainless construction with user adaptable components the Optimus in its full size standard configuration is a 9.4” 18.5 ounce, taper mounted 300 Winchester Magnum rated silencer. A 7.9 inch 16 ounce 308 rated Mid Size Taper Mount configuration can be attained using the optional minimalist brake shield. Re configuring the suppressor with the included booster assembly and piston, the Optimus transforms into a high performance, reliable, 9mm pistol silencer. The optional low profile 3 lug assembly can also be interfaced with the Optimus pistol configuration, providing secure attachment for 9mm, 556 and 300 blk out carbines. Additionally, the user can enjoy quiet rimfire shooting by switching end caps to the included 22 caliber end cap. After use the Optimus can be fully disassembled for cleaning by removing the patent pending Taper Lock interfaces.

The Optimus silencer transforms into multiple configurations to suit the shooters requirements on various platforms from rimfire to 300 win mag. Full spectrum versatility, in a single, durable, user serviceable silencer is now possible with the Griffin Optimus.

Includes: 9mm and 22 caliber end caps; full booster assembly,1/2×28 piston, and 5/8×24 30 caliber Minimalist Brake Mount.

9mm can only be fired in short length.

  • Jeff Smith

    I watched Miltary Arms Channel’s video on this last night. I need this immediately.

  • Sianmink

    Looks like a nice system, I especially like how the recoil booster is also a disassembly tool.
    Looks like the only drawback is that it’s kind of heavy.

    • Laserbait

      I have the SilencerCo Omega, and it’s a great can. It’s about 3oz less than this one, in its full size config. I was amazed at how much I didn’t notice the weight hanging off the end of the barrel.

      If the Griffin were available at the time that I bought my Omega, I’d have a really hard time deciding.

  • JumpIf NotZero

    I’m seeing direct knockoff components from at least three different companies. Those are clearly SWR barrels, AAC’s main tube, dead air or sandman extension (I forget which one), the end cap looks framiliar and I’m sure that booster is internally similar to AACs or maybe Gemtechs.

    To watch their own, but this is definitely not for me.

  • thedonn007

    It is too bad that, due to the ATF, you cannot change the baffle sizes as well.

  • Justin Galt

    Good job fellas, send us over one!

  • mosinman

    this would be the suppressor i would buy if it wasn’t for our current laws on them

    • iksnilol

      This suppressor was kinda made for the American laws.

      • mosinman

        yes, but even if we received more reasonable suppressor laws this would still hold appeal, because you’d buy one system and use it on multiple platforms

        • iksnilol

          It is pretty reasonably priced, but if you had reasonable suppressor laws other suppressors would fall in price and they would work better.

          The disadvantage I see with it is that it is pretty long, and you can’t change baffle sizes.

  • USMC03Vet

    I hope it comes with good directions. I’m already confused.

  • that price tag is a bit rich.

  • Dave D

    This should be a good seller for Griffin given the current NFA for the same reasons people buy a 45 cal pistol can and shoot 9mm or a 30 cal can to shoot 5.56. Having options is a good thing when your having to deal with NFA regulations/tax. I’m still waiting on independent numbers before I make any opinion on the Optimus. My concern is that you have to make sacrifices to handle multiple configurations and this will by a jack of all trades and a master of none. Although I would love to be able to shoot a couple of 5.56 rounds out of my 22lr can to help clean the lead out.

  • Mark

    Am I mistaken?—I thought that suppressor parts were a federal problem.

  • allannon

    The link to the maritime extension is broken, seems to be pointed at the page to edit it.

    Regarding the can, sounds neat. Any chance of a hand’s on?

  • Mazryonh

    I know at least one writer on this blog is/was a fan of the S.T.A.L.K.E.R. video game series. That writer might remember the English description for the suppressors in that series. It went something like “this silencer includes a set of adaptors to allow it to fit any caliber.”

    Fiction, meet reality.

    (Still, I don’t think that this new suppressor’s compatibility with 9mm rounds includes the Russian 9x39mm caliber, unlike the version found in the S.T.A.L.K.E.R. game series.)

    • iksnilol

      9×39 is actually 9.3×39, so you might have a point there.

      • Mazryonh

        And then we have 9x18mm Makarov, which has a bullet diameter of 9.2mm (so as to be useless for NATO guns if captured).

        • iksnilol

          Oh no, that’s for increased stopping power. Trust me on this one 😉

  • myndbender

    I’d like to see how this compares to the Liberty Mystic X can. It seems the Mystic X is a bit cheaper, but doesn’t come with as many mounts included as the Optimus. Will wait for someone to do side by side testing to reach my verdict, but it does seem like a typically well thought out Griffin product w/ all the extras.

    • Cymond

      And also the SilencerCo Hybrid. It seems that most of the hype from their recent product announcements was focused on the Maxim-9 and the Micro Osprey, but they Hybrid will handle up to 458 SOCOM and 45-70.

    • Matthew Martins Gonçalves

      The problem is, with the Mystic X, is that it only goes up to a .308 win. subsonic at that… And then the can can only handle 5.56 with a minimum of a 16″ barrel.. As opposed to the Optimus that can handle all the way down to a 7″ 5.56.
      If the Mystic X had a little bit tighter tolerances and was threaded at the front of the can to handle a little more pressure it’d be able to compete with the optimus.
