Stealth Engineering Group’s Folding Suppressor (And Other Cool Stuff)

DSC006752

Stealth Engineering Group occupies a small booth on the first floor of the Sands expo center, but their display case is packed with products and engineering ideas. SEG makes suppressors, and advertise a lighter, more accurate, lower cost, and more customizable product than their competitors. CEO Rob Morrison also designs their products, and is a major “suppressor guy”, able to talk at length about the subject in general. Speaking to him definitely made me wish I knew more about the subject.

…And now you don’t see me.

SEG’s most eyecatching product, a very tightly machined folding suppressor mount with modular threads at both ends, was designed to solve a specific problem: According to Rob, the need for quick-detach suppressors led to them being produced with machine tapers – the same high precision male and female tapers used to attach tools to a mill’s spindle, hence the name. This taper works well when a tool is being mounted and dismounted regularly, but users were apparently having problems with quick-detach suppressors sticking to their mounts after hard and constant use, resulting in a can that couldn’t be dismounted from a rifle. Rob’s solution to this was to create a high precision folding suppressor mount, which not only allows for convenient stowage (alongside the gun) of the suppressor when not in use, but also acts as an adapter for mismatched threads on the suppressor and barrel. Threaded segments allow these folding mounts to be modified to accept any sort of thread; and SEG advertises that they mean any sort of thread. If they do not have the tooling to make it, they say they will get it, at not cost in dollars or time to the customer.

Having a little machine time myself, I was highly impressed with the amount of work put into SEG’s folding suppressor mount. In this version, the latch is integral, but Rob says he is working on a replaceable latch, as it is a wear item.

If you so desire, you can also get your suppressor in a tempered finish from SEG that is both attractive and, Rob says, twice as durable as a standard finish. This finish is patent pending from SEG, and I am told it involves considerably more than just tempering the can until it’s more colorful. The finish comes in both polished and unpolished styles.

Finally, SEG also had on display a patented stamped steel suppressor baffle design. This design reduces cost though an inexpensive stamped and folded baffle assembly. SEG advertises suppressors as inexpensive as $200, the cost of a tax stamp.

    hw-whoow, now that is a very good invention, and i love the urban camo too.

  • Giolli Joker

    Impressive!
    Very interesting design and execution.
    And they’re website is NOT full of marketing/operator/tactical BS like too many we’re encountering in these days.
    Thumbs up for SEG.

    • I was really impressed, I have to say.

      • Giolli Joker

        Actually I like shows like SHOT for hidden gems like these. much more than for the new releases of the big names.
        Thanks for letting us know about them, keep on looking for intriguing small booths. 😉

  • bbmg

    Brilliant – now that’s the sort of R&D that should be happening as opposed to regurgitating ARs and M1911s.

  • gunslinger

    gimme that camo!

  • JumpIf NotZero

    Sweet!!! Now you can put a folding suppressor on your TP9… Probably the worst suppressed gun I have ever own / shot.

  • sianmink

    That’s.. awfully neat. And I like their finish and pricing too.

    • JSmath

      That finish is definitely appealing, I think the appeal would wear if everyone started doing it, though.

    Well, I’ll be damned.This is pretty wild.
    I’m tipping my hat, Mr. Morrison.

    And he even makes it out of titanium! (Optional.)
    The first thing I thought when I saw this was “titanium, the weight, the weight!”,
    and lone behold, it IS available in titanium.

    Weight is everything.

    Excellent, excellent work there. Expensive part, but it looks like it’s worth it.

    I hope we’ll see a lot more coming from this gentleman!

    There are two things I don’t understand:
    I. What provies retention for the suppressor in the closed position?

    II. I can see the cylindrical male-female thing in the center, and it looks like a precisely machine part too, but without an O-ring, how does is seal pressure?

    Metal on metal seems a bit odd, doesn’t this hinder the performance of the suppressor?

    • There is a latch that holds the mount shut. It was a very solid system.

      • Adam aka eddie d.

        Sorry Nathaniel, I think I haven’t used the correct expression there –
        I meant folded down, not closed [ready to shoot].

        I saw the latch button, I just guessed when folded down it didn’t provide lockup, since different handguards allow for different clearence,
        not every one of them allowing to be fully folded down.
        A Moe handguard for instance is a lot wider than a Noveske or a Strike I., BCM handguard.

        If the latch can’t lock the mount in the folded position,
        the suppressor may become a dangling dead load, that’s what I was trying to say.

    Now my new suppressor can match my Strider knives…

    I’m surprised the Department of Defense hasn’t approached him for a few samples.

    Stealth Engineering Group 推出可以折疊滅聲器的配件(不用滅聲器時,可以像摺疊拖一樣收起來),還有可以沖壓製造的滅聲器

    f**k prc

  • Joe

    If it locks in the open position, I’m sold. SHOT seems somewhat mundane this year, I’m glad to see some innovation.
