Suppressor Sock Makes Quiet Cool

A young company called War Sport Inc., of Robbins NC, is revealing an interesting bit of “clandestine” kit this week at FPED VIII, if clandestine is the right word for it—the suppressor sock. Designed for the best “barrel thermal management”, the suppressor sock is full-auto rated and has been tested on 5.56, .308, .338, .416, .50 and all sub-calibers.

Joey Boswell, the engineer behind suppressor sock and co-owner of War Sport Inc. says the main purpose of this design is to further reduce signatures of our operators, by reducing the thermal signature of their weapons and degrading the mirage effects of a hot barrel. This is certainly a valuable attribute for our boys working against bad guys with thermal optics, and not necessarily just those we’re fighting right now.

“We’ll also be making models with removable high-temp rubber disks that act as a dust cover and can be fired through,” he advised, “which will further lower the dB on a cold bore shot, though this is just 5.56 and sub-calibers only.”

He cites further benefits of the suppressor sock, including the prevention of ‘branding’ your buddy in a stack or the cramped confines of a CQB environment and mitigation of mechanical noise during rifle placement. The primary advantage remains, of course, the sock’s ability to mask high temperatures, as seen below. The pictures below show a hot can (306 deg F) on its own after firing 5.56mm, then fitted with a suppressor sock.

The suppressor sock is odorless and smokeless, is a single piece design without zippers, Velcro, clips or other fasteners. Its FR outer skin is Berry Compliant and frankly just looks cool. They’re currently available in Multicam, OD, Coyote, Black and Army ACU Digital. They also provide optional full-barrel coverage.

The suppressor sock is rated and tested 1,700+ deg/f conductive heat and 2,100 deg/f Radiant, with thermal testing performed by certified 3rd party thermal scientists and several T&Es have been accomplished, with more in progress. MSRP for the average model without a barrel sleeve will be $149.99 each. Contact War Sport Inc. for more information.

    A quick trip to WSI website revealed no details, not even a mention about this product.
    I was specifically wondering about any detrimental effect on the covered suppressor or barrel weapon.
    If it merely hides the thermal signature then it would be logical to assume that the heat is being confined
    to the metal. Too much heat containment would be a bad thing for the suppressor & firearm. But if it dissipates
    the heat, that’d be great. Which is it?

    great, we can hide the end of the barrel but what about everthing else? kind of a waste no?

    @ Michael; are you serious? They offer something for the rest of the barrel, and you can cammie or paint the remainder of the weapon. That’s like saying, “Great, we have a ghillie suit, but what about my face? Kind of a waste, no?” Unless we’re misunderstanding your question, in which case please elaborate and we’ll try to answer. Of course, the biggest problem with Big Army, Big AF, etc, is that you’d be better off taking a dump in the middle of the chow hall in front of everyone than painting your weapon. You’d get in a lot less trouble anyway.

      ok, let me tell you that you can see the person regardless of hiding the barrel….that is point…

    Great article Mad Duo! This looks like an awesome product! I can’t tell you how many burn injuries I’ve treated after someone caught a hot suppresor or a hot barrel to the crotch. Not the kind of injury you want to get by the way. During transitions this happens more than you think, and its a big reason I’m a huge advocate of longer handguards. This would also be nice for a combat medic. I’ve been in combat operations firing my weapon only to find myself having to treat a wounded teammate. To do so I usually sling my rifle across my back. This is a situation where I can get burnt or burn my patient with the end of my barrel. I think this product would help tremendously in those instances.

    I can also say that we have found insurgents using thermal and night vision equipment more and more these days, and it is getting harder to hide from them during operations. I can’t wait to get one of these on my carbine and put it through its paces. We have been using other kinds of suppresor covers for a while now but this looks like it could be a better option if it does what it says. Having a sock on your suppresor AND your barrel is ingenious.

    was wondering anyone have any guidance on use of supressors by our military. besides use by jsoc wondering if there is any guidines for aquaring for us grunts on usage of them on. ie. if i orderone for work weather it will be allowed or if it has to be issued and so forth

    This is simply a repurposing of DEI and other spark plug boot insulators to reduce heat affecting silicon plug wires on racing engines.

    ACU Gray, at your local auto parts store. Most boots are woven to fit a 1″ diameter. and the maker also offers stainless tie wraps to secure it.

    If you run a hot barrel in ops or on a range, and can secure this over the exposed barre/FH/suppressor, why not? It prevents burn injuries to the shooter or other team member. It’s one reason I built a dissipator AR – rifle length handguards do that for almost no extra charge.

    Tie wraps would become heat conductors making it very visible under IR/Thermal viewers. The Suppressor Sock does not make use of any mechanical devices to adhere the material to a barrel or suppressor. The Suppressor Sock manages “Conductive” heat and manages “Radiation” from heat protecting the operator from the “bad guys” Thermal detection devices.

    This is something that will probably be standard issue in 30 years when our enemies actually have thermal optics.

  • ian

    Or… you can just use wrap it in cheap fiberglass fabric and spray paint it……

    If you’re worried about branding your buddy then wouldn’t a whole barrel sock be better?
