With some new, additional NFA barriers eliminated, I find myself rethinking niche suppressor designs that used to feel too costly to justify adding to the collection. Wipe-equipped cans use thin, often rubber, discs that the bullet punches through for superior gas sealing. On paper and often in video games and in movies, they promise exceptional, virtually Hollywood-quiet suppression in ultra-compact packages.
However, in reality, they come at the expense of a short lifespan and or a more frequent and often tricky maintenance routine to be at peak effectiveness. I see models like the Gemtech Aurora 2 available through Silencer Shop as more tempting complementary tools now, even if this one example does require replacement of not just the neoprene wipes, but also the gel between the wipes. Today, I’m going to break down whether the unique benefits that wiped suppressors offer outweigh the hassles.
I personally believe the recent shift in tax policy regarding NFA items opens up exciting possibilities for collectors and shooters who value specialization or novelty as their NFA collection begins to grow.
What Are Suppressor Wipes?
Suppressor wipes, for the uninformed, are thin, flexible discs, typically made from rubber or neoprene, stacked inside a suppressor right along the bullet path. Each time you fire, the projectile punches through the wipe, aided by some small perforations in the disc itself for even breakage. That wipe then momentarily seals back around the bullet’s path to trap and slow the hot propellant gases behind it. This setup delivers sound reduction that often beats what rigid metal baffles, or even modern intricate 3D printed designs alone can manage, especially inside ultra-compact suppressor tubes like the Faxon Twenty-Toucan.
What I love about wipes is how they give you a true Hollywood-quiet, even eliminating first-round pop – another side-effect benefit of the design. The wipes do this effectively by containing those initial oxygen-burning gases inside the can and combusting them there rather than outside the can.
Sure, this means that the wipes are going to erode pretty quickly after just 15 to 25 rounds per set, making them far more sacrificial than your typical durable stainless-steel baffle stack. But that short lifespan is the price you pay for their unique physics-defying performance, and it’s also why these types of suppressors have probably the smallest niche use-case of any off-the-shelf suppressor out there. They can’t handle the pressures and heat that come with most firearms.
Historically, early wipe concepts came from military demands for discreet pistol and SMG setups where gaining the most sound suppression was the goal. While older traditional baffles have been around since the original suppressor, a number of pre-1970s suppressors incorporated wipes, too, which delivered solid performance but once again relied on materials prone to rapid deterioration under intense heat exposure.
During much of the 1970s, various manufacturers finally started getting into refining the performance of suppressors, and by the 1980s, new designs like the K-Baffle came out, changing the landscape forever. These K-Baffles outlasted wipes while giving suppressors a much better suppression profile, especially in tandem with subsonic ammunition.
Current Availability
Today, however, you won’t find many modern suppressors leaning on wipes anymore, partially because of their military use-case origin, but mostly because of that consumable nature I mentioned earlier. I have a handful of friends who own some pretty unique suppressors, including ones that use wipes, but these guys are typically FFL/SOT holders due to some legal issues we’ll talk about later in this article when it comes to maintenance.
For now, Silencer Shop keeps the Gemtech Aurora 2 in stock, and it’s a rare example of a wiped suppressor that often doesn’t get a lot of attention. This little 9mm pistol suppressor clocks in at just 3.3 inches long and a featherweight 3.2 ounces. It layers multiple neoprene wipes with aluminum spacers – and yes, that signature gel in between – to squeeze out maximum quiet from the tiniest possible package. Perfect for compact hosts, but honestly, I’d save it for low-volume sessions rather than blasting through mag after mag.
The Aurora 2’s design is obviously intended to be a nod to the specialized military heritage that suppressors have. On the Silencer Shop product page for it, they even describe it as a novelty piece for us mad men chasing the holy grail of suppression.
What really grabs me about this one is how it evolved from the original Aurora concept, polished up for civilian hands while holding onto that impossibly short profile. Thread it onto a subcompact 9mm like a Glock 43X or a Hush Puppy Kit, and you’ve got a rig that’s much less bulky than options with boosters. I can picture it excelling in discreet range practice or, for most of us, an interesting range toy.
The B&T Station Six is another wiped option that I’ve had the pleasure of shooting quite a bit over the years, and is higher in the list of guns/suppressors I’d buy if I had the cash for it. What makes the Station Six pistol double quiet is its unique bolt-action design that also eliminates the chance that the bolt tries to cycle and by extension, generates extra noise.
This is a rather expensive option, and without the wipes or a sound mitigating fluid inside of the can, its rather loud and is particualarily hard to shoot accuratley with its extremely heavy trigger. Either way, its one that everyone always wants to try and shoot, even if it does seem pretty impractical for a modern Welrod.
Legality of Replacing Wipes: Your Wipes
People often think that suppressors need to be sent back to the factory every time for service, and that’s not necessarily true. However, first and foremost, you probably should follow whatever the manufacturer says to do in terms of maintenance. While it is indeed true that the ATF blocks direct wipe sales to customers, swapping them out stays pretty straightforward and can even be done by your local FFL, or a customer with enough gumption (and some thorough research).
Manufacturers, like B&T, Gemtech, or Dead, are allowed to ship fresh wipes to FFL dealers, who can then handle the gunsmithing work and installs for worn wipes. If you’re a DIY or weekend warrior, with a bit of thinking and clever hardware store crafting, you can easily make your own substitutes. Just remember that the ATF is pretty specific on the number of wipes/parts that go into a suppressor, so no extras are allowed; match old for new in a direct trade every time.
Federal regulations don’t allow the end user to keep spare silencer components just sitting around or have them ordered as spares from manufacturers outright, so that means if you do make your own wipes, you can’t make extras; you can only fabricate precisely what’s needed to swap out the shot-out ones directly. Yeah, it’s absurd that you can’t just have some extra pieces ofcut rubber circles sitting around, but this is still one part of the suppressor game we have to play for the extra bit of performance.
The Dead Air R-Series Wipe Cap Assembly ($149) gives R-Series suppressor owners (Sandman series, etc.) an easy bolt-on wipe upgrade for extra dB reduction. It ships with almost everything you need for the extra DB reduction, but as we talked about earlier, SiShop can’t just send you a wipe, so this kit comes with no wipe, and you’re kind of expected to provide/source your own.
You can make replacement wipes from neoprene, polyurethane (urethane), silicone, or other pliable rubber-like materials. The layered discs will do a good job of sealing gases and muzzle blast between each level for superior sound trapping. However, you shouldn’t just use anything (although you could). Instead, there are a few materials and, more importantly, hardness guidelines for selecting DIY replacement parts.
Wipe material gets measured on the Shore hardness scale. These are dimensionless units from 0-100, denoted as Shore A (softer rubbers) or Shore D (harder plastics). For suppressor wipes, we live in Shore A territory (30A-50A) where the rubber flexes just right around passing bullets without failing instantly.
30A would feel like a wetsuit liner or soft gel insoles and gives maximum seal for whisper-quiet subsonic 9mm, but it burns out after a lower number of rounds.
50A polyurethane gaskets take more heat and punishment for a higher round count durability, but may tear and cause bullets to yaw. Some factory wipes are typically rated at 40A, but they often use specially formulated materials that resist heat and wear better than DIY replacements.
DIYers can grab these from online stores like McMaster-Carr, marine chandlers, or hardware stores like Home Depot or ACE. While you can order the proprietary polymer parts that outlast hardware store parts, you’re replacing a lot of time waiting and expense with a chaper more consumable alternative you can do at home. Your results will vary by host gun, ammo, and how precisely you match factory bore alignment, and of course, how durable your replacement material is.
Are They Worth It Now?
Wiped suppressors really only do one thing well. They’re perfect in those targeted scenarios where plain old baffles just can’t keep up, and you want the maximum amount of suppression you can get without the added mess of suppressor gels or using a wet can.
That said, for my everyday range trips, I still run my normal suppressors. While not as quiet or cool, they’ll easily and thoughtlessly last thousands of rounds without the need for me to take them apart and service them every handful of magazines, letting me concentrate on trigger time instead of playing suppressor mechanic.
Yes, hands down, if you are into having some of the quietest range sessions you can imagine. Something like a B&T Station Six or Gemtech Aurora 2 from Silencer Shop to round out your traditional suppressor collection. Again, the $0 tax stamp means a lot of people now already likely have a handful of suppressors, and this is just unique. Right now, wipes are probably going to be most attractive for those of us who already have a suppressor for every gun and are looking for something new to scratch the NFA itch.
