In June 1995, at the tail end of the Bosnian War, an American pilot, Captain Scott O’Grady, was shot down in his F-16 while flying a sortie over Serb controlled territory. For the next six days, O’Grady managed to successfully evade enemy forces who actively sought to flush him out of hiding. For the entirety of his six-day struggle, O’Grady miraculously avoided enemy contact and he never had to fire his issued 9mm Beretta M9. Yet if he had needed to use his weapon, its loud report would most certainly have doomed him.

 

At around the same time as O’Grady’s downing, Gemtech began development of an ultra-compact 9mm suppressor that could be attached to standard Beretta M9 service pistols and issued to airmen like Captain O’Grady. The timeline of these events, while compelling, is mostly a coincidence. Gemtech’s efforts were actually in response to the Army’s 160th Special Operations Aviation Regiment (SOAR). The Aurora is the product of that development effort and it has gone on to serve a healthy variety of special operations groups.

 

The Aurora is a unique suppressor. Rather than opt for a traditional baffle stack, the folks at Gemtech decided to equip the Aurora with a set of eight polyurethane wipes. Though these wipes are known to wear out rather quickly, Gemtech’s stated goal was that the parts last 15 rounds or so (enough to expend an M9 magazine) before needing replacement. In short, any engagements the Aurora might see were expected to be brief.

For most of the past decade, the Aurora has been something of a mythical beast within the civilian realm. Mostly, this is because the ATF has held that wipes constitute suppressor parts, making replacement infeasible for your average shooter. Gemtech also likely figured that the can was just a little too niche for civilian buyers.

 

There’s really no other way to say this: The Aurora is tiny. At right around 3.25” long and 1.125” in diameter, Gemtech’s miniature silencer is the smallest I’ve ever reviewed. In fact, it’s precisely the same size as the Innovative Arms Slingshot Micro.  But of course, the Micro is a rimfire can and that comparison is hardly fair.  From a weight perspective, the Aurora again trades blows with rimfire suppressors.  It weights 3.1 ounces with a fresh set of wipes.

 

 

The Aurora 2 comes with dual-threaded end caps.  One end of the can will be threaded 1/2-28 and the other will sport M13.5×1 LH threads.  The Aurora is made entirely of aluminum, save its threaded rear cap and polyurethane wipes.  In contrast to conventional suppressors, you won’t find a single baffle inside the Aurora.  Instead, Gemtech’s silencer uses a series of eight polyurethane (rubber) wipes and three aluminum spacers to create a quasi-baffle stack.  When assembled, the whole wipe-spacer unit is coated in petroleum jelly (Vaseline), which serves as an ablative medium and enhances suppression. The beauty of petroleum jelly is that is lasts for a very long time. You can leave the Aurora “packed” for months or even years and the jelly won’t dry out. It also happens to be very messy.
In a silencer this small, wipes are just about the only way to achieve acceptable performance. Durable baffle systems quiet a firearm’s report by controlling gas flow, but they have to allow a certain amount of clearance for the bullet to pass through – lest a catastrophic baffle strike would occur.  The inside of the Aurora is far less spacious than other cans, so Gemtech had to be far more aggressive in designing a silencer that stops gas in its tracks.

 

The rubber wipes accomplish Gemtech’s goal because they’re designed to physically touch the bullets as they pass through. This interaction creates a gas seal around the bullet and impedes forward-moving gasses. It also means that you can NOT use hollow-point rounds with the Aurora. Just don’t do it – they will expand prematurely and at best, you’ll end up with a damaged end cap. While the wipes do wear out in relatively short order, they’re quite effective up until that point. If you think about the original requirements, so long as the wipes make it through the 15-round magazine of the M9, they’ve done their job. Since the Aurora contains eight wipes, it actually takes a good bit more than 15 rounds to fully exhaust the core.
You don’t need a booster to use the Aurora on common pistols.  Noticeably absent from the Aurora is any sort of booster or Nielsen device. Whereas the weight of most pistol suppressors necessitates a booster to help “unlink” the can and barrel for reliable cycling, the three-ounce Aurora is light enough to forego such features. That’s a good thing too, because there isn’t any space for a booster inside such a tiny silencer.

 

 

Suppressed firearms have two options when it comes to gas management – release pressure through the front of the can or allow it back into the barrel and receiver. The former option results in relatively poor decibel readings at the muzzle, but it also results in a silencer that sounds better (and is actually quieter) to shooters. With the latter, the exact opposite is true. The Aurora is tasked with the almost impossible challenge of capturing gasses that would normally be allowed to expand into a much larger suppressor. So long as the can’s wipes are in good shape, they impede forward gas movement (and rearward to a degree). The gas must go somewhere, though. Most of the time, this means it heads back at the shooter through the firearm’s action and ejection port.
