The majority of my testing took place in a wooded area with soft ground cover and temperatures in the 50’s and 60’s. But of course, that rifle sports a ~17.5″ barrel, allowing for an additional seven inches of room for powder burn. To date, the quietest 5.56 rifle I’ve had the pleasure of shooting was a MK12 with an Allen Engineering (AEM5) silencer.

Is it the quietest I have ever heard? Hard to say. The Integra is very quiet for a 5.56mm round being suppressed out of a 10.5″ barrel. Luckily, this part is also relatively easy. With functioning, reliability, and accuracy out of the way, we can finally start talking about suppression. Overall, Gemtech has done a great job in producing a well made upper/silencer combination that feels as natural as any other complete upper from a top tier manufacturer. Also, the serialized silencer tube protrudes a little more than an inch from under the rail system. The titanium core adds very little weight to the end of the barrel, arguably the place where additional mass is least welcome. Which sounds obvious, until you remember that this is a compact package with no mounting systems and no need for an additional SBR tax stamp.

Bolt carrier and charging handle includedĮnough of the official data, what about the intangibles that can’t be quantified using weights and measures? Honestly, the Integra not only feels solid and well made, but it also is comparable to an unsuppressed short barreled upper in weight and a 16″ unsuppressed barreled upper in length.Material Titanium tube, gas block and core.128 dB (.300 Blackout with subsonic ammo).The result is an SBR with a total suppressed length of 18 to 20 inches. But adequately suppressing that shorty usually means adding a brake or flash hider mount, a mounting system, and of course, the silencer itself. After all, together, SBR and AR15 could mean a ~10-inch compact package. Looking at the pictures, ‘short barrel’ and the Integra may seem to be a misnomer. In what is being called the quietest 5.56 short barrel setup currently available, silencer industry stalwart Gemtech has designed the Integra – an integrally suppressed AR15 upper receiver group. Not to mention the supersonic crack generated when that ~75-grain projectile breaks the sound barrier. Containing a large amount of deflagrating powder as it leaves the muzzle results in extreme heat, pressure, and blowback – forcing even the best scientists and engineers to make trade-offs. Weight: Standard Configuration: 12.7oz Short Configuration: 8.Suppressing the legendary 5.56mm rifle round in short barrels is a challenge that silencer manufacturers have attempted to master for decades.Length: Standard Configuration: 7.8″, Short Configuration: 4.85″.Pistons, Fixed Mounts, Fixed Barrel Spacers and 3 Lug Mounts all are interchangeable with the Obsidian 9! We strategically place the engraving on the thickest cross section of the 17-4 stainless steel mount for fast and easy replacement should the suppressor become damaged beyond repair, it also serves to make the Obsidian9 infinitely upgradeable in the future.Īlready a proud owner of an Obsidian45? The Obsidian9 is fully compatible with Obsidian45 accessories. The Obsidian9 mount is machined from 17-4 Stainless Steel barstock. The Obsidian9/45 pistons are cross compatible with SilencerCo™ slotted pistons. This drastically lowers gas blowback for a more enjoyable shooting experience. The Obsidian9 and Obsidian45 use a non-slotted design creating a full circumference gas seal. With serviceability in mind the Obsidian baffles create a gas seal that virtually eliminates carbon build up between the baffles and tube. Obsidian9 baffles are machined from 17-4 Stainless Steel barstock, with three indexing tabs for proper alignment. With additional versatility in mind the Obsidian9 is fully compatible with suppressor sights for seamless use on a pistol or carbine. In a class of its own, the Obsidian9 is nearly half its size in it’s short configuration, giving you two suppressors with one tax stamp. 350 Legend (with a 16″ barrel or longer).Belt Fed Rated for Pistol Calibers up-to 9mm.With a diameter of 1.37″ the Obsidian9 is compatible with pistol suppressor sights, making it perfect for pistols or sub-guns.
