Silencer assessment: CGS Hyperion and Hyperion k

The CGS community Hyperion has lead the business in .30 cal sound suppression prowess for years thanks to its wonderful, patented inner structure. Now, with the creation of metal 3D printing (called DMLS, or direct steel laser sintering), CGS has been untethered to create inside geometries which are impossible to machine. Upgraded and quieter than ever, the brand new CGS Hyperion and Hyperion okay have just hit the market, and we went hands-on . . .

each and every of the new .30 caliber Hyperions is made completely of DMLS titanium. The “3D printing” system involves depositing a first-class layer of Ti dust then using a magnificent laser to sinter, or melt/fuse/weld, this new layer to the outdated layer in precisely the precisely desired locations. Then an additional layer of filth, a different circulate of the laser, and repeat unless your end product is built one teeny micro-fraction-of-an-inch layer at a time. Unsintered Ti dirt can be blown out as needed during the construct technique in order to avoid it from becoming trapped inner interior constructions.

trust it or not, what you emerge as with is a really monolithic end product that truly has a greater consistent, finer steel grain structure with fewer (like, zero) metallurgic imperfections than you find internal a solid or solid product, or a product that’s machined from a billet / forging or casting.

Left uncooked, the layer-by-layer technique is seen if you appear carefully satisfactory; ecertainly on angled surfaces (see beneath). If machined, you’d under no circumstances recognize.

both of the new Hyperions employ a 25-degree taper area earlier than the mounting threads. in case you’re installation a Hyperion for your SIG SAUER (creators of the 25-degree tapered shoulder) or a firearm that borrowed the SIG taper design, go forward and thread the suppressor without delay onto the barrel. That taper will supply a gorgeous, full fuel seal together with hugely increased mating floor area, which does wonders to aid prevent the suppressor from coming free all over use.

On most barrels with a typical, rectangular shoulder, you are going to likely want to run CGS’ new Hyperion Thread Adapter. obtainable in both 5/eight×24 and 1/2×38, the thread adapters comfortably convert your rectangular-shouldered muzzle into a taper-shouldered muzzle, throwing the mandatory 5/eight×24 threads out in front of the taper.

[EDIT: CGS informed us that the mount portion of the production Hyperion (these two cans were pre-production, but there are no other changes other than to the mount area) is fine for use on square barrel shoulders as long as the shoulder is over 0.735 inches in diameter. Due to the taper section inside the Hyperion’s mount you engage about 0.380 inches of muzzle threads rather than about 0.495 inches as you would on a suppressor without an internal taper, but that this sufficient for nearly every use. The thread adapters are handy regardless, as they bring the locking and sealing benefits of the taper to a square shoulder barrel (suggested to thread locker the adapter to the barrel), and they also allow the use of the suppressor on a skinny barrel that lacks a sufficient shoulder, because the muzzle of the barrel is designed to bottom out inside of the thread adapter.]

The thread adapters also encompass a small compensator that diffuses gases much more rapidly upon entering the Hyperion. truly, given their diminutive dimension they work more advantageous as stand-by myself muzzle compensators than you’d likely expect. not that Hyperion house owners are more likely to ever shoot unsuppressed.

near the bottom of the thread adapter is a neat looking wrench flat feature that will settle for a deep socket, field wrench, adjustable wrench, or might be even 12-point wrench. It’s the identical measurement as the wrench flats on the bottom of the Hyperion and Hyperion k.

If I even have any criticism about these CGS suppressors, it’s the further 0.8 inches of size that’s delivered to the desk by means of the thread adapters. each millimeter is quintessential to make this adapter feature, however I’m not so enamored through a tapered muzzle that I’d always select the additional length over a suppressor designed for a typical barrel with square shoulder. The taper is more suitable at offering a full gasoline seal and fighting the suppressor from coming loose, I’m just no longer certain it’s 0.8 inches improved, ya recognize?

obviously the best possible case situation right here is the usage of the CGS Hyperion on a tapered shoulder barrel and forgoing the further element and its extra size. That noted, the 1/2×28-threaded adapter is a superb way to run a .30 cal suppressor on a 5.fifty six or different, smaller-than-.30-caliber firearm with 1/2×28 threads.

Now all this mentioned, you can run the Hyperion FS or Hyperion ok on a square-shouldered barrel. You’ll get about three and three/4 rotations price of thread engagement before it’s tight. here’s ample to use (primarily for a confined firing agenda, such as when searching), nevertheless it isn’t foremost. put in on the Hyperion Thread Adapter there’s about 7 rotations of the suppressor earlier than it’s tight.

[EDIT: again, CGS contacted us to state that the suppressors tested here have a slightly different mount design than the production ones, which allow for more thread engagement (~0.380 inches of engagement, to be precise) on a standard, square-shouldered barrel and that they are perfectly well-suited to being run on a square-shouldered barrel as long as the shoulder is at least 0.735 inches in diameter. If smaller, use a Hyperion Thread Adapter.]

both of the brand new Hyperions ship with a low-profile front end cap. This front cap seals off the coaxial, outer circulation course gases.

A vented entrance end cap could be attainable quickly and, as you’ve guessed, it’s going to vent those outer move gases right out the front of the suppressor. This form of reduce backpressure, “movement-through” suppressor fashion may be preferable on a semi-automated firearm where gasoline and noise out the ejection port is every bit as much of a priority as it is from the muzzle.

Jeremy S. for TTAG

truly, enabling greater force venting on the muzzle of a suppressed, semi-automated firearm will frequently decrease the quantity level skilled on the shooter’s ears, besides the fact that it will boost the extent level on the muzzle of the gun. On a manual motion firearm, youngsters, the strong end cap is nearly certainly going to deliver extra sound suppression far and wide.

those radial holes hidden by the entrance cap of the Hyperion trace on the complicated geometry interior. The Hyperion’s coaxial outer stream path is akin to what’s considered within the cutaway drawing of CGS’s first DMLS suppressor, the Helios, considered above (and during this patent). A version of this has all the time existed in the Hyperion, but the 3D printing manner has allowed for some cool new hints and fuel pathways to take form.

in all probability essentially the most critical function — as a minimum as far as i will tell and am aware of — is how the coaxial outer stream merges returned with the main axial circulate (the gas happening the bore) about midway down the suppressor. I haven’t any concept if the okay continues this merge function at about the equal ~midway aspect alongside its length, or if it merges near its front cap and is simply identical to the massive taste up to that element within the printing process.

A 12-inch 6.5 Creedmoor probably isn’t the supposed host for the short little Hyperion okay, but I figured why not throw it correct into the deep conclusion and notice what it’s able to on this Black Collar arms Pork Sword Pistol.

Tone changed into deep, recoil reduction become top notch, and volume degree was touching up against the point of soreness. I’d run the k on this setup for searching, most likely, after I’d predict to carry the gun for hours and hours and fire it seemingly as soon as if all goes to devise. For practice and sighting in, I’d rock easy ear insurance policy.

again though, this is a short barrel firing a cartridge that arguably doesn’t suppress fairly as properly as .308 Winchester does inside the same barrel length.

The 1.75-inch diameter of the Hyperion didn’t fit under my handguard, which best clears 1.5-ish-inch silencers. I eliminated the handguard for checking out. (Jeremy S. for TTAG)

On my 8.3-inch 300 Blackout, the Hyperion k became really marvelous for its dimension. I felt like the noise from the ejection port and from the action biking changed into simply as loud as the gunshots themselves.

at the shooter’s ear, this wouldn’t be a shock with a decent suppressor. what is a shock is simply how quiet the okay is regardless of its short 6.3-inch length and light 10.2-ounce weight. Most “decent suppressors” with this level of sound suppression performance are going to be as a minimum 8 inches lengthy.

All of this become borne out lately with the aid of PEW Science in their Sound Signature overview of the Hyperion ok. by way of example, the Hyperion okay’s Suppression rating on the muzzle is set forty two% greater than that of the Q Trash Panda (which is longer and heavier than the Hyperion k, and which i like plenty). Heck, the okay is barely about 10% shy of matching the Suppression ranking of the SilencerCo Omega-300 and handily beats out the Rugged Radiant in its long configuration.

this is just uncooked sound suppression, mind you, and there are lots of other crucial considerations when determining a suppressor, but suffice it to say that the Hyperion k packs a great deal of noise discount into a compact, light-weight kit.

Switching over to the total-length Hyperion, which is a 9.5-inch-lengthy silencer, and we’re now into the realm of “quietest .30 cal silencer available on the market” ranges of sound suppression. The usual Hyperion, from everything I saw, examine, and experienced in my view, turned into probably the quietest .30 caliber suppressor out there, and it has now been crushed through the new, “3D printed” version proven here.

despite the vast length, the Hyperion FS weighs in at most effective 15.6 oz. It’s an inch longer however just over an oz lighter than my useless Air Sandman-Ti, which I even have at all times regarded a really quiet, pleasing-sounding, excellent-notch suppressor. but the Hyperion completely crushes it on sound discount. on the ear or on the muzzle, it’s completely an outlier available in the market in only how incredibly quiet it’s. For solid evaluation information, I as soon as once more imply you head over to PEW Science’s test results.

back to the 12-inch Pork Sword Pistol launching 120 grain 6.5 Creedmoor slugs downrange at about 2,450 FPS, the Hyperion makes this a most pleasant experience. I consider like extra noise came returned at me from the berm 25 yards downrange than from the gun. I’ve shot suppressors with a deeper tone, however holy heck is the CGS Hyperion quiet.

Jeremy S. for TTAG

On my 300 Blackout SBR (which I apparently left out to photo with the Hyperion FS attached), quiet doesn’t even start to describe it. in all probability “silencer” is coming near a legitimately descriptive time period right here when taking pictures subsonic ammo.

If not for the motion noise, we’re truly scratching up towards that “Hollywood quiet” kind of condition. All hyperbole apart, between the noise made by the motion — specifically the bolt clanging lower back into battery — and the sound of the bullet hitting the berm i used to be virtually unable to listen to the gunshot itself. CGS community’s new giant Hyperion mated to a 300 BLK taking pictures subs is foolish, ridiculously quiet.

due to that 1/2×28 thread adapter i was also capable of verify both the Hyperion FS and Hyperion ok on an AR-15 firing standard .223 Remington ammo. And by “AR-15” I suggest that opt for-hearth laptop gun I made on the low-cost-o polymer decrease. So, sure, the Hyperions bought a quick, full-auto workout. CGS stated I should still are attempting to preserve ’em under 800 levels but, otherwise, get at it.

So get at it I did, and the outcomes had been notable. Most .30 cal suppressors do a decent job on 5.56 / .223, and the Hyperions did first rate and then some. i used to be happy by the shortcoming of gasoline to the face and, while i used to be donning ear plugs for this bit of checking out, I might hear adequate to appreciate that this setup become quieter than with the previous two .30 cal cans I shot on this same 14.5-inch gun with this same ammo.

With a patented core and baffle design and DMLS titanium construction, the new CGS Hyperion and Hyperion k are arguably essentially the most advanced silencers on the market these days. and because of the work being finished with the aid of PEW Science, we comprehend the Hyperion is the quietest .30 cal suppressor they’ve ever tested — by using a match margin — and that i suspect it’s the quietest available, length. We’ve additionally viewed that the Hyperion k is punching neatly out of its measurement and weight class.

whereas I’m split on the choice of mounting vogue, it’s a neatly-designed, solid device that enables for use on every kind of muzzles (including on quite simply shoulderless muzzles like on the SCAR or Tavor with the use of a Hyperion Thread Adapter) and offers a straightforward technique to run this .30 cal can on a 1/2×28 barrel.

generally speaking I’d opt for these now-business-typical 1.375×24 mount threads for use with all sorts of distinct mounting techniques, however within the case of the Hyperion the coaxial outer circulate geometry starts inside the base of the suppressor and it just wouldn’t work with a removable base device that accepts other mounts. CGS’ mount design provides solid utility and it’s a superb solution, taking the taper design to the next degree with the aid of offering thread adapters for rectangular shouldered barrels.

MSRP is really on the high conclusion of the market, but it surely’s difficult to argue with the efficiency of the CGS Hyperions and the capability to swap conclusion caps to conveniently tune the suppressors to the host firearm’s fuel stream wants. now not to mention the very slick, S-Line conclude that forestalls carbon build-up and raises durability.

scores (out of five stars):

Utility  * * * *
I’m compelled to knock a celebrity off the Hyperion’s score right here, because now not going with that 1-3/eight×24 normal mounting dimension always capacity limiting dozens of incredible mounting options from use. however, the Hyperion nonetheless quotes above common because of its means to smoothly transition between rectangular shoulder and taper shoulder barrels and between 5/8×24 and 1/2×28 threads (and on barrels that comfortably lack any shoulder) with using the Hyperion Thread Adapters. The Hyperions also rating aspects for multiple front end cap designs that exchange the performance of the gas flow inside the suppressor, allowing the end consumer to regulate for the wants of a guide motion vs. a semi-automated firearm.

kind ingredient  * * * * 
the brand new CGS Hyperion and Hyperion okay are respectable looking silencers, certainly. The deepest, darkest, richest jet black of the S-Line and/or DLC finish is marvelous. I’m knocking off a celebrity for the extra size and the long, skinny mount look that the thread adapters bring to the equation, even though. They’re not obligatory in many cases, of path, and helpful in different instances, I simply hope they didn’t add almost an inch to the entire length. (creation thread adapters are black to in shape the suppressors, by the way)

Suppression  * * * * *
The CGS Hyperion FS is literally the quietest .30 caliber silencer in the marketplace, and the Hyperion k truly outperforms for its size.

standard  * * * * 1/2
if you’re in the hunt for the ultimate sound suppression attainable, the Hyperion is a five-megastar silencer in reality, in anyway. Nothing beats it and it probably isn’t even in particular shut. eventually I’m ranking the Hyperions at 4-and-a-half stars, although, essentially as a result of the barrier to entry that the high MSRP goes to give for loads of folks. They’re magnificent suppressors that can also be put to make use of on all types of distinct host firearms — literally anything else firing a 0.308-inch or smaller projectile, effortlessly — and that i don’t for a 2nd believe that CGS’ MSRP is unfair or out of line, however damn it’s nonetheless loads of skrilla. I’m additionally not in my view convinced that the taper mount is the optimal alternative, however CGS has done a really respectable job making it beneficial and near-everyday.
