Here's a prior write up with important info on the Hyperion if you haven't already seen it:
You can shoot 5.56 through a Hyperion no problem, you just need to use the 1/2x28 Hyperion Thread Adapter so you can install it on the 1/2x28 barrel. Minimum barrel length for CGS titanium rifle silencers is 10" for 5.56 and similar like 5.45.
The Hyperion is a DMLS titanium rifle silencer with a permanent 5/8x24 direct thread socket with the SIG 25 deg taper interface. It was originally designed for an 18" 260 Remington AR10 and a 6.75" 300 Blackout machine gun. While not designed for bolt guns at all, it works extremely well with them for sound reduction and long distance precision. All current commercial production CGS rifle silencers are precision rifle silencers due to the symmetrical design. All properly designed long range precision rifle silencers will have a symmetrical blast chamber/baffle, and all others that claim to be precision rifle silencers which don't, definitely should.

On a 22" bolt gun firing supersonic 6.5 Creedmoor the Hyperion's even quieter than some other silencers firing subsonic Blackout through an 8" bolt gun:

And it's very nearly the same suppression rating as the

It's also quieter firing supersonic 6.5 Creedmoor on a 22" bolt gun than shooting subsonic 9mm through the CGS MOD 9 on an HK P30L:

The additive manufacturing process we use makes our rifle silencers far stronger than other comparative rifle silencers for a few reasons. Our manufacturing process creates parts with even higher strength and hardness than billet or forgings or castings or MIM, and does so with increased material density. There are no welds so there are no welds to fail and no welds to warp causing concentricity problems along the length of the silencer. This eliminates welding issues such as welds breaking and their byproducts such as warping, entirely. The monolithic structure and lack of welds make CGS rifle silencers very strong and eliminates failures, concentricity problems, and QC issues from welds. Even if the weld looks perfectly silver on the exterior you can easily have something that looks fine on the outside but the weld won’t penetrate properly for a number of reasons such as electrical problems within the machine itself, operator error, contamination, etc, so it’ll be super weak and it won’t be caught until the weld failure occurs in the end users hands as their using it. That applies to all materials, not just titanium, and failures like that are part of why CGS no longer gets silencers welded by another silencer company.
The Hyperion VCD design itself makes the silencer stronger than any other comparative silencer by better controlling heat and pressure to prevent hot spots from forming. The first chamber is immediately vented and gas is allowed to flow around the first core and is then reintroduced to the main flow further down stream and this also helps reduce thermal signature. Simplicity in design eliminates small, complex cavities and other undesirable features. The titanium silencers also have a proprietary heat treatment applied which further increases strength and hardness. They're internally coated with hexagonal boron nitride which decreases friction, increases surface hardness, and prevents fouling from sticking in the first place which eliminates the need to clean because fouling can't easily stick to internal geometry, though they still could be cleaned if ever required. The internal coating also limits/eliminates titanium white sparking depending on cartridge and barrel length. Titanium white sparking is a separate thing from flash and can't be controlled with a flash hider. The exterior is coated with black DLC. They're also the only dual function silencers available that can be converted simply by changing out the front cap with a 7/8" wrench. This allows you to have a traditional type silencer and a flow bypass type silencer all in one simple package. With future front cap releases it'll also be adjustable across the entire spectrum of sound, flash, and gas reduction just by swapping out the front cap. No longer do you have to live with just one permanent setting on a silencer. Both front caps and rear caps are retained with shallow taper joints which helps with concentricity and cap retention as it has more grip than a square shoulder. This also makes it future proof so regardless of when new front or rear caps are made they'll always be concentric to the silencer bore.
CGS rifle silencers are also some of the very few that don't sacrifice subsonic performance to achieve supersonic performance, it excels at both without compromise. Usually rifle silencers will either be good at supersonic and mediocre at subsonic, or good at subsonic and mediocre at supersonic. This can be seen with SIG and Q silencers where they're good at subsonic suppression but don't perform with supersonic ammo anywhere near as well. Since 99% of strikes occur on the front cap, since we don't use any welds in our silencers, and since our DMLS process creates a superior product in every meaningful way there's nothing that's going to need repairing other than on extremely rare occasion the front cap which is easily sent in the mail. In over three or four years no DMLS rifle silencers have been returned for repair from military, government, or commercial customers or consultants because the root of the primary problems are eliminated.
The Hyperion VCD technology is also used in our GPMG 762 silencer made for the M240, MAG 58, MK48, etc as well as belt fed 338 Norma Magnum machine guns. Here's 1259rds fired through one on an M240:
The effectiveness of this technology can also be seen plainly in the Helios QD. It's nearly 2" shorter than a Thunderbeast Ultra 9 but it's very nearly the same suppression level and the Helios QD is just as capable of a precision long range rifle silencer as an Ultra 9, if not more so:

https://pewscience.com/sound-signature-reviews-free/sss-6-24-tbac-ultra-9-savage-308
And the Helios QD is also quieter than your Dead Air Sandman L and your Rugged Surge in it's longest config:

https://pewscience.com/sound-signature-reviews-free/sss-6-22-rugged-surge-savage-308
The titanium version of the Helios QD gets released any day in the next few weeks and weighs ~11oz, almost half of what the 718 Inconel Helios QD weighs.
PewScience is the only valid, unbiased, and accurate silencer sound testing available to consumers and everyone else including manufacturers, dealers, distributors, and YouTubers and it's the sole source of data everyone should be using and referencing for data on silencer sound. Everything else you see, for example anytime you see single peak meter data like in Silencer Shop videos or when you see any form of data from companies that sell or manufacture silencers or silencer mounts or accessories in general, is simply meaningless entertainment for the uninformed consumer/viewer being passed off as science and fact. PewScience has tested some stuff on 5.56 already, it's just not been published yet.

I also never once said my shit was scientific... I have, however, stated it was for fun and entertainment purposes only. So, yeah, if you don't like it, don't watch...But judging by how you can't let this go, I'm already living rent-free in your mind. So, I guess the hard work is done.
