When maximum .30 cal sound suppression is your goal, it's hard to do better than the Hyperion series from CGS. The titanium construction prevents the cumbersome weight issues that often come with cans which prioritize sound-suppression above all else. Additionally, the internal coating mitigates the sparking issues seen in many other titanium silencers. With these advantages, the question becomes one of optimization: do you choose the top-tier noise reduction of the full length CGS Hyperion, or go high-speed and low drag with the lighter and shorter CGS Hyperion K?
Both suppressors are built from monolithic DMLS Grade 5 titanium, finished with CGS’s internal S-Line coating to reduce fouling and an external PVD finish for durability. But in the matchup between Hyperion vs Hyperion K, the question comes down to priority of features. Do you want what has been referred to as the quietest .30 cal suppressor on the market or you need a substantially shorter and lighter option that is slightly louder?
Our guide will help you get a handle on which suppressor is best for your needs.
Both the CGS Hyperion and CGS Hyperion K are built using direct metal laser sintering (DMLS), a 3D-printing process that produces monolithic (i.e. single-piece) titanium structures. The parts are heat-treated to give the cans an excellent strength-to-weight ratio. Inside, CGS applies an S-Line coating (low-friction boron nitride) to reduce fouling buildup and prevent sparking, while shallow taper joints in the mount design promote alignment and retention.
CGS front caps play a major role in tuning. Both suppressors ship with the Low Profile Front Cap, which emphasizes maximum suppression. Optional CGS Hyperion vented caps shift performance toward lower back pressure and reduced gas to face at the cost of reduced projectile velocity. This allows users to tailor the can for suppressed platforms without major host modifications.
Independent testing positions the CGS Hyperion among the quietest .30-cal suppressors available, especially on bolt-action platforms. The tradeoff is relatively higher back pressure in semi-auto use, which can lead to increased gas to face (though ported caps can mitigate this). The CGS Hyperion K is shorter and trends louder at the muzzle but produces less back pressure, making it a better fit for semi-auto rifles where shooter comfort and maneuverability is a priority. Actual performance varies by host, barrel length, and ammunition. Though earlier models were not recommended for full auto use, modern specimens are safely capable of automatic fire.
The CGS Hyperion’s 9.5 in. body makes it well suited to precision rifles, hunting setups, or semi-autos where maximum suppression and tone are priorities. Despite its stellar sound suppression, its 15.1 oz weight means it is lighter than many of its steel-bodied competitors.
The CGS Hyperion K trims about 3 inches in length and saves roughly 4.5 ounces, making it easier to carry in the field or run on compact carbines. Its shorter profile also helps preserve ergonomics on rifles without becoming front-heavy.

Both suppressors use CGS’s 25-degree tapered direct-thread mount cut for 5/8×24. This system improves alignment and gas seal compared to flat-shoulder threads. If your barrel has a 90-degree shoulder and measures under 0.735 in. outside diameter (OD), you will need the hyperion thread adapter to ensure proper fitment. As with any suppressor, confirm bore alignment before firing.
Every suppressor ships with the titanium core and Low Profile Front Cap. Both models feature an S-Line internal coating and PVD external finish, which provides both corrosion resistance and a professional look. Optional vented caps and the Hyperion Thread Adapter are available separately.
