Hyperion 762 and Hyperion 762 K Signature Suppressors


All CGS rifle silencers are based on what we call “Hyperion VCD Technology”. Hyperion Tech is a signature suppression system developed internally by CGS Group LLC designed to address multiple issues that have plagued rifle silencers in various ways for the past 130 years. The patented and patent pending features incorporated into CGS rifle silencers utilizing Hyperion Technology are the current state of the art for signature suppressors and there is nothing on the horizon that will surpass it any time soon.


1) The absolute best supersonic sound suppression available by a significant margin, all while not sacrificing subsonic sound suppression or blowback reduction. Before you stop reading, that is not marketing speak, that is a verifiable fact (see PewScience note below).

2) Function Changing Front Caps completely change the function of the silencer as desired by the end user. The end user can make the CGS Hyperion a “traditional” type silencer by using the Solid Front Cap (included) which is ideal for something like a bolt gun or most semi auto and select fire hosts, or the end user can make the CGS Hyperion a “flow bypass” type silencer simply by removing the existing front cap with a 7/8” wrench and replacing it with the Vented Front Cap (purchased separately). The Vented Front Cap allows excess gas within the suppressor to vent to atmosphere without further influencing the host weapon system and further preventing toxic gasses from being blown back at the shooter. In the future, different front caps will be made available such as those with longer central flash hider to improve flash elimination, and those with varying vent size and quantity, and those with flash hiding features for each peripheral vent. While “flow bypass” type silencers are nothing new, having been around since 1909 and in their current form since 1927, the convertible and adjustable function concept in CGS rifle silencers certainly takes suppressor capability to the next level and was never attempted or perfected until now. It is the best of both worlds in one simple package.

3) No first round pop.

4) Additive Manufactured (3D Printed) Core with a proprietary internal Hexagonal Boron Nitride coating to prevent the buildup of fouling an and external black DLC coating. AM allows for the elimination of failure points such as welds or machining errors and is stronger than that billet material that silencer parts are commonly machined out of, and allows for excellent concentricity throughout the suppressor.

5) CGS rifle silencers manufactured via AM use a proprietary heat treatment process which vastly improves strength of the silencer core compared to the standard heat treatment used by other manufacturers.

6) All 7.62mm CGS rifle silencers come by default with a 5/8×24 direct thread mount compatible with the SIG Sauer 25 deg taper barrel shoulder. Barrels with 90 deg shoulders must have a minimum diameter of .735” at the shoulder, however barrels under .735” diameter at the shoulder can use the CGS Hyperion Thread Adapter (sold separately) which will turn a 90 deg barrel shoulder into a 25 deg barrel shoulder and is compatible with all barrel diameters. This gives the user the retention benefit of the taper shoulder and will also allow the use of skinny barrels utilizing muzzle shoulders such as the FN SCAR 17. The Hyperion Thread Adapter is also offered in 1/2×28.

Hyperion 762:


LENGTH: 9.5”

WIDTH: 1.75”

WEIGHT: 15.1oz

MATERIAL: Grade 5 Titanium (6Al4V) – AM Core/Billet Front Cap

Hyperion 762 K:


LENGTH: 6.3”

WIDTH: 1.75”

MATERIAL: Grade 5 Titanium (6Al4V) – AM Core/Billet Front Cap

In short, the CGS Hyperion series and its CGS derivatives are the bleeding edge of signature suppression, not only for their incredible sound reduction capability but also for their useful, unique, feature rich design that solves many problems, all incorporated into one simple, strong, lightweight, quiet system.

CGS Group LLC was founded in August of 2014 with the intent to design and produce the best products available for their intended applications. Primarily known for silencers, CGS Group LLC also designed and produces the PANDORA Firing Device – a dual, independent channel, double action, striker fired, modular. mechanical initiator allowing for very safe, one-handed manipulation for explosive breaching and other explosive related activities.
