The CGS Helios QD Inconel Silencer is built with Direct Metal Laser Sintering (DMLS), creating a suppressor made of Inconel 718. This construction method avoids the weaknesses associated with welds by forming a complex gas flow path. This suppressor incorporates specific patented technology known as “Varying Core Diameter”, providing sound reduction and flash signature elimination. The taper interface between the suppressor and the muzzle device helps reduce carbon locking of muzzle device threads (Source).
With 5.56mm rifles, the Helios QD Kit is extremely low back pressure due to the generous bore. This also allows it to be used on larger calibers, all the way up to 300 Norma mag. The "Bravo" or "Omega" mounting thread pitch (1.375x24) accepts a number of mounting solutions. While it comes with both 1/2x28 and 5/8x24 direct thread mounts, it can utilize almost every mounting system currently available. The front caps are interchangeable as well.
The Helios QD is designed with a wide .36 bore, resulting in reduced back pressure and muzzle flash. This larger bore makes it adaptable to be used with various rifle calibers, even as large as .300 Norma Magnum. The user is given the option of two included end-caps; one solid end-cap for greater sound reduction and a vented end-cap for reducing blowback, a significant feature for left-handed shooters or for systems susceptible to over-gassing.
The Helios QD is designed to withstand demanding conditions and has a full-auto rating, without any barrel length restrictions (Source).
Despite its robust construction, the Helios QD is compact, with a diameter of 1.75 inches and it adds an extra 4.9 inches to any muzzle device. All the components of Helios QD are designed and manufactured in the USA.
Pew Science's analysis shows that the Helios QD, when used with Federal XM193 on a 10.3-inch barrel MK18, achieved a Suppression Rating of 24.5 with its vented end-cap, and a rating of 27.1 with its solid endcap (Source). Due to its significant over-bore for the 5.56x45mm platform along, as well as its unique internal geometry, Helios QD's sound suppression performance can be affective when used with 5.56x45mm short barrel weapons (Source).
Overall, the CGS Helios QD Inconel Silencer incorporates the key attributes of durability, sound reduction, and compatibility with multiple calibers. Its unique design elements, including the "Varying Core Diameter" technology and interchangeable end caps, offer users an effective solution that balances versatility and durability. The Helios QD comes as a kit! Why a kit? The Helios has so many options, and the kit is a quality case, and includes a 1/2x28 threaded rear cap, a 5/8x24 threaded rear cap, interchangeable sealed end caps, and an adapter ring threaded in 1.375x24 for use with Hub adapters. Helios QD is almost unrivaled when it comes to sound suppression and durability.

Buying and shipping through Charlie’s is easy, but there is some information you need to know. This item must ship to FFL holder. No civilian exceptions.
1) Check your state laws to make sure the federally regulated item you want to purchase is legal in your state.
2) Find your FFL… Have your dealer send us a copy of their FFL and SOT to Charlie’s (Make them earn their fee!). Not every FFL is a SOT or Class 2 / Class 3 dealer.
3) Be patient! You should hear from our compliance department within 3-4 business days. If not, feel free to reach out for a status update.
That’s it! We try to make this process as simple as possible for our customers. Please click the “Buying a Firearm” tab at the top of this page for more information.
THIS IS A SERIALIZED ITEM. It must ship to a Federal Firearms License holder. No civilian exceptions.
Buying and shipping through Charlie’s is easy, but there is some information you need to know. Only a federally licensed firearms dealer may receive a firearm or federally regulated serialized item (like a receiver or suppressor). We cannot ship these items directly to you. Please follow these steps to process your transaction:
1) Check your state laws to make sure the federally regulated item you want to purchase is legal in your state. Your FFL dealer should be able to give you all of the necessary information regarding your state specific laws. But, if we ship to your FFL, and there is a legal issue, we cannot accept a return. So please make sure that you know and follow your local and state laws.
2) A quick google search will show you what Federal Firearms Licensed (FFL) dealers are in your area. When you are ready to purchase, contact the FFL dealer you would like to use and get their shipping address. During the check-out, put YOUR address in the “billing” section and the FFL DEALER’S address in the “shipping” section. If you don’t know your FFLs address, that’s okay. You can send the information later.
3) After check out, make sure to contact your FFL dealer to ensure they will receive your shipment for you (most do this for a small fee, but you should always double check).
4) Have your dealer send us a copy of their FFL to FFL@CharliesCustomClones.com. Charlie’s does not reach to your FFL (MAKE THEM EARN THEIR FEE!!!)
5) Be patient! In order to ensure we remain compliant with all federal laws, our compliance department is kept separate from our sales and operations team. Please allow a few days for our compliance officer to verify all of your dealer’s documents and ensure all federal laws are being observed. You should hear from our compliance department within 3-4 business days. If not, feel free to reach out for a status update.
That’s it! We try to make this process as simple as possible for our customers, but if you are unfamiliar the process or have any other questions, please visit our How to Buy a Suppressor page for more details.
