From the manufacturer

The CGS HELIOS QD is a short, quick attach rifle silencer designed specifically for 5.56mm rifles and carbines. The patented "Varying Core Diameter" technology unique to CGS Suppressors is unlike anything the firearms industry has ever seen before. This unique design allows for peak sound reduction for its size and elimination of the flash signature as well as consistent, minimal and repeatable point of impact shift. By using a taper interface between the muzzle device and the signature suppressor, we ensure the muzzle device threads will not carbon lock. The HELIOS QD utilizes a full DMLS 718 Inconel design for maximum strength and extreme durability. The HELIOS QD system was designed to be extremely versatile. The generous .36 bore significantly reduces back pressure and muzzle flash while also allowing the suppressor to be used with multiple calibers. The HELIOS QD comes with a 1/2x28 threaded rear cap, a 5/8x24 threaded rear cap, and an adapter ring threaded in 1.375x24 to accept a plethora of industry QD mounting solutions. The interchangeable rear caps are complimented with interchangeable front caps as well. A sealed front cap is provided for the maximum sound reduction possible. A ported front cap is included to ensure blowback mitigation for left hand shooters or for use with calibers or weapon systems that may be prone to over-gassing. The HELIOS QD is full auto rated with no barrel length restriction and will handle up to and including 300 Norma Magnum. The HELIOS QD has a lifetime warranty and due to the design of the suppressor the serial ring can be removed and welded to another core should the need ever arise. We fully warranty the HELIOS QD on the MAXIM DEFENSE PDX and MDX line of firearms in any caliber, any barrel length, and in both semi and fully automatic firing modes. Designed and manufactured in Artesia, New Mexico USA by CGS Suppressors LLC, a division of CGS Group LLC.
