GENERAL OVERVIEW
The Helios QD Ti is based on the Helios QD, which is a shorter variant of CGS Hyperion Technology utilizing 1.375x24
pattern QD mount compatibility. The Helios QD, which this titanium variant is based on, was made for left handed shooters
to reduce/eliminate toxic gas in the face depending on the host firearm and was originally made for a 10.4” select fire 5.56
carbine and similar hosts such as the MK18 as well as for the M249, MK46, and variants. In some cases, the Helios QD Ti
is quieter than some other companies' fullsize rifle silencers even though the Helios QD Ti is only 6.58" added length in its
default direct thread state. As most people will never need a heavy duty silencer for extreme hard use with short barrel
rifles, machine guns, and belt feds, the Helios QD Ti will fit the bill for the vast majority of peoples realistic, practical uses.
The Helios QD Ti is built as a lightweight, and the first of its type dual function, 5.56mm silencer that just happens to have
a bore large enough to pass a 7.62mm projectile. It's a lightweight 5.56 silencer first and foremost, but with the balancing
act to get it where we wanted for sound at the ear and muzzle, we settled on a bore diameter that just happens to fit
7.62mm projectiles. Using the larger bore on a 5.56mm silencer helps achieve better sound at the ear on some 5.56mm
and similar semi auto hosts. The .355-.375” bore diameter tapering larger going forward also helps with unstable 5.56mm
and similar, basically eliminating the potential for strikes. The rear socket is modular, so you can use it as a direct thread
silencer or you can use it with any 1.375x24 pattern QD mount. All CGS rifle silencers at the time of this writing are
classified as precision rifle silencers due to their symmetrical design. CGS rifle silencers have very minimal POI shift, if
even present, and is often at the 6 o’clock area. Repeatability is excellent due to symmetrical design and concentricity
throughout the suppressor.
The CGS Helios QD Ti is limited to barrels of 10” or longer with 5.56 and similar such as 5.45. Currently everything
else just has to properly stabilize the projectile, such as using a 1:5 twist rate on 5.5” 300 Blackout subsonic. The Helios
QD Ti has a temperature limit of ~850 deg F, and once reaching this temperature band it should be allowed to cool
down. This is because, regardless of who makes a titanium silencer, titanium has inherent material properties which make
it more reactive and more rapidly susceptible to particle erosion past this temperature limit. ~850 deg F is around three full
auto magazines out of a 10.5”5.56 host firearm. Most people will never come close to reaching this temperature which is
why the Helios QD Ti is beyond suitable for most people. Stuff such as carbine classes and normal shooting is never going
to be an issue with this silencer. And in the future other accessories will be available which will further enhance the
capabilities of the Helios QD Ti.
The CGS Helios QD Ti comes with:
1) Helios QD Ti Core
2) 5/8 x 24 TPI Direct Thread Mount
3) 1/2 x 28 TPI Direct Thread Mount
4) Solid Low Profile Front Cap, Hex, Flash Hider, Standard
5) Vented Low Profile Front Cap, Hex, Flash Hider, Standard
6) QD Adapter Mount for 1.375 x 24 TPI pattern QDs from various companies
7) Hook Wrench for QD adapter (various other companies hook wrench products may be used if they fit)
8) SKB Hard Case for all components
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 which cause 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 core 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 the weld will be very 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.
The Hyperion VCD (Variable Core Diameter) 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 downstream. This also helps
reduce thermal signature as well as IR glow under nightvision. Simplicity in design eliminates unnecessary complexity
within the silencer. CGS titanium silencers also have a proprietary heat treatment applied which further increases strength
and hardness of the silencer core. All CGS rifle silencers are internally coated with hexagonal boron nitride (HBN, S-Line)
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.
It is a myth that rifle silencers “self-clean”regardless of who makes the silencer (NOTE A). The internal coating also
limits/eliminates titanium white sparking depending on cartridge and barrel length. Titanium white sparking is a separate
