No barrel length restrictions and full-auto rated. Need we say more? The CGS Helios QD, constructed of durable 718 Inconel and 17-4 stainless steel, is specifically designed for 5.56 mm rifles and carbines. That being said, this 7.62 silencer is bored out to .36, allowing for more versatility with calibers while also significantly reducing back pressure and muzzle flash. Because the bore is larger, there is more opportunity for the gas to move forward thro
The Helios QD comes as a kit! Why, you may ask? Because of options! With a 1/2x28ugh the baffles and out of the end of the silencer instead of causing the gas to exit through the ejection port causing undue blowback.
threaded rear cap, a 5/8×24 threaded rear cap, interchangeable sealed end caps, and an adapter ring threaded in 1.375×24 included, you’ll be spoiled for choice. As with every CGS suppressor, the Helios QD is almost unrivaled when it comes to sound suppression.

Excellent silencer. Very quiet and the interchangeably between .223 up to .338 is fantastic. I’ve shot 5.56 and 6.8 SPC with no issues. Handles rapid fire very well. Has an interchangeable cap that allows left handed shooters to avoid gas blowback. Lifetime warranty is a huge plus. Solid design.
The major negative is the muzzle device and customer service. CGS doesn’t sell additional muzzle devices. The muzzle device is a larger size which isn’t common. I haven’t been able to locates additional devices so I can install on other rifles. You are stuck with the 2 you receive 1/2 inch and 5/8 inch.
The customer service leaves something to be desired. Not very helpful. No contact number, email only and they do not provide helpful information. If you have questions, they will not directly help you (only point to user manual).

This thing is chooonky down at the end of a barrel and kinda wish I had waited for the Ti……..but I bought it to be a tank and it definitely is. Pretty much running it as a dedicated 300 can which keeps the weight nice and close in on a 7″ barrel. Excited to get it on a bolt gun here in the deer season.

The Helios QD is great. I am very impressed with its performance out of an 11.5″ SBR. It’s definitely not a cheap item, but I’m happy with my purchase.

It is an expensive can but well worth the price of admission.
Brian B –
Excellent can. If using on an AR, get a short muzzle brake set sup from YHM or Rearden. Sounds much better than direct thread.

Excellent silencer. I primarily use it for short barreled 300BLK, it’s stupid quiet and the weight keeps the muzzle under control. Sounds excellent on 5.56, .308, and 6mm ARC as well.

Extremely quiet, quality made product. I’m very pleased.
