Who said big things don’t come in small packages? The CGS Helios DT 5.56 Suppressor 1/2-38 (.223) proves otherwise.


The CGS Helios DT has a 10″ minimum barrel length for 5.56.


The CGS HELIOS DT signature suppressors are made specifically for host weapons firing 5.56mm projectiles. Like all CGS rifle suppressors, the HELIOS DT features the first of its type dual functionality and incorporates the Variable Core Diameter (VCD Technology) first pioneered by the CGS Hyperion. The patented proprietary technology unique to CGS Group LLC rifle silencers is unlike anything the firearms industry has ever seen before. This unique design allows for peak sound reduction and extreme reduction in flash signature as well as minimal and repeatable point of impact shift. This suppressor is available in a 1/2×28 direct thread mount. The HELIOS DT is available in 6AL4V (Grade 5) titanium and is an excellent precision rifle suppressor displaying incredible suppression, light weight, and a very minimal 6 o’clock vertical on/off fleet POI shift.


The HELIOS DT core is made of Direct Metal Laser Sintered (DMLS – 3D printed) heat treated 6AL4V (Grade 5) titanium. 6AL4V titanium is used to significantly reduce system weight while maintaining high strength. The DMLS manufacturing process was chosen as it allows for construction with less potential points of failure, lighter construction, improved sound reduction, and increased durability. The VCD Technology increases sound performance significantly.


The CGS Helios DT  is a 1/2-28 direct thread, and will ship in an SKB hard case.
