The HELIOS QD presents a compact and efficient solution to rifle noise reduction, specifically tailored for 5.56mm rifles and carbines. With CGS Suppressors introducing their patented “Varying Core Diameter” technology, the firearms industry witnesses an unprecedented innovation. This ground-breaking design not only achieves optimal sound reduction relative to its size but also eliminates muzzle flash, ensuring consistent, minimal, and repeatable impact shift. By employing a taper interface between the muzzle device and the suppressor, we eliminate carbon lock on the threads while maintaining superior performance.
