Silencer
CGS Helios QD 5.56 Suppressor
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 5/8x24 threaded rear cap, interchangeable sealed end caps, and an adapter ring threaded in 1.375x24 included, you'll be spoiled for choice. As with every CGS suppressor, the Helios QD is almost unrivaled when it comes to sound suppression.
