Dead Air Armament SIERRA5XM Sierra 5 Xeno Silencer 5.56 Black

From the beginning, our mission has been to give No Quarter in design, performance, and technology. The Sierra 5 stands true to that mission by giving you everything you want out of a dedicated 5.56 silencer.

This is a hard-use silencer. We are not cutting costs or decreasing lifespan by using stainless steel baffles. We are not sacrificing durability in search of saving a few ounces. The Sierra 5 is full-auto rated with no barrel length restrictions. Love or hate the knurling, it’s function over form, directly inline with our goal when developing the Sierra 5. Frankly, if you don’t get the Sierra 5 red hot each time you shoot it we might be offended.

Built for professional use, it offers the perfect balance of overall sound and flash suppression while maintaining a compact footprint and minimal weight. By utilizing HUB compatible (1.375-24”) mounting adapters, it can be configured to the end user’s specific needs and is available out of the box with either our KeyMo or Xeno mounting system.

Featuring the proven winning combination of welded Cobalt 6 baffles wrapped in a stainless outer tube, Sierra 5 is the last 5.56 suppressor you’ll need.

The Sierra 5 Xeno includes a 1/2-28 Xeno flash hider and a Xeno adapter. Check out the Sierra-5 KeyMo if you prefer a KeyMo system out of the box.
