Introducing the all-new 5.56 silencer from Dead Air Silencers. The Sierra-5 gives you everything you want out of a dedicated 5.56 silencer.
This is a hard-use silencer. 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 Dead Air's goal when developing the Sierra-5. 
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 Stellite® baffles wrapped in a stainless outer tube, Sierra-5 is the last 5.56 suppressor you’ll need.
The Sierra-5 KeyMo includes a 1/2-28 KeyMo flash hider and a KeyMo adapter. Check out the Sierra-5 Xeno if you prefer a Xeno system out of the box.
