Dead Air Armament Sierra 5 Suppressor - Keymount

Introducing the all-new 5.56 silencer from Dead Air Silencers. From the beginning, their 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. They are not cutting costs or decreasing lifespan by using stainless steel baffles. They 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 their goal when developing the Sierra-5. Frankly, if you don’t get the Sierra-5 red hot each time you shoot it they 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 their 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.
