Introducing the Dead Air Sierra-5, the all-new 5.56 silencer from Dead Air. From the beginning, our mission has been to take 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.

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, the Sierra-5 boasts a clean and utilitarian knurled design that provides both function and form.
