Introducing Dead Air's 5.56 silencer, the Sierra 5. Dead Air's mission has always been to give No Quarter in design, performance, and technology. The Sierra 5 takes this into account, and gives shooters everything they have been asking for in a dedicated 5.56 silencer.

Built with professionals in mind, there is no compromise to durability, flash suppression, or decibel reduction. It still maintains a small footprint, and minimal weight. As many shooters desire different types of mounting options, the Dead Air Sierra 5 is HUB compatible (1.375"x24) to accept a variety of mounts. I can be configured to the users specific needs, and is available in both Xeno and Key-Mo versions out of the box.

As with Dead Air's other hard-use silencers, it features welded Stellite baffles. The Sierra 5 is then wrapped with a stainless outer tube for extra support. Visually it is a clean, utilitarian knurled design that provides both form and function.

The Dead Air Sierra 5 is compatible with Dead Air Key-Mo (Omega), SilencerCo Omega / Hybrid ASR, Plan B by Q, and any other mounting systems that fit the SilencerCo Omega, SilencerCo Hybrid, or Energetic Armament VOX. This allows the shooter to adapt the Sierra 5 to whatever mounting system they see fit for a specific task or rifle. Additionally, the Dead Air Sierra 5 uses Sandman Front Caps, Flash Hider Front Caps and is compatible with the Dead Air E-Brake.
