Dead Air Silencers Sierra-5 Suppressor

Using a suppressor on your gun protects your hearing and also the hearing of anyone around you. And if you’re a hunter, having a suppressed rifle is fantastic because it’s far less likely to scare off the game in the area. If the 5.56 NATO is your preferred platform, the Dead Air Silencers Sierra-5 suppressor is worth a closer look to drop the decibels produced by live fire.

Mike Pappas, Dead Air’s co-founder, made the following statement about the Sierra-5:

We’ve been working on this for a while. We’ve designed the Sierra-5 from the ground up to be a dedicated 5.56 suppressor. It sounds amazing. It’s lightweight and has uncompromising durability for the professional. We really feel this combination alone will appeal to hunters and tactical shooters alike.

The Dead Air Silencers Sierra-5 is available as either the Sierra-5 Xeno or the Sierra-5 KeyMo. The Xeno was designed to be compatible with the associated mounting system and the KeyMo works with KeyMo adapters. Both models are produced to Dead Air Silencer’s exacting specifications.

Dead Air Silencer also released details about the Sierra-5 suppressor:

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 Stellite baffles wrapped in a stainless outer tube, Sierra-5 is the last 5.56 suppressor you’ll need.
