Description

DEAD AIR SIERRA-5 KEY MOUNT 5.56MM SUPPRESSOR

Introducing the all-new 5.56 silencer from Dead Air Silencers. 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.

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.

Flash hider front cap

The included flash hider front cap aids in excellent visual signature reduction.

Interchangeable front caps

The Sierra-5 is compatible with all of our R-Series front caps, including our E-Brake.

Fully-welded construction

All Stellite® baffles and full penetration laser welding ensures a robust and solid monolithic core structure. Then welded to the outer tube for additional strength and durability.

The Sierra-5 is optimized specifically for high-performance out of the 5.56 platform in sound and flash suppression, while maintaining a low blowback, short pressure impulse.

Mounting modularity

The Sierra-5 KM ships with the complete KeyMo system (adapter and flash hider). But thanks to the 1.375-28″ HUB socket you can change your mind without regret.

The Sierra-5 features a small hole drilled through the blast chamber making it possible to pin & weld your adapter or insert to the suppressor.

*Ships with 1/2-28 KeyMo flash hider and KeyMo adapter

Utilitarian design

The outer tube is knurled to provide a strong purchase for securing and removing the silencer. It also serves extremely well in securing heat-protective wraps.

The Sierra-5 also boasts heavy lug tooling features allowing for secure tightening and loosening adapters with included tools.
