Dead Air Sierra 5 W/ KeyMo

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. 

Highlights:

• BAFFLE GEOMETRY AND DESIGN: Optimized specifically for high-performance out of the 5.56 platform in sound and flash suppression, while maintaining a low blowback, short-pressure impulse.
• STELLITE BAFFLES: Industry leader in super high strength and erosion resistance at high temperatures.
• FULLY-WELDED CONSTRUCTION: Full penetration laser welding ensures a robust and solid monolithic core structure. The core is then welded to the outer tube for additional strength and durability.
• STAINLESS KNURLED OUTER TUBE CONSTRUCTION: The outer tube is knurled to provide a strong purchase for securing and removing the silencer. It also serves extremely well at securing heat-protective wraps.
• MODULARITY OF THE 1.375-24 “HUB” SOCKET: The modularity of the HUB socket allows for adapters to easily be swapped out. This includes Xeno, KeyMo, and direct thread.
• FLASH HIDER FRONT CAP: Aids in excellent visual signature reduction
• HEAVY LUG TOOL FEATURES: Allows for securely tightening and loosening adapters with included tools.
• FRONT CAP SOCKET: The Sierra-5 can accept the Sandman E-Brake and all R-Series front caps. In the event of an endcap strike, you can change the cap without having to send the whole silencer in for warranty.
