Dead Air Sierra-5


Dead Air Sierra-5


The ultimate 5.56 suppressor


Once we have started a transfer, we are unable to do returns on suppressors or firearms. If you have warranty issues with the product itself, we will work with you and the manufacturer to get them resolved.

If you live in UT, and use Pew Pew Solutions as your dealer, there are no transfer fees. If you live in another state, you will need to arrange for a local dealer to handle the transfer- this and any fees they may charge are the buyers responsibility.

It is the buyers responsibility to ensure they can legally own a suppressor. In general, this means: You must be at least 21 years old - You must live in a state that allows ownership - You must not have any felony convictions.

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.
