Product description

Dead Air - Sierra 5 - KeyMo

You may be familiar with the legendary Sandman and Nomad suppressors, manufactured by the renowned innovators at Dead Air Silencers. They’ve raised the bar on their ‘No Quarter’ philosophy with the Dead Air Sierra 5. The Sierra 5 is a compact, durable suppressor available in one of two mounting options: KeyMo mount and Xeno mount. The KeyMo options measures 6.27” long and weighs 15.4 oz. Are Dead Air suppressors any good? Yes, the Dead Air Sierra 5 is engineered with high-quality, laser-welded stellite baffles that are optimized specifically for 5.56 or .223 ammo.

You can easily remove the front cap flash hider of the Sierra 5 and replace it with any Dead Air R-series front cap (such as the Sandman E-Brake). The Sierra 5 is purpose-built to give you one of the best performing 5.56 suppressors across various settings. Are Dead Air Silencers full auto rated? Yes, the Sierra 5 is full-auto rated, ensuring you have one of the toughest suppressors Dead Air can produce.


You’ll have a suppressor that is maneuverable and highly durable with the Sierra 5. This dedicated 5.56 suppressor will give you the best of both worlds in sound and flash suppression while remaining compact. When you choose the Sierra 5, you are partnering with a manufacturer that achieved 5 spots on the best 7.62 suppressors of 2021 at Silencer Shop.
