Dead Air Sierra 5 with Keymo Adapt

Sierra Suppressor – Dead Air 5.56 KeyMo

The Sierra suppressor from Dead Air Silencers is a compact, high-performance 5.56 silencer engineered for reliability, durability, and superior sound reduction. Shooters can choose between KeyMo and Xeno mounting options, depending on their preference. The KeyMo configuration measures 6.27 inches in length and weighs 15.4 ounces, making it ideal for lightweight rifle builds.

Dead Air designed the Sierra suppressor with laser-welded stellite baffles and a 17-4 PH stainless steel body, ensuring maximum strength and optimal performance with 5.56 or .223 ammunition. Its high-temperature Cerakote finish protects the body, while the nitride-treated adapter and mount resist corrosion, providing long-lasting durability.

The suppressor works seamlessly with Dead Air R-series front caps, including the Sandman E-Brake. Shooters can easily remove the front cap flash hider and attach any compatible Dead Air front cap. The Sierra suppressor excels in both sound and flash suppression, making it perfect for range use, training, or tactical applications.

Compact yet rugged, the Sierra suppressor delivers exceptional maneuverability without compromising durability. It is full-auto rated, offering one of the toughest 5.56 silencers available. Dead Air’s dedication to quality and innovation is evident, as the Sierra joins a lineup that earned five spots among the best 7.62 suppressors of 2021 at Silencer Shop.
