Dead Air SIERRA5KM Sierra-5: A KeyMo-Ready Suppressor with Xeno Mount or KeyMo Mount The Dead Air Sierra-5 suppressor is a new offering for 2022 that boasts a perfect balance of sound and flash reduction, all while maintaining a compact profile with minimal weight. This suppressor is designed for hard, professional use, and is rated for full-auto fire. The ultra-durable, fully welded construction features an outer tube made from premium stainless steel, with knurling to provide a strong grip for securing and removing the suppressor or for use with heat-protective wraps. Inside the Sierra-5, you'll find all Stellite baffles with full penetration laser welding, ensuring a solid and robust monolithic core structure. The core is then welded to the outer tube for added strength and durability. This configuration not only greatly reduces sound and flash signature but also provides a low blowback, short-pressure impulse for maximum control during firing. The Sierra-5 suppressor also features a HUB socket, allowing the suppressor to be easily configured to the user’s specific needs. Additionally, a small hole drilled through the blast chamber makes it possible to pin and weld your adapter or insert to the suppressor, providing even greater customization. For added convenience, the Sierra-5 suppressor ships with either a Xeno mount or a KeyMo mount, depending on your preference. Both mounts provide a secure and easy-to-use attachment method, ensuring that the suppressor stays in place even during rigorous use. Overall, the Sierra-5 suppressor is a high-quality and durable choice for anyone seeking professional-grade sound and flash reduction in a compact and lightweight package.
