Free NFA Gun Trust
- We offer a free NFA Gun Trust (a $250 value) to all customers which essentially establishes a joint ownership scenario in which you can legally share your silencer with designated others (as well as determining who will inherit your silencer). This lets others use your silencer.
- We do all the ATF paperwork which helps ensure you completed the gun trust correctly so ATF does not reject. We have completed over 15,000 silencer to gun trust transfers and counting! Learn More

Description and Specs
Built to take a beating and keep performing, the Dead Air Sierra 5 is a full-auto-rated 5.56 suppressor designed for relentless use. Crafted with a fully welded Stellite® baffle core and a durable stainless steel tube, this compact powerhouse is ready for anything you throw at it. Whether you're running it hard on duty, at the range, or in the field, the Sierra 5 delivers exceptional sound suppression while standing up to extreme conditions. Its optimized baffle design reduces backpressure and flash signature, ensuring top-tier performance when it matters most.
The Sierra 5 is available in two rock-solid mounting options: the Sierra 5 KeyMo, which utilizes Dead Air’s KeyMo system for fast, secure attachment to KeyMo muzzle devices, and the Sierra 5 Xeno, which features the Xeno mount for a lightweight, minimalist setup. No matter which option you choose, you’re getting a suppressor built to withstand hard use while providing reliable, repeatable performance. When durability, performance, and modularity matter, the Dead Air Sierra 5 is ready to go to work.
