SIERRA 5 XENO 5.56MM RIFLE SUPPRESSOR

From the beginning, Dead Air’s 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. Dead Air is not cutting costs or decreasing lifespan by using stainless steel baffles. They 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 their goal when developing the Sierra 5. Frankly, if you don’t get the Sierra 5 red hot each time you shoot it they 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 the Xeno mounting system.

Featuring the proven winning combination of welded Cobalt 6 baffles wrapped in a stainless outer tube, Sierra 5 is the last 5.56 suppressor you’ll need.

The Sierra 5 Xeno includes a 1/2-28 Xeno flash hider and a Xeno adapter.

FEATURES:

  • Flash hider front cap – The included flash hider front cap aids in excellent visual signature reduction.
  • Interchangeable front caps – The Sierra 5 is compatible with all of the R-Series front caps, including the E-Brake.
  • Fully-welded construction – All Cobalt 6 baffles and full penetration laser welding ensures a robust and solid monolithic core structure. Then welded to the outer tube for additional strength and durability. The Sierra 5 is optimized specifically for high-performance out of the 5.56 platform in sound and flash suppression, while maintaining a low blowback, short pressure impulse.
  • Mounting modularity – The Sierra 5 XM ships with the complete Xeno system (adapter and flash hider). But thanks to the 1.375-28″ HUB socket you can change your mind without regret. The Sierra 5 features a small hole drilled through the blast chamber making it possible to pin & weld your adapter or insert to the suppressor. (Ships with 1/2-28 Xeno flash hider and Xeno adapter)
  • Utilitarian design – The outer tube is knurled to provide a strong purchase for securing and removing the silencer. It also serves extremely well in securing heat-protective wraps. The Sierra 5 also boasts heavy lug tooling features allowing for secure tightening and loosening adapters with included tools.

Frequently Asked Questions

Are these brass cases and reloading components factory-new or once-fired? +

We stock both premium factory-new components and high-quality once-fired brass. Please check the specific product listing title and description carefully; once-fired brass is fully inspected, but we always recommend resizing and inspecting prior to priming and powder charging.

Will this case trimmer gauge or die set work with my progressive press setup? +

Our standard reloading dies and case length trimmer accessories utilize industry-standard threads (typically 7/8"-14) compatible with major single-stage, turret, and progressive presses like RCBS, Hornady, Lee Precision, and Dillon. Caliber-specific trim gauges must match your exact brass caliber.

Do you enforce shipping restrictions on powder, primers, or live ammunition? +

Yes. Non-hazardous reloading equipment (dies, case length trimmers, gauges, and unprimed brass) ships via standard ground carriers with no extra fees. Any orders containing smokeless powders or primers will incur standard federal HazMat handling fees and cannot be shipped via air transportation.

How can I track my shipment to ensure delivery safety? +

Precision reloading gear is valuable, so all orders are shipped with tracking enabled. As soon as your package is dispatched from our inventory warehouse, a tracking number will be emailed to you. You can monitor your shipment directly on our Track Order page using your unique Order ID.

Can I return precision measuring tools or die components if they don’t fit? +

We accept returns on unused, unaltered tools, case preparation equipment, and unopened component boxes within 30 days of item delivery. Due to safety and strict quality control on the reloading bench, we absolutely cannot accept returns on opened packs of primers, smokeless powder, or processed brass casings.
