SIERRA5KM

Introducing the all-new 5.56 silencer from Dead Air. From the beginning, our mission has been to take 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.

 

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 either our KeyMo or Xeno mounting system.

 

Featuring the proven winning combination of welded Stellite baffles wrapped in a stainless outer tube, the Sierra-5 boasts a clean and utilitarian knurled design that provides both function and form.

Before You Buy

Firearms & Ammunition Compliance

FFL Transfer (Firearms)

Firearms ship only to a licensed FFL dealer — never directly to a residence. The transfer process is:

  1. Choose a local FFL dealer and have them email a copy of their license to ryan@3bandedarms.com, or contact us and we’ll help coordinate.
  2. We ship the firearm to your chosen dealer once a valid FFL is on file.
  3. Complete ATF Form 4473 and pass a background check in person at the dealer.
  4. Take possession after the dealer’s approval. The dealer may charge a transfer fee.

Age Requirements

  • 21+ to purchase handguns and handgun ammunition.
  • 18+ to purchase rifles, shotguns, and rifle/shotgun ammunition.
  • A valid government-issued photo ID is required to complete any transfer.
  • Purchasers may not be prohibited persons under 18 U.S.C. § 922(g).

Ammunition

  • Age verification is required at purchase and may be required again upon delivery.
  • Ships within the United States only. Some states and cities require a permit, license, or ID — or prohibit shipment entirely.
  • We do not ship ammunition where it is restricted by state or local law.
