Description

Dead Air’s mission is to give No Quarter in design, performance and technology, and the Sierra 5 gives you everything you want from a dedicated 5.56 silencer. This is a hard-use can: no stainless baffles to cut cost or lifespan, no durability sacrificed to save ounces. If you do not get it red hot each time you shoot, Dead Air might be offended.

Built for professional use, it balances sound and flash suppression in a compact, light package. HUB (1.375-24) adapters let it be configured to your needs; out of the box it comes with KeyMo or Xeno (the Xeno version includes a 1/2-28 flash hider and adapter). Welded Cobalt 6 baffles in a stainless tube.

  • Caliber rating: 5.56 NATO, .224 Valkyrie (2,200 ft-lb)
  • Length: 4.87 in (no adapter) / 5.72 in with Xeno
  • Diameter: 1.5 in
  • Weight: 10.8 oz (no adapter) / 13.3 oz with Xeno

Ordering & transfer

How you'll receive it

Ordered to build: your card is charged at checkout and we place the order on our dealer allocation the same day. Call us if you would rather reserve it with a deposit and pay the balance before transfer.

  • Pick up in Lake Stevens, by appointment (Washington residents), once ATF approves your Form 4. Bring government photo ID; we complete the Form 4473 with you at pickup. Washington's state background check and ten-business-day wait apply to firearms, not to a suppressor, so there is no state fee on this item.
  • Ship to your dealer in any state where this item is legal, free of charge. Your dealer emails us a signed copy of their licence (27 CFR 478.94); we match it against ATF's FFL eZ Check before it ships. Their transfer fee and state rules apply at pickup.
  • NFA item. Washington buyers: we file the ATF Form 4 with you here (passport-quality photo; fingerprints on cards or digital capture, $50 optional; individual or trust). Out-of-state buyers: it goes to your SOT dealer on a Form 3 and they file your Form 4. The federal transfer tax on suppressors has been $0 since 1 January 2026. When you buy the suppressor from us, our $125 NFA transfer fee is included; the only extra is digital fingerprints, $50 and optional.

Status of an order or build: call (844) 289-1911 or email hello@precisionshooting.us. We also email you when a build starts.
