Dead Air Sierra-5: The New 5.56 Suppressor

The Sierra-5 is a brand new dedicated 5.56 silencer from Dead Air. Full-auto rated with no restrictions on barrel length, the Sierra-5 is purpose built for hard-use. This durability and longevity is achieved through welded Stellite® baffles wrapped in a stainless steel outer tube — a proven combination. The iconic exterior knurling increases surface area, expediting the cool-down process.

The Sierra-5 strikes the ideal balance between a small footprint, effective flash hiding, and 5.56-taming sound suppression. Compatible with HUB (1.375-24”) mounting adapters, the Sierra-5 can be purchased with either a Keymo or Xeno Mount with a corresponding 1/2-28 Flash Hider.
