New from Dead Air Silencers is the Sierra 5, their first dedicated 5.56 (5.56/.223, 224 Valkyrie) can.
There are two versions, compatible with either KeyMo (top) or Xeno (bottom) mounting systems as well as a direct thread model.
The construction is welded Stellite baffles wrapped in a stainless, knurled outer tube. Stellite is a Cobalt alloy with a 2300 F melt point.
It also has a flash hider front cap compatible with Sandman E-Brake and all R-Series front caps which can be swapped out in the event of a front cap strike.
Here you can see the difference in size between the Sierra 5 (bottom) and Dead Air’s military issue suppressor.
