Dead Air Sierra 5 is a new suppressor out there in the real steel market and The Firearm Blog tries one out to check if it's one of the best available right now... "In this episode of TFBTV, James Reeves reviews the Dead Air Sierra 5 and asks – is this the best deal going in suppressors for the AR-15 right now? Starting at just $699 for a suppressor, HUB compatible mounting device (KeyMo or Xeno), and a muzzle device, the Sierra 5 drives a hard bargain. James tests this new suppressor out with an SBR IWI Tavor X95 Micro, the new Smith & Wesson Volunteer M&P15, and even the FN P90 to see how it performs and to give his opinion."
