READ CAREFULLY.... Rifle is not included.
I used a Plan-B mount from Q to install it on the rifle, so this thing has a lot of versatility!

The innovative minds at Dead Air Silencers have raised the bar with their latest suppressor, the Dead Air Sierra 5. The Sierra 5 is a compact, durable suppressor available in one of two mounting options: Xeno mount and KeyMo mount. The Xeno mount configuration measures only 5.72” long and weighs just 13.3 oz. Engineered using high-quality, laser-welded stellite baffles, The Sierra 5 from Dead Air is designed specifically for 5.56 or .223 ammo.

 The Sierra 5 is compatible with any Dead Air R-series front cap, like the Sandman E-Brake. What does the Dead Air E-Brake do? The E-Brake reduces recoil and you can easily attach and detach the Dead Air Sierra 5.56 on your host with the functional knurling on the outer tube. Get one of the best performing and toughest dedicated 5.56 suppressors available in the Sierra 5.
