Product Description

From the beginning, Dead Air's mission has been to give No Quarter in design, performance, and technology. The Sierra 5 stands true to that mission by giving you everything you want from a dedicated 5.56 silencer. This is a hard-use silencer. They are not cutting costs or shortening lifespan by using stainless-steel baffles. They are not sacrificing durability to save a few ounces. The Sierra 5 is full-auto rated with no barrel-length restrictions. Love or hate the knurling, it's function over form, directly inline with Dead Air's goal when developing the Sierra 5. Frankly, if you don't get the Sierra 5 red hot each time you shoot it, they might be offended.
