The Dead Air Nomax 33 black suppressor with Xemax adapter is Dead Air’s answer for .338-caliber shooters who want to suppress a long-range rifle without carrying a heavy can (Dead Air part no. NOMAX33XEMAXBLK). Dead Air describes it as an exceptionally quiet, ultralight silencer that draws on 3D printing and decades of suppressor research. The body is Grade 5 titanium with a 6,800 ft-lb energy rating, and the Xemax brake and adapter bring the overall length to 9.60 inches. It fits the hunter or precision shooter running a .338 Lapua bolt gun who wants a can without the bulk of a steel one.
