The Dead Air Silencers Blast Shroud with KeyMo Adapter (Dead Air part number DA464) is a 1-3/8×32-threaded heat shield and mounting adapter built for .458-class hosts. Like the rest of Dead Air’s blast shroud lineup, it is an accessory piece rather than a suppressor itself, giving KeyMo-equipped hosts a protective shroud along with the correct thread pitch adapter to mount up cleanly. Shooters running Dead Air’s KeyMo mounting system on a large-bore host use this shroud to add heat and blast protection at the muzzle without altering the host firearm itself, making it a straightforward accessory purchase rather than a regulated item on its own.
