The Dead Air Blast Shroud with the DA428 KeyMo HUB Adapter (Dead Air part no. DA463KM) is a shroud kit that tames concussion on short-barreled rifles and pistol-caliber carbines. The shroud diverts flash and blast forward of the muzzle, and the included KeyMo adapter lets it quick-attach to KeyMo muzzle devices. It is a longer, heavier kit than the shroud-only models, and the adapter is what makes it a complete mounting package. Dead Air builds the kit from 4140 heat-treated steel and 17-4 stainless with a black nitride finish.

Key Specifications

• The included adapter is the DA428 KeyMo HUB Adapter, so the kit mounts as a complete assembly.
• Overall length is 3.11 inches, which places the muzzle farther from your support hand on a short barrel.
• Weight is 7.4 ounces, the heavier end of Dead Air’s shroud kits.
• The through bore is .458 caliber, the clearance this kit offers.
• Materials are 4140 heat-treated steel and 17-4 stainless, a split that keeps the shroud tough and the adapter corrosion resistant.
• The finish is black nitride, which wears well on a part at the muzzle.
• Function includes linear compensation, which Dead Air says reduces muzzle rise to hold the sight picture for follow-up shots.
