Dead Air Armament Blast Shroud .458 Cal W/Da429 Keymo Adapter 1-3/8-32 Thread
The Dead Air Armament Blast Shroud in .458 caliber with DA429 KeyMo adapter is a muzzle device designed to reduce the sharp concussion and flash blast that comes with short-barreled rifles and pistol-caliber carbines. Mounted directly to your barrel or over existing Dead Air muzzle devices, it redirects the concussive energy and flash forward, away from the shooter and nearby range mates. If you've ever winced at the brutal impulse of a short-barrel .458 or watched your shooting buddy recoil from the sonic blast, this shroud transforms that experience into something actually tolerable—keeping everyone on the line happier and faster on follow-up shots.
The shroud's design also serves a practical function beyond noise and concussion reduction. By extending the muzzle further from your support hand on shorter rifles, it reduces the risk of your hand drifting into the blast cone, a real hazard on compact platforms. The linear compensation geometry minimizes muzzle rise, helping you maintain your sight picture between rounds so you can shoot faster and more naturally without fighting the gun.
Built from 4140 heat-treated alloy steel with black nitride finish, the Blast Shroud is constructed to withstand hard use. At 3 inches long and 7.6 ounces, it adds minimal bulk while delivering measurable concussion management. The shroud threads directly to your barrel at 1-3/8-32, and the included DA429 KeyMo adapter allows integration with other Dead Air suppressors and accessories—the modular architecture means you're not locked into a single configuration. Swap adapters, layer it with other Dead Air components, and build the muzzle setup that fits your rifle and your mission.
