Dead Air Armament Blast Shroud .458 Cal For Da429 Keymo/Other 1-3/8-32 Adaptrs

The Dead Air Armament Blast Shroud in .458 caliber is a muzzle device engineered to tackle the blast signature and concussion that comes with short-barreled rifles and pistol-caliber carbines. Built for shooters who want a more comfortable range experience—and want to keep the peace with everyone shooting nearby—this shroud mounts over existing Dead Air muzzle devices or threads directly with compatible adapters, including DA429 KeyMo and 1-3/8-32 threads. Instead of letting muzzle blast and flash dominate your shooting line, the Blast Shroud redirects that energy forward, away from you and your neighbors' ears.

One of the standout benefits is linear compensation: the shroud's design keeps muzzle rise minimal so you maintain your sight picture through rapid follow-up shots. On short-barreled guns, where the muzzle sits close to your hand, the Blast Shroud also pushes the blast signature further out in front, reducing the risk of your support hand catching muzzle energy. It's a practical solution for the shooter who values control, speed, and courtesy on the range.

Dead Air built this shroud with modularity in mind. The parts are interchangeable with other Dead Air accessories and suppressors, so you can easily reconfigure it for different applications and caliber setups as your arsenal grows. Constructed from 4140 HT alloy steel with a black nitride finish, it's built tough and engineered to handle the abuse of duty-grade use.
