Dead Air Armament Blast Shroud .458 Cal For Hub Adapter 1-3/8-24'' Thread

The Dead Air Armament Blast Shroud in .458 caliber is a muzzle device designed to redirect concussion and muzzle blast away from the shooter and bystanders on short-barrel rifles and unsuppressed carbines. This .458 Cal shroud threads onto Dead Air Hub Adapters with a 1-3/8-24" thread pattern, making it a straightforward addition to rifles running Dead Air muzzle devices or suppressors. If you're shooting SBRs or PCCs without a suppressor, the Blast Shroud transforms what can be an unpleasant shooting experience—especially in tight quarters or when shooting alongside others—into something far more manageable.

Dead Air engineered the Blast Shroud to redirect gas and concussion forward of the muzzle rather than back toward you and nearby shooters. The result is noticeably less ear-ringing, reduced concussion signature, and a cleaner shooting environment that keeps your shooting buddies from offering lethal stares between strings. The linear design also helps minimize muzzle rise, which means faster follow-up shots and an easier time maintaining your sight picture when accuracy matters.

Built from 4140 HT alloy steel with a black nitride finish, the Blast Shroud is compact at just 1.87 inches long and weighs only 3.1 ounces—light enough that it won't throw off your barrel harmonics or require heavy recoil compensation. Dead Air's modular architecture means the shroud and its adapter components work with other Dead Air suppressors and accessories, giving you flexibility to reconfigure for different setups as your needs change. If you run a short barrel and want to keep things unsuppressed, this is a practical way to make shooting more pleasant for everyone downrange.
