The Dead Air Blast Shroud with DA455 Xeno Adapter (brand part no. DA463XN) mounts over a Dead Air muzzle device to divert muzzle blast and flash forward, away from the shooter and anyone standing nearby. Rated for use up to .458 caliber, the shroud pairs with the DA455 Xeno Adapter, a suppressor-mounting interface that uses left-hand threads on a 1-3/8-24 HUB pattern to lock up with Dead Air’s Nomad-series suppressors and other compatible mounts. Machined from heat-treated 4140 alloy steel and finished in black, the combination sits at a shallow depth in a suppressor’s blast chamber, which helps minimize focused baffle erosion and extend service life. For suppressor owners who want a more comfortable shooting position and a secure mounting interface, this NFA accessory is built to match Dead Air’s mounting system.

Frequently Asked Questions

Does the Blast Shroud reduce sound like a suppressor? No, it redirects muzzle blast and flash forward for shooter comfort; sound reduction still comes from the suppressor mounted through the Xeno Adapter.

What suppressors work with the Xeno Adapter? Dead Air’s Nomad-series suppressors and other suppressors using the same 1-3/8-24 HUB mounting pattern.

Why does the adapter use left-hand threads? Left-hand threads keep the adapter from unthreading when the suppressor is removed and let shooters confirm the mount is tight.
