Anyone who has spent time behind a short-barreled rifle knows the real problem is not recoil, it is the wall of concussion that comes back at you and everyone standing nearby. The Dead Air Blast Shroud DA464S was built to fix exactly that. It mounts over your existing Dead Air muzzle device using a DA429 KeyMo adapter or any other 1-3/8-32 threaded adapter, then redirects the flash and blast forward of the muzzle where it belongs. The difference on the firing line is immediate, both for you and the folks in the lanes next to you.
Beyond the comfort factor, this shroud pulls double duty as a linear compensator. By driving gases forward, it helps flatten muzzle rise so your sights stay on target for quicker follow-up shots. On a short barrel, it also extends the muzzle out past your support hand, which adds a welcome margin of safety when you are running an aggressive grip on a stubby gun. The .458 caliber through bore gives you plenty of clearance for big-bore builds and everything smaller, making it a natural fit on unsuppressed SBRs and pistol-caliber carbines alike.
The shroud body is machined from 4140 heat-treated alloy steel, the same tough stuff Dead Air uses across its muzzle device family, so it shrugs off the heat and abuse that comes with sitting at the business end of a rifle. It is also part of Dead Air's modular ecosystem, meaning the components interchange with other Dead Air accessories and suppressor mounts. Swap adapters and you can move this shroud between hosts as your collection grows.
Keep in mind this is the shroud-only version, so it is the right pick if you already own a DA429 KeyMo adapter or another 1-3/8-32 mount. If you shoot next to friends or spend range days on a covered line, this is one of those upgrades everyone around you will appreciate as much as you do.
No, this is the shroud-only version. It is designed for folks who already own a DA429 KeyMo adapter or another 1-3/8-32 threaded adapter. If you need the complete package, Dead Air sells the DA464 kit that bundles the shroud with the DA429 adapter.
The through bore measures .458 caliber, so it clears anything at or below that diameter. That covers big-bore rounds like .458 SOCOM and .450 Bushmaster along with 5.56, .300 Blackout, 9mm, and other common SBR and PCC calibers. Just make sure your bullet diameter stays under .458 and your mount matches the 1-3/8-32 thread.
Not in the way a suppressor does. It redirects the blast, flash, and noise forward of the muzzle instead of letting it slap back at you and the shooters beside you. The gun is still loud downrange, but the experience behind the trigger and on a crowded firing line is noticeably more pleasant.
Yes, that is one of the perks of Dead Air's modular design. The shroud components interchange with other Dead Air accessories and suppressor mounts, so with the right adapters you can swap it between hosts. Run a compatible Dead Air muzzle device on each rifle and moving the shroud takes just a few seconds.
