The Dead Air Blast Shroud with DA428 KeyMo Adapter is an accessory built to reduce muzzle concussion and flash from short-barreled rifles and pistol-caliber carbines (Dead Air part no. DA463KM). It is constructed from 4140 HT alloy steel with a black nitride finish and directs concussion forward rather than back at the shooter, for a more comfortable shooting experience for the user and anyone standing nearby. The included KeyMo adapter gives it a quick, secure HUB (1 3/8-24) mounting interface compatible with other Dead Air accessories and suppressors. At 3.11 inches long and 7.4 ounces, it adds minimal length and weight to the muzzle.

Frequently Asked Questions

Is this itself a suppressor or NFA item? No. This is a Title I accessory (a mount, adapter, or muzzle device) that a suppressor threads onto or connects with; it is not a regulated suppressor itself and does not require an ATF Form 4 to purchase.

What does this shroud actually do? It reduces muzzle concussion and flash by directing blast forward, away from the shooter and bystanders, rather than reducing sound the way a true suppressor does.

What mounting system does it use? It includes a DA428 KeyMo adapter, giving it a HUB (1 3/8-24) thread interface compatible with other Dead Air accessories and suppressors.
