The Dead Air Blast Shroud with DA428 KeyMo Adapter is engineered to significantly reduce muzzle concussion and flash from short-barreled rifles and pistol-caliber carbines. Constructed from rugged 4140 HT alloy steel with a black nitride finish, this blast shroud directs concussion forward, creating a safer and more comfortable shooting experience for the user and those nearby. Its modular architecture allows for compatibility with other Dead Air accessories and suppressors, and the included KeyMo adapter offers quick and secure mounting to HUB (1 3/8-24) threaded muzzle devices. At 3.11 inches in length and weighing just 7.4 ounces, this robust shroud is ideal for enhancing control and reducing blast without compromising maneuverability.
